Extreme QT prolongation in elderly women after non-ST elevation myocardial infarct

Abstract

This is a brief report of three cases of non-ST elevation myocardial infarction presenting with giant T wave inversion and prolonged QT interval. Searching the medical literature revealed a handful of similar cases. There were quite a few common characteristics among these cases suggesting an uncommon but distinctive presentation.

Non-ST elevation acute coronary syndromes: timing and selection of early invasive management, ECG monitoring need, DAPT duration, pathogenesis of recurrence and beware of delirium in the intensive/acute cardiac care unit!

“…Some NSTE-ACS patients develop a giant T wave inversion and an extreme QT prolongation when pain free in the subacute phase. 7 Acute cardiac care cardiologists should be familiar with this characteristic ECG pattern.…”
