Emergency Medicine Mnemonics

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...

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 lea...

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 B...

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 inte...

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

• 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...

In this high-yield episode, we build a visual memory palace down the “Highway to Hell” of emergency thrombocytopenia syndromes. Each stop reveals a unique and dangerous cause of low platelets you’ll encounter in the ED—brought to life through vivid storytelling, unforgettable characters, and layered mnemonics.

🚑 What You’ll Learn (Quick Hits):

In this episode, we tackle STEMI mimics—conditions that mimic ST-segment elevation myocardial infarction on an EKG but aren’t always a heart attack.

Why’s it critical? Because ST elevation doesn’t always mean STEMI, and misdiagnosis can waste time or miss critical conditions.

How to Mix Push-dose Epi: One out, one in — makes ten

Goal concentration: 10 mcg/mL

Step-by-Step Mixing:

1. Start with a 10 mL syringe of normal saline (NS)

• empty 1 mL to retain 9 mL of NS in the syringe.

2. Use the code cart 1:10,000 epi (100 mcg/mL)

• This is the standard “cardiac arrest epi” amp (usually 1 mg in 10 mL)…the 1:10,000 prefilled syringe used during ACLS

3. Withdraw 1 mL of the 1:10,000 epi (this gives you 100 mcg) u...

E-MOTIVE Mnemonic for Postpartum Hemorrhage: A Lifesaving Strategy

The E-MOTIVE mnemonic stands for a six-component bundle aimed at tackling postpartum hemorrhage (PPH), a major cause of maternal death, especially in low-resource settings. This approach, tested in a cluster-randomized trial across 80 hospitals in Kenya, Nigeria, South Africa, and Tanzania, was published in the New England Journal of Medicine in 2023. Here’s what...

This is a Neonatal Resuscitation Algorithm flowchart, specifically the NRP (Neonatal Resuscitation Program), published by the AHA in 2020. It provides a step-by-step guide for healthcare providers to follow during the resuscitation of a newborn immediately after birth, focusing on stabilizing the infant’s breathing, heart rate, and oxygenation.

The 3-Step Approach to Acute Hyperkalemia

1. Stabilize: the Heart (If ECG changes) → Calcium

2. Shift: K+ Into Cells → Insulin + Glucose, Albuterol, Bicarb (if acidotic)

3. Send-it: Remove K+ From Body → Diuretics (if making urine), Kayexalate (if GI motility intact), Dialysis (if severe/refractory)

I – IV Fluids

C – Calcium

B – Beta-2 Agonists

B – Bicarbonate

I – Insulin & Glucose

K – Kayexalate (Sodium Polystyrene Sulfonate)

D – Diu...

USED CARS mnemonic for non-anion gap metabolic acidosis (NAGMA):

Why “USED CARS”?

• Ureterosigmoidostomy

• Saline & Chloride infusion (excessive).. chloride offsets AG

• Endocrine disorders (Addison’s disease aka adrenal insufficiency, hypoaldosteronism)

• Diarrhea

• Carbonic anhydrase inhibitors

• Ammonium chloride

• Renal tubular acidosis

• Spironolactone

The GOLD MARK causes are divided into three major pathophysiologic groups based on the source of the acid production:

1. Alcohols (Toxic Ingestions) → Emergency Toxins

• Glycols → Ethylene glycol (antifreeze) and propylene glycol

• Methanol → Windshield washer fluid, homemade alcohol substitutes

• Why grouped together?

• Common in suicide attempts, accidental ingestions, or chronic alcoholics.

• Key labs: Serum osmolality, ...

Mister Ronald McDonald (MR RM) is a helpful flowchart for interpreting acid-base disorders, specifically for determining whether a patient’s condition is due to a metabolic (M) or respiratory (R) cause:

1. Check the pH (7.4 is the cutoff)

• pH > 7.4 → Alkalosis

• pH < 7.4 → Acidosis

2. Assess Carbon Dioxide (CO₂) Levels (PaCO₂)

• The key threshold is 40 mmHg:

• If CO₂ > 40 mmHg, this suggests respiratory acidosis or metaboli...
