Miscellaneous ECG 34
- Normal sinus rhythm
- Isolated posterior wall hypertrophy
Without the clinical history this diagnosis is impossible to make based on the ECG alone. This ECG was from a patient with Duchenne's Muscular Dystrophy who had posterior wall hypertrophy confirmed on an echocardiogram. This is one of the causes of an R:S ratio > 1 in lead V1. Other causes of a large R wave in lead V1 include a right bundle branch block, WPW Type A, right ventricular hypertrophy and a posterior wall myocardial infarction.
