Interestingly, an electrocardiogram (EKG) revealed macro T-wave alternans (TWA) indicative of a high risk of malignant ventricular arrhythmia in the form of ventricular fibrillation and sudden cardiac death. TWA in JLN syndrome has not been described in the global literature so far. Our case is ...
A repolarisation phenomenon manifesting as a microvolt beat-to-beat change in the amplitude of the T wave and ST segment on EKGs. T-wave alternans has low specificity as a predictor of arrhythmic risk in unselected populations with prior myocardial infarction. Segen's Medical Dictionary. © ...

During ambulatory EKG monitoring, she had two types of T wave alternans (TWA): one occurred during a steady state in which RR intervals remained relatively unchanged (type 1), whereas the other developed during transition from 2:1 AV conduction to 1:1 conduction in which a sudden change in...
