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. Cardiac arrest was called and advanced life support was undertaken for this patient. Without an MRI, it is impossible to know.

While on telemetry monitoring he suffered cardiac arrest and was resuscitated. What ECG finding may have contributed to (or precipitated) the cardiac arrest? After resuscitation and defibrillation , there were no more episodes of TdP. Below is the patient’s 12 lead ECG following defibrillation.

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 were two monitor spikes for every one electrical cycle on the cardiac monitor. Learning Points: 1.

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.

This false electrical capture may have made cardiac arrest recognition difficult, and the re-arrest may have gone unrecognized for an unknown amount of time. Learning points: TCP is primarily recommended for bradycardia that does not respond to atropine, or other agents. Current 85mA. On ED arrival ROSC is achieved.

She was unable to be defibrillated but was cannulated and placed on ECMO in our Emergency Department (ECLS - extracorporeal life support). After good ECMO flow was established, she was successfully defibrillated. There is sinus bradycardia with one PVC. An elderly woman had sudden ventricular fibrillation. The K was normal.

He required multiple defibrillations within a period of a few hours. This time, the arrhythmia did not spontaneously terminate — but rather degenerated to VFib, requiring defibrillation. Some episodes of PMVT would terminate spontaneously — but on many occasions, the PMVT degenerated to VFib, requiring defibrillation.
