Exercise Stress<unk>  is the primary diagnostic test and the most helpful clinical tool in diagnosing CPVT as it can reproducibly evoke the typical<unk>  tachycardia during acute adrenergic activation (exercise). During exercise stress<unk> , sinus rhythm accelerates and beyond a heart rate of 120-130 beats per minute, isolated and often monomorphic<unk>  premature beats (VPBs) typically occur first and then increase with heart rate to bigeminy. Subsequently, the VPBs become<unk>  or bidircetional, and as the exercise increase, they form bursts of non-sustained<unk><unk>  tachycardia or bidirectional<unk>  tachycardia (VT). With continuous activity, the arrhythmia persists and becomes more rapid, eventually assuming the appearance of<unk><unk>  tachycardia (VT), which is very fast, fibrillation-like and leads to syncope. The arrhythmias disappear on stopping the exercise. Bidirectional<unk>  tachycardia (VT) is the hallmark finding of catecholaminergic<unk><unk>  tachycardia.
