Most podcasts are about understanding. This emergency medicine podcast is about knowledge recall. Active learning requires your brain to process actively. Can you withstand sitting with the discomfort of being asked a question until you can answer it easily and readily? I promise you won’t be comfortable listening to each episode, but after you withstand the discomfort, your ability to recall, will be far superior than any other passive, listening.

  1. Sick-Tachy or Tachy-sick: S.T.O.P. Secondary Compensations (Must-consider Differentials)

    11 SEPT.

    Sick-Tachy or Tachy-sick: S.T.O.P. Secondary Compensations (Must-consider Differentials)

    When the heart rate blasts past 150, our reflex is often to grab a syringe—diltiazem, metoprolol, something to slow things down. But here’s the hard truth: if the patient is in sick-tachy—tachycardia as a secondary compensation—slamming them with rate control can be catastrophic. That racing heart rate may be the only thing keeping them alive. Pausing to ask “sick-tachy or tachy-sick?” is what separates the new learner from the confident emergency clinician. This episode is all about STOP-ping before you treat the number. STOP is your mnemonic for the must-consider secondary compensations that drive tachycardia in the ED. Each of these can mimic or mask primary arrhythmias, and missing them can lead to disaster: ⸻ 🛑 STOP Mnemonic S – Sepsis • Tachycardia is often the earliest sign of infection. • Always check a lactate—“Lactic Acid” should be etched in your mind. • Bundle: fluids + source control. • Be cautious in elderly or vague abdominal presentations; tachycardia may be your only clue. T – Thyroid Storm • Look for agitation, fever, tremor, weight loss history. • Order TSH/T3/T4. • Treatment anchor: Beta-blockers (BB) are first-line for rate control here—unique compared to other scenarios. • Missing thyroid storm means missing a reversible cause of near-fatal tachycardia. O – HypOvolemia • Think bleeding (low H/H), dehydration, or anemia. • Visual: half water / half blood glass—“Fill the Tank.” • Don’t just reach for meds—give fluids, transfuse, and stabilize volume first. • Remember also anxiety/pain can amplify sympathetic tone. P – Pulm/Cards (Cardiopulmonary) • Pneumonia – fever, infiltrate, hypoxia. • Pneumothorax – sudden pleuritic chest pain, absent breath sounds. • PE – unexplained hypoxia, pleuritic pain, risk factors. • CHF (low EF) – the most dangerous one to miss before you push AV nodal blockers. • Workup tools: ABG, BNP, CTPA, CXR, POCUS. ⸻ 🧠 Why This Matters • Sinus tachycardia is often appropriate—but it can mask life-threatening systemic illness. • Medicating away compensation without treating the cause can pull the plug on the patient’s only survival mechanism. • STOP first before flipping to tachyarrhythmia algorithms (SVT, AFib w/ RVR, VT, Torsades, VF). ⸻ ⚡ Clinical Pearls • Always ask: Stable or unstable? Unstable → Shock immediately per ACLS. • If stable → STOP. Consider secondary compensations before rhythm drugs. • POCUS is your left-hand tool—look for low EF before you dare to push AV nodal blockers. • Gradual vs sudden onset helps distinguish sick-tachy (gradual, compensatory) from tachy-sick (primary arrhythmia, often sudden). • Repetition is your friend—STOP, STOP, STOP until it becomes second nature. ⸻ 🎧 In this episode, you’ll learn how to build a jetpack framework for HR >150 that keeps you calm under pressure, helps you avoid rookie mistakes, and makes sure you never miss the underlying killer hiding beneath “just a fast heart rate.” STOP first. Then treat.

  2. 6 S’s & 6 H’s Heart Score: Chest Pain & Diamond Classification Risk Stratification

    11 SEPT.

    6 S’s & 6 H’s Heart Score: Chest Pain & Diamond Classification Risk Stratification

    Chest pain is one of the most common—and highest risk—complaints in the ED. Missing acute coronary syndrome can be catastrophic, but keeping every patient in the hospital isn’t realistic either. That’s why the HEART score has become the standard of care: a simple, validated tool to help you decide who is safe for early discharge and who needs further workup or cardiology assessment. In this episode, I’ll show you how to remember and apply the HEART score effortlessly by flipping it into the 6 S’s and 6 H’s framework—a diamond-shaped way to risk-stratify chest pain that you can run through in real time, right at the bedside. This method blends the Diamond classification of angina with the HEART score, anchoring it to recall cues you’ll never forget. Once you master the S’s and H’s, you’ll be able to calculate HEART quickly, communicate clearly, and avoid missing high-risk patients. Of course, always follow your local protocols—but for every chest pain encounter, remember: ALWAYS calculate the HEART score. ⸻ 💎 6 S’s & 6 H’s: The Framework S’s — Symptoms, ECG, Risk factors, Age Suspicious Symptoms (Diamond criteria) 1 . Substernal ​ Stress-related (worse with exertion)​ Stops with rest​ Bonus: Sweating→ Typical angina = 3/3 → Atypical angina = 2/3 → Non-anginal = 0–1 ​ ST Changes on ECG​ Normal → 0​ Non-specific (LVH, digoxin, etc.) → +1​ Significant ST depression/elevation → +2​ Smoking (or Vaping)​ Still a major ASCVD risk factor​ Ask specifically in younger patients​ Sixty-Five (Age ≥65)​ 30)​ History (Family hx 3× normal → +2 ⸻ ⚠️ Pearls & Pitfalls ​ MACE = Major Adverse Cardiac Events.​ HEART pathway randomized trial (Mahler, 2015) → validated early discharge.​ The HEART score is not universal—there are exceptions; know when it doesn’t apply.​ Enough S’s & H’s → They Stay in the Hospital. ⸻ 👉 Whether you’re on shift, teaching, or reviewing for boards, this episode makes the HEART score second nature. Save time, reduce misses, and risk stratify chest pain with confidence.

  3. STEMI ischemic and reciprocal change patterns

    STEMI ischemic and reciprocal change patterns

    In a cardiac emergency, pattern recognition saves lives. The ability to rapidly identify ST-elevation myocardial infarctions (STEMIs) — and recognize their reciprocal changes — is one of the most high-yield clinical skills you can master. But memorizing lead groupings, artery territories, and reciprocal zones can feel abstract… until now. This podcast brings EKGs to life inside a colorful, stadium-themed world where each ECG lead is a character in the crowd — making it dramatically easier to remember the key patterns of ischemia and their reciprocals. Whether you’re a student, clinician, or educator, this episode transforms clinical EKG interpretation into vivid, unforgettable storytelling. 🧠 Characters You’ll Meet: • Inferior Peasants (II, III, aVF) — Dirty, disheveled townsfolk crowd-surfing with broken RC cars (Right Coronary Artery), holding crossed-out nitro packs to remind us: No nitro in RCA infarcts! • Royal Ladder Holders (I, aVL, V5, V6) — Crowned kings and queens dropping through trapdoors as reciprocal ST depression hits the lateral leads, each holding golden ladders labeled Left Circumflex. • Cavemen with Septal Bones (V1–V2) — Giant-nosed, primitive figures gripping a huge bone marked SEPTAL, standing just in front of… • Shirtless Musclemen (V3–V4) — Tattooed with the word Anterior, these strongmen are chained to a floating AC unit labeled Left Ventricle — representing the LAD (Widowmaker). • Posterior Posts (V7–V9) — Hydraulic pylons rising behind the wall, symbolizing posterior MI that’s often missed without reciprocal signs. 🎯 Quick Reference Patterns Covered in the Episode: ⸻ ✅ Inferior MI (II, III, aVF) • ST elevation: Inferior leads • Reciprocal depression: I, aVL (high lateral) → “When the peasants rise, the royals fall.” ✅ High Lateral MI (I, aVL) • ST elevation: High lateral leads • Reciprocal depression: III, aVF → Works both ways: “The balcony royals rise, the peasants fall.” ✅ Posterior MI (V7–V9) • ST elevation: Posterior wall (not on standard 12-lead!) • Reciprocal depression: V1–V3 → “When posterior posts rise, septal cavemen drop.” ✅ Anterior MI (V2–V4) • ST elevation: Anterior leads • Possible reciprocal depression: II, III, aVF → Sometimes: “When the chest heroes rise, peasants tremble.” ✅ Low Lateral MI (V5–V6) • ST elevation: Low lateral leads • Reciprocal depression: V1–V2 (septal) → “Kings and queens rise, cavemen fall.” ⸻ 🔥 Bonus Insights: • Why reciprocal changes matter: They can confirm a true STEMI, suggest a larger infarct area, and sometimes reveal hidden infarctions (like posterior MIs). • LBBB & Reciprocal Thinking: LBBB distorts ST segments, but understanding the mirror logic behind “William” (LBBB) and “Marrow” (RBBB) helps clarify expected patterns. ST depression in V1–V2? May just be part of LBBB — unless it’s concordant… 📌 Use this episode as your visual and verbal anchor. Once you’ve seen the peasants, the royalty, the cavemen, and the Left Vent AC unit, you’ll never look at a 12-lead the same way again.

  4. LBBB Sgarbossa Criteria: 1 Excessive Disc, 2 Concordance Contact Lenses

    3 SEPT.

    LBBB Sgarbossa Criteria: 1 Excessive Disc, 2 Concordance Contact Lenses

    When a left bundle branch block (LBBB) throws a wrench into your ECG interpretation, how do you know if it’s a STEMI… or just baseline noise? In this unforgettable episode, we ride full throttle into the wild world of wide QRS complexes, Scarbossa criteria, and the modified rules that help unmask true occlusion amidst the electrical chaos. Visualize Evel Knievel launching off the QRS ramp — only to slam into the Left Bundle Branch Block cinder block. His forehead tattoo reads “Scar,” and as he collides, contact lenses fly from his eyes — one labeled “Any Lead ↑1mm” and the other, “V1–V3 ↓1mm” — representing concordant ST changes in opposite directions. Meanwhile, a giant frisbee labeled “EXCESSIVE DISC >25%” flies through the scene, reminding us of the Smith-modified criteria for proportional discordant ST elevation. You’ll learn: • Why LBBB and paced rhythms mask the usual signs of infarction • What “appropriate discordance” really means • The 3 ways Scarbossa criteria cut through the noise • How to visually anchor each criteria with unforgettable imagery • And why you only need one criteria to trigger concern This episode breaks down advanced electrophysiology into a high-octane, cartoon-style teaching experience you’ll never forget. Whether you’re a medical student, resident, PA, NP, or attending, this episode locks in high-yield ECG wisdom that sticks. ⸻ ✅ Smith-Modified Sgarbossa Criteria Used in Left Bundle Branch Block (LBBB) or Ventricular Paced Rhythm to detect Occlusion MI (OMI): You need only ONE of the following three to be positive: 1. Concordant ST Elevation ≥1 mm in any lead with a positive QRS ➤ ST segment is in the same direction as the QRS (both upright) 2. Concordant ST Depression ≥1 mm in leads V1–V3 ➤ ST segment and QRS are both downward in V1–V3 (anterior leads) 3. Proportionally Excessive Discordant ST Elevation: ➤ ST Elevation is ≥25% of the depth of the preceding S wave in a lead with a negative QRS ➤ This replaces the old “5 mm” rule with a more accurate proportional one 💡 You only need one of these three criteria to suspect occlusion MI in the setting of LBBB or ventricular pacing.

    EKG Basic Basic Basic Framework for EM Docs: Ischemia, Arrhythmias, Intervals, Anomalies

    This is the most basic, essential framework for EKG interpretation — built for emergency medicine clinicians who need clarity, speed, and confidence in the heat of the moment. Our brains are wired for movement and story. Just like remembering your morning routine — wake up, brush teeth, grab caffeine — we naturally recall sequences that follow a simple, visual narrative. In this episode, we harness that power by turning EKG interpretation into Evel Knievel’s most daring stunt ride. It’s not just a fun story — it’s a high-yield, easy-to-remember mental checklist that sticks, even under pressure. 🏥 Why it works in the ED: In emergency medicine, chaos is the norm. We don’t have time to think academically when a STEMI or arrhythmia is staring us in the face. That’s why we built this vivid, memorable sequence — rooted in the high-performance principle Michael Phelps used to win 23 Olympic gold medals: a set routine. You don’t rise to the occasion. You fall back on your training. 🏁 What you’ll hear in this episode: ​ 🏍️ Evel Knievel enters the EKG stadium: First, he scans for the big stuff — STEMI and reciprocal changes.​ 🛠️ Check engine light: T-wave inversions on his digital monitor.​ 📈 RPMs climbing: Smooth R-wave progression across the precordial leads.​ 🔍 Arrhythmia check: Is there a P for every QRS?​ 📏 The perfect ramp: PR interval = Evel’s takeoff — 120–200 ms.​ 🛵 Mobitz moped warning: PR lengthens before crashing (Wenckebach).​ ❌ Sudden moped disappearance: Mobitz II.​ ⚫ Unicycle of doom: Third-degree block — P and QRS totally disconnected.​ 🧠 Anomalies & Final Scan: Brugada, hyperkalemia (peaked Ts), Osborn waves, and when to order a posterior EKG. 🚨 Key Takeaways to Remember: ​ This story is your reliable sequence: scan for ischemia → check for arrhythmia → assess intervals.​ STEMI? Look for elevation + reciprocal depression — including the often-missed posterior wall (V7–V9).​ Rhythm? Ask: Is there a P for every QRS?​ PR = takeoff ramp. QT = safe landing zone.​ Mobitz I = gradual PR lengthening → dropped beat.​ Mobitz II = PR stays the same → sudden drop.​ Third-degree block = P and QRS divorced — high risk of instability.​ Brugada = beware of the “grave cross” in V1–V2. Ask about family history of sudden cardiac death.​ Prolonged QT = risk of torsades, syncope, or V-fib — know when to shock. 🎧 This is your EKG blueprint. Your Michael Phelps routine. Your Evel Knievel ride to interpretation mastery. Let’s ride.

  6. Macrocytic Anemia in the ED: My Liver Bleeds a Lot (part 3)

    11 AOÛT

    Macrocytic Anemia in the ED: My Liver Bleeds a Lot (part 3)

    Step into the macrocytic anemia caboose and remember the non-megaloblastic causes with the mnemonic My Liver Bleeds a Lot: • My → Multiple Myeloma (CRAB: Hypercalcemia, Renal failure, Anemia, Bone lesions) • Liver → Liver disease • Bleeds → Hemolysis • A → Alcohol use • Lot → Hypothyroidism We start at the front half of the caboose with the non-megaloblastic nun holding a sign with crossed-out “mega” dynamite, marking the absence of hypersegmented neutrophils. The kingpin character raises an alcohol bottle (liver logo) in a toast—reminding us of alcohol as a cause—bumping it into his tuxedo labeled “TSH > 10” for hypothyroidism. Above him, three red balloons drip a drop of blood onto the liver logo, tying in the phrase “My liver bleeds a lot.” In the back half of the caboose, the B12 sumo baby wears a bandanna labeled “MMA” for methylmalonic acid (elevated in B12 deficiency), reaching up toward a Sistine Chapel ceiling to touch a finger labeled “↑ homocysteine” (seen in both folate and B12 deficiency). These back-half characters remind us that megaloblastic macrocytosis does have hypersegmented neutrophils, and is tied to DNA synthesis problems. For alcohol-related macrocytosis, we recall Wernicke’s encephalopathy—classic triad: 1. Ophthalmoplegia (eye movement abnormalities) 2. Ataxia (gait disturbance) 3. Confusion (altered mental status) ED Application: • In AMS + alcohol use, always give thiamine before glucose to prevent progression to Korsakoff syndrome (confabulation, severe memory deficits). • Macrocytosis without anemia can be an early alcohol toxicity sign—screen for liver disease, nutritional deficiencies, hypothyroidism, and myeloma. • Suspect multiple myeloma? Check calcium, renal function, Hgb, and order imaging for bone lesions. • Non-megaloblastic macrocytosis = treat underlying cause (alcohol cessation, thyroid replacement, liver management, transfusion for hemolysis). • Megaloblastic macrocytosis = give B12/folate; avoid masking B12 deficiency with folate alone to prevent neurologic damage.

    In the fast-paced, high-stakes world of emergency medicine, every second matters—especially when it comes to sickle cell crisis. This podcast takes you straight to the heart of what matters most for ED clinicians, walking you through the essential “4 R’s” that can mean the difference between stabilization and rapid deterioration: • Recognize — Identify the telltale signs of sickle cell crises early. Understand presentations like acute pain episodes, acute chest syndrome, stroke, and splenic sequestration, and learn how to differentiate these from other causes of acute pain or respiratory distress. • Reverse — Act fast to correct life-threatening complications. From oxygen and aggressive IV fluids to urgent infection management, you’ll get evidence-based, bedside-ready strategies to halt progression. • Radiology — Know when and why to image. From chest X-rays in acute chest syndrome to brain imaging for suspected stroke, we’ll break down which modalities to order—and how to interpret findings in the sickle cell patient. • Refer — Recognize when escalation of care is critical. Whether to hematology, critical care, or transfer to a higher-level facility, we’ll cover the decision-making process and timing. Hosted with a focus on clinically relevant, ED-ready pearls, each episode blends: • Case-based storytelling — Putting you in the room with the patient, step-by-step. • Mnemonic-rich recall tools — Like our “crime scene outline” visual, with key stickers marking the 4 R’s across the patient’s limbs for fast memory anchoring. • Practical takeaways — What you can do immediately, what you must watch for, and what to avoid. The principles behind the Sickle Cell 4 R’s is delivered in a no-fluff, high-yield format designed for busy clinicians who want to sharpen their edge in real emergencies. Whether you’re a seasoned emergency medicine provider, a resident looking to solidify your sickle cell knowledge, or simply someone passionate about critical care, Sickle Cell Crisis: The 4 R’s will give you the skills and confidence to take decisive action when it matters most.
