This progressed to electrical storm , with incessant PolyMorphic Ventricular Tachycardia ( PMVT ) and recurrent episodes of Ventricular Fibrillation ( VFib ). There was no evidence bradycardia leading up to the runs of PMVT ( as tends to occur with Torsades ). He required multiple defibrillations within a period of a few hours.

ECG is consistent with severe hypokalemia and/or hypomagnesemia causing prolonged QT (QU) at high risk of Torsades (which is polymorphic ventricular tachycardia in the setting of a long QT interval).

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.

There is also bradycardia. Bradycardia puts patients at risk for "pause-dependent" Torsades de Pointes. Torsades in acquired long QT is much more likely in bradycardia because the QT interval following a long pause is longer still. See here for management of Polymorphic Ventricular Tachycardia , which includes Torsades.

A fast heartbeat is called tachycardia, while a slow heartbeat is called bradycardia in medical terms. Cardiac arrest Cardiac arrest is a medical emergency in which the heart stops pumping blood to the body. Electrocardiogram, echocardiogram, and some other tests are done for patients with cardiac arrest.

Descriptive analysis of the ECG in today's case reveals a regular, narrow tachycardia at ~130/minute , without clear sign of sinus P waves. But the rate is ~130/minute — which is a bit fast for sinus tachycardia. So IF this is sinus tachycardia with a sinoventricular rhythm — then we have to explain WHY the rate is this fast.

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.
