PULMONARY DISEASE PATTERN: ECG changes commonly associated with pulmonary diseases such as COPD. 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 Twitter: @rob_buttner. Although the ST-T wave changes in the inferior leads of the tracing seen here may indeed reflect right-sided "strain" (from RVH), it is important to emphasize that these changes also could reflect ischemia.
