Overview
Catecholaminergic polymorphic ventricular tachycardia patients usually have a normal resting ECG. However, in a subset of patients, sinus bradycardia, prominent U-waves, and supraventricular arrhythmias are seen.
Electrocardiogram
Resting ECG
- CPVT patients usually have a normal resting ECG, and the QT interval is usually not prolonged.[1][2][3]
- However, the following findings maybe seen in a subset of patients:
- Sinus bradycardia, in approximately 20% of patients, as another consequence of the diastolic calcium leakage facilitated by either RyR2 or CASQ2 mutations.[4][5]
- Prominent U-waves, which may also be related to altered intracellular calcium handling; its clinical significance is unknown.[6]
- Supraventricular arrhythmias, including isolated atrial ectopic beats, non-sustained supraventricular tachycardia and bursts of atrial fibrillation, are present in 16-26% of CPVT patients, maybe related to co-existing sinus node dysfunction.[1][7][8][9][10][11][12]
