Here is her post-cardioversion ECG: ECG#2 - Immediately post cardioversion: Appropriate ST depression maximal in V5-6 and lead II, secondary to subendocardial ischemia, likely residual from the preceding tachycardia. Patient was referred to electrophysiologic testing due to suspicion of afib and WPW. She was sedated and cardioverted.

Admission and referral to electrophysiology is always indicated. NOTE #3: In the context of a long QTc or ischemia — the finding of ST segment and/or T wave alternans may predict the occurrence of malignant ventricular arrhythmias. In this case, it was able to conduct at a rate of 257 (down the AV node, then up the bypass tract) 6.

These include ( among others ) — acute febrile illness — variations in autonomic tone — hypothermia — ischemia-infarction — malignant arrhythmias — cardiac arrest — and especially Hyperkalemia.

This is mainly to account for the individual variation in anatomical location of right ventricular outflow tract, the main location of electrophysiological abnormalities in Brugada syndrome. Opinion is divided on the need for electrophysiology study.

In most cases, rather, the culprit is gross ischemia due to myocardial infarction, cardiomyopathy, or advanced coronary artery disease. A case for pleomorphism Josephson elucidated the concept of pleomorphism during electrophysiological study of patients with recurrent, sustained ventricular tachycardia. 2] Viskin, S., 8] Liu, E.,

Such findings would normally suggest primary ischemia with concomitant surveillance of coronary occlusion, but these ST/T changes might very well be secondary to the Escape mechanism at hand.

If there is polymorphic VT with a long QT on the baseline ECG, then generally we call that Torsades, but Non-Torsades Polymorphic VT can result from ischemia alone. I have read articles that say that patients without ischemia are at low risk of complications from hypokalemia, But it is not entirely without risk.

For right or wrong reasons, the world of electrophysiology has pushed us into a belief system that, if it is AF, the culprit must be pulmonary veins. In fact, non-pulmonary vein origins can be a staggering 70% in some series. There are innumerable patients who develop de-novo AF without any focus. Reference 1. Francis Marchlinski Cory M.

No evidence for ischemia jumps out. Frick there is a lot going on in today's initial ECG , that I've reproduced in Figure-1: Given that today's patient presented with active CP ( C hest P ain ) high priority must be given to assessing for ECG signs of ischemia. He said he had had three episodes of chest pain that day while urinating.
