Thomas M. Roston, MD, FRCPC from The University of British Columbia speaks about Burst Exercise Testing Can Unmask Arrhythmias in Patients With Incompletely Penetrant Catecholaminergic Polymorphic Ventricular Tachycardia.

Synopsis:

Cardiac arrest following abrupt exercise is a symptom of catecholaminergic polymorphic ventricular tachycardia (CPVT). Standard exercise stress testing (EST), on the other hand, is insensitive, resulting in misdiagnosis and undertreatment. We report on six patients who had a unique burst exercise test, which was characterized by a sudden high workload at the start of testing, after a nondiagnostic conventional progressive EST. Compared to conventional EST, burst EST caused new and more complicated arrhythmias in 5 of 6 patients, necessitating medication treatment in 3 individuals. This minor EST adjustment might increase diagnostic sensitivity and treatment decision-making by better mimicking a common CPVT triggering event.
