Twenty-four male rats that became hypertensive after complete ligature of the abdominal aorta, just above the origin of the left renal artery, showed combined myocardial infarction. To study the electrocardiographic patterns of the experimental right ventricular infarction, the V4R right thoracic lead was recorded at different time intervals after aortic ligature. The patterns recorded were as follows: Q waves in 23 cases (95.8%), ST-T segment elevation in 11 cases (45.8%), ST-T segment depression in two cases (8.3%), and decrease in voltage of R wave in four cases (16.6%), with a predominance of the alterations of the ST-T segment in the acute phase and the appearance of Q waves during the subacute phase.
