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 V 4, V 5, V 6 even in the absence of a tall R wave in lead V 1 and ECG criteria LBBB. It not only blocks blood flow in the lungs, but it can affect heart function by making the right side of the heart work harder than usual.

In bundle branch block, the QRS complexthe portion of the ECG that represents the electrical impulse traveling across the ventriclesis wider than normal, since it takes longer than normal for the impulse to be distributed. Pulmonary heart disease, also known as cor pulmonale, is the enlargement and failure of the right ventricle of the heart as a response to increased vascular resistance (such as from pulmonic stenosis) or high blood pressure in the lungs..
