Electrocardiographic J waves as a hyperacute sign of Takotsubo syndrome

Abstract

Typical electrocardiographic (ECG) signs of acute Takotsubo syndrome (TTS) consist of ST-segment elevation and/or T wave inversion. We report an unusual case of a 62-year-old woman with TTS who acutely exhibited on 12-lead ECG transient J waves preceding ST-T abnormalities. In the experimental model of myocardial ischemia, the appearance of J waves represents an early ECG abnormality and is followed by ST-segment elevation. Because of the similar ECG time course observed in TTS and myocardial ischemia, we speculate that common electrophysiologic mechanisms may account for J waves appearance in these 2 clinical conditions. Our case report shows that recording of ECG J waves in postmenopausal women presenting for acute chest pain may be a sign of an ongoing TTS and suggests a similarity to myocardial ischemia as the pathologic basis.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
