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…
Respiratory Failure, Heart Failure, and Narrow Complex Tachycardia
A 60 yo female presented by ambulance in resp distress, requiring noninvasive ventilatory support. She had pulmonary edema and was near…
Subacute MI masked by a wide complex

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…

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…
Pseudonormalization of Inferior T-waves
