Abstract

108 patients operated with various techniques for isolated valvular and/or subvalvular stenosis of the pulmonary artery were studied 10-25 yr after operation from the ECG viewpoint. ECG was found to be changed in 73% of subjects, with a rather higher incidence in those operated on with open heart (79%) and in those subjected to infundibular resection (82%). A high percentage of patients (49%) presented a single ECG change, generally represented by an usually incomplete right branch block, while only in 9% were more than two changes encountered. A 'pulmonary' P was present in 5%. The electrical axis of the heart was directed at about +75% on average: left axial deviation was rare; right axial deviation of more than +110° occurred in 10% of patients. Signs of slight or moderate right ventricular hypertrophy were observed in 18% of the ECGs and were more frequent in patients who had undergone infundibular resection (33%). Changes in the recovery phase were rare and were generally represented by a reversal of the T wave in the right precordials. The most frequent ECG abnormality was right branch block which was seen in 63% of cases (83% in those operated on by infundibular resection) commonly (82%) in incomplete form. The ECG aspects are correlated with clinical and radiological aspects. The pathogenesis of the changes observed is discussed.
