ECG Disease Patterns ECG Disease Patterns Bookmark Share The electrocardiogram can be used to diagnose a wide variety of cardiac and non-cardiac conditions. Suspicion for long-standing pulmonary disease (with possible RVH/pulmonary hypertension) should, therefore, be raised by the combined ECG findings of rightward axis, incomplete RBBB, low voltage in several precordial leads, and persistent precordial S waves in leads V4, V5, V6even in the absence of a tall R wave in lead V1 and ECG criteria for right atrial enlargement.
