Clinical and ECG findings useful for diagnosing right ventricular dysplasia/cardiomyopathy (RVD/C)
| 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.
