Abstract

We present the case of a relative of a patient with catecholaminergic polymorphic ventricular tachycardia. This relative underwent a standard (Bruce) exercise stress test (EST), which had normal results. He then underwent our modified "sprint" EST, with positive results. This report underlines how the sprint EST may provoke arrhythmias better than the standard Bruce EST. (Level of Difficulty: Advanced.).
