T wave alternans refers to the variation of the T wave amplitude on an ECG on a beat-to-beat basis. Having significant T wave alternans is thought to increase the risk of ventricular arrhythmias and ...

This is a challenging ECG in regards to determining if the wide QRS complex rhythm is from ventricular tachycardia or "SVT with aberrancy" such as AV nodal reentry tachycardia causing a rate-dependent ...

Narrow-complex tachyarrhythmias are rapid heart rhythms originating in the upper heart chambers, characterized by a QRS duration of less than 120 milliseconds on an EKG. These arrhythmias can be ...

A heart arrhythmia is when your heart beats too fast, too slow, or out of sync. Some arrhythmias can be genetic. A genetic arrhythmia happens when one or both of your parents pass down a gene change ...
