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?

Written by Pendell Meyers, with edits by Steve Smith Thanks to my attending Nic Thompson who superbly led this resuscitation We received a call that a middle aged male in cardiac arrest was 5 minutes out. There is a regular, wide complex, (mostly) monomorphic tachycardia. He was estimated to be in his 50s, with no known PMHx.

BACKGROUND:In severely affected patients with catecholaminergic polymorphic ventricular tachycardia, beta-blockers are often insufficiently protective. The primary end point was AEs, defined as sudden cardiac death, sudden cardiac arrest, appropriate implantable cardioverter defibrillator shock, and arrhythmic syncope.

It was reportedly a PEA arrest; there was no recorded V Fib and no defibrillation. He had multiple cardiac arrests with ROSC regained each time. This patient arrested shortly after hospital arrival. CPR was initiated immediately. Initial ROSC was obtained, during which this ECG was obtained: What do you think?

A 60-something woman presented after a witnessed cardiac arrest. She was never defibrillated. This is commonly found after epinephrine for cardiac arrest, but could have been pre-existing and a possible contributing factor to cardiac arrest. Cardiac cath showed minimal disease. She recovered.

Cardiac sarcoidosis (CS), a rare condition characterized by non-caseating granulomas, can manifest with symptoms such as atrioventricular block and ventricular tachycardia (VT), as well as mimic inherited cardiomyopathies. An endomyocardial biopsy (EMB) confirmed the diagnosis of cardiac sarcoidosis.

She underwent cardiopulmonary resuscitation for VT/VFib — with ROSC ( R eturn O f S pontaneous C irculation ) following defibrillation and treatment with Epinephrine and Amiodarone. A series of cardiac arrhythmias were seen during the course of her resuscitation — including the interesting arrhythmia shown in the long lead II of Figure-1.

Although one may have all kinds of ischemic findings as a result of cardiac arrest (rather than cause of cardiac arrest), this degree of ST elevation and HATW is all but diagnostic of acute proximal LAD occlusion. This prompted cath lab activation. On arrival to the ED, this ECG was recorded: What do you think?

The ECG in Figure-1 — was obtained from a middle-aged man who presented to the ED ( E mergency D epartment ) in cardiac arrest. The rhythm is regular — at a rate just over 100/minute = sinus tachycardia ( ie, the R-R interval is just under 3 large boxes in duration ). Should you activate the cath lab?
