ECG Blog #435 — Did Cath Show Acute Ischemia?

Ken Grauer, MD

The ECG in Figure-1 — was obtained from a middle-aged woman with positional tachycardia and diaphoresis with change of position from suprine to sitting. My THOUGHTS on the ECG in Figure-1: The rhythm is sinus tachycardia at ~105/minute ( ie, The R-R interval is regular — and just under 3 large boxes in duration ).

Resuscitated from ventricular fibrillation. Should the cath lab be activated?

Dr. Smith's ECG Blog

The ECG shows severe ischemia, possibly posterior OMI. But cardiac arrest is a period of near zero flow in the coronary arteries and causes SEVERE ischemia. It takes time for that ischemia to resolve. The patient was brought to the ED and had this ECG recorded: What do you think? And what do you want to do?

Young Man with Very Fast Regular Wide Complex Tachycardia

Dr. Smith's ECG Blog

A prehospital 12-lead was recorded: There is a regular wide complex tachycardia. The computer diagnosed this as Ventricular Tachycardia. There is a wide complex regular tachycardia at a rate of 226. Toothache, incidental Wide Complex Tachycardia Could it be fascicular VT or Bundle Branch VT ( i.e., idiopathic VT )?

Elder Male with Syncope

EMS 12-Lead

Many of the changes seen are reminiscent of LVH with “strain,” and downstream Echo may very well corroborate such a suspicion, but since the ECG isn’t the best tool for definitively establishing the presence of LVH, we must favor a subendocardial ischemia pattern, instead. Type I ischemia. Type II ischemia.

What kind of AV block is this? And why does she develop Ventricular Tachycardia?

Dr. Smith's ECG Blog

Shortly after isoprenalin infusion was initiated, there were short runs of ventricular tachycardia. Extensive conduction system abnormalities can have various causes (ischemia, genetic, infectious, amyloid, etc). During the next 24 hours, she experienced periods of complete AV block with a ventricular escape rhythm in the 20s.

Does this T wave pattern mean anything?

Dr. Smith's ECG Blog

An Initial ECG was performed: Initial ECG: Sinus tachycardia with prolonged QT interval (QTc of 534 ms by Bazett). She was admitted to the ICU where subsequent ECGs were performed: ECG at 12 hours QTc prolongation, resolution of T wave alternans ECG at 24 hours Sinus tachycardia with normalized QTc interval. No ischemic ST changes.

Wide complex tachycardia and hypotension in a 50-something with h/o cardiomyopathy -- what is it?

Dr. Smith's ECG Blog

A 50-something male with unspecified history of cardiomyopathy presented in diabetic ketoacidosis (without significant hyperkalemia) with a wide complex tachycardia and hypotension. Analysis: there is a wide complex tachycardia. This was the interpretation I put into the system: WIDE COMPLEX TACHYCARDIA. It is regular.
