This ECG example is a rate dependent right bundle and not a ventricular couplet (two PVCs in a row) due to the QRS morphology. Recall that the Brugada criteria describe a ventricular origin to a ...

Ventricular arrhythmia complexity: couplets with short interectopic interval; NSVT or SVT; short coupling interval (‘R on T’). Ventricular arrhythmia/PVB response to exercise: persistence or increase ...

In addition, ventricular (polymorphic, couplets or non-sustained ventricular tachycardia) or supraventricular tachyarrhythmias (atrial flutter, paroxysmal atrial fibrillation or SVT) were identified ...
