ST elevation of early repolarization may vary with the rate
This 49 yo black male presented with sudden substernal non radiating pleuritic chest pain on the day prior to presentation. Here is the…
Cardiac arrest, LBBB with STEMI on the ECG, but no Acute Coronary Syndrome!
This 80 year old with a history of CABG had a cardiac arrest. He was resuscitated after fairly prolonged down time, but regained…
Weakness due to Bradycardia due to Sick Sinus with Sinoatrial block, with Ashmann’s phenomenon
This post is from last December, and shows sinoatrial block. A reader was puzzled by why one p-wave conducted and another did not. I had…

Chest pain, tachycardia, diffuse ST elevation. What is the diagnosis?
First, I want you to see the ECG without a lot of clinical information: this 45 year old male presented with left chest pain: What…
Missed Acute MI, with coronary occlusion, evidence only by T-wave inversion in V2 and evolving ST depression in V3
A 39 yo otherwise healthy man with no risk factors was walking at the mall when he developed chest pressure. He presented to the ED…
What is the rhythm? Answer at the bottom.
An elderly woman presented with abdominal pain. Here is her ECG: This is easily mistaken for atrial flutter because the waves have a…
This is a quiz. The ECG is pathognomonic. Answer is at the bottom.
Hyperkalemia, with near sinusoidal pattern. Note very wide QRS, bizarre deep T-waves in V1 and V2, peaked T-waves in V4 and V5, long PR…
Reversible T-wave inversion — it reverses, then evolves, then reverses when ischemia is gone. Normalization of T-waves, NOT pseudonormalization.
A 62 yo male has had chest pain with exertion for 2 weeks. He began having chest pain at rest at 2AM, and presented at 7 AM. Here is his…
