Familial history of RVD/C or premature sudden death | |
---|---|
Clinical presentation | |
Ventricular arrhythmias (sometimes sudden death) | |
Right congestive heart failure | |
Supraventricular arrhythmias | |
Asymptomatic with abnormal ECG, chest x ray, or echocardiography | |
No specific physical findings (widely split II heart sound) | |
ECG abnormalities | |
T wave inversion on right precordial leads | |
ε waves (late potentials) | |
Prolonged QRS duration on V1–V2 | |
Characteristics of ventricular arrhythmias | |
Frequently with LBBB pattern (right ventricular origin) | |
Wide range of severity (from patient to patient and during the course of disease) from sustained or non-sustained VT (rarely VF), to ventricular ectopic beats |
LBBB, left bundle branch block; VT, ventricular tachycardia; VF, ventricular fibrillation.
