He developed cardiac arrest shortly after the ECG in Figure-1 was recorded. IMPRESSION: Given the presence of a wide tachycardia — with 2 distinct QRS morphologies, and no sign of P waves — a presumed diagnosis of B i D irectional Ventricular Tachycardia has to be made. What is the most likely cause of this arrhythmia?

What is the cardiac rhythm shown in the long lead II rhythm strip? Figure-1: The initial ECG in today’s case — obtained from an elderly woman following successful resuscitation from cardiac arrest. ( C ASE C onclusion : I lack detailed follow-up from today's case — other than knowing that the Atrial Tachycardia was controlled.

Here was his initial ED ECG: There is sinus tachycardia at a rate of about 140 There is profound ST Elevation across all precordial leads, as well as I and aVL. If a patient presents with chest pain and a normal heart rate, or with shockable cardiac arrest, then ischemic appearing ST elevation is STEMI until proven otherwise.

This progressed to electrical storm , with incessant PolyMorphic Ventricular Tachycardia ( PMVT ) and recurrent episodes of Ventricular Fibrillation ( VFib ). The patient improved, and on Day-11 of the hospital stay — he was off inotropes and on a small dose of a ß-blocker. He required multiple defibrillations within a period of a few hours.

There was never ventricular fibrillation (VF) or ventricular tachycardia (VT), no shockable rhythm. The patient was unconscious BEFORE the cardiac arrest, at the same time that she had strong pulses. Therefore, cardiac arrest is NOT the etiology of the coma. There is sinus tachycardia at ~115/minute.
