The ECG in the Figure was obtained from a 78-year-old man with long-standing pulmonary disease and new-onset heart failure. Based on the low voltage in leads V1, V2, V3, the rightward frontal plane axis, incomplete right bundle-branch block, and persistent precordial S waves, the computer interpreted the overall pattern as consistent with pulmonary disease. What else should be added to your interpretation?
