Acute myocardial ischemia. Despite prolonged resuscitation with multiple defibrillation attempts — the patient could not be saved. = See My Comment in the June 1, 2020 post in Dr. Smith's ECG Blog — for review of Pleomorphic VT. CPVT ( Catecholaminergic PolyMorphic VT ). Familial hypokalemic periodic paralysis.

The first task when assessing a wide complex QRS for ischemia is to identify the end of the QRS. The ST segment changes are compatible with severe subendocardial ischemia which can be caused by type I MI from ACS or potentially from type II MI (non-obstructive coronary artery disease with supply/demand mismatch). What do you think?

He required multiple defibrillations within a period of a few hours. There is no definite evidence of acute ischemia. (ie, This time, the arrhythmia did not spontaneously terminate — but rather degenerated to VFib, requiring defibrillation. Some residual ischemia in the infarct border might still be present.

He underwent further standard resuscitation EXCEPT that we applied the Inspiratory Threshold Device ( ResQPod ) AND applied Dual Sequential Defibrillation (this simply means we applied 2 sets of pads, had 2 defib machines, and defibrillated with both with only a fraction of one second separating each defibrillation.

She was successfully revived after several rounds of ACLS including defibrillation and amiodarone. Alternation in ST segment appearance ( or in the amount of ST elevation or depression ) — is often linked to ischemia. On arrival to the ED the patient was intubated with normal vital signs.

Tackling SCD was in God’s domain, until the brilliance of Dr. Michel Mirowski shrunk the defibrillator and implanted it under the chest in 1980. (Dr. 2020) The un-disputable fact is ischemic DCM has a target to treat, though it is termed as cardiomyopathy. SCD is the leading cause of mortality in heart failure. N Engl J Med.

This episode self terminated before defibrillation was possible. That said — in a patient who develops TdP — the overall ECG appearance of this initial ECG is consistent with low K+ and/or low Mg++ ( See My Comment in the May 9, 2020 post — for more on the ECG diagnosis of hypokalemia and hypomagnesemia ).
