During the night, while on telemetry, the patient became bradycardic, with periods of isorhythmic AV dissociation (nodal escape rhythm alternating with sinus bradycardia), and there were sporadic PVCs. The above ECGs show the initiation and continuation of a polymorphic ventricular tachycardia. Without an MRI, it is impossible to know.

How a pause can cause cardiac arrest

Dr. Smith's ECG Blog

While on telemetry monitoring he suffered cardiac arrest and was resuscitated. What ECG finding may have contributed to (or precipitated) the cardiac arrest? Learning points : Takotsubo can lead to cardiac arrest from ventricular arrhythmia. There are no clear signs of OMI. There is a prolonged QTc.

There was concern that the rhythm might represent ventricular tachycardia, so lidocaine was given and one attempt at cardioversion was performed.

A middle aged man with unwitnessed cardiac arrest

Dr. Smith's ECG Blog

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.

Could you have prevented this young man's cardiac arrest?

Dr. Smith's ECG Blog

We received 4 ECGs, including his baseline on file, and three from today, including triage, peri-arrest, and post-ROSC (sorry for the poor quality due to scanning). Prior ECG on file: Sinus tachycardia, imperfect baseline, otherwise unremarkable. Unfortunately, this was not recognized at this time.

What are treatment options for this rhythm, when all else fails?

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.

Tachycardia, fever to 105, and ischemic ST Elevation -- a Bridge too Far

Dr. Smith's ECG Blog

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.
