The significance of bundle branch block in the immediate postoperative electrocardiograms of patients undergoing coronary artery bypass.

Three hundred sixteen consecutive patients undergoing coronary artery bypass were studied for postoperative electrocardiographic conduction disturbances. Fifty-five of these 316 patients had postoperative bundle branch block (Group 1). This group had a higher incidence of left main coronary stenosis, together with previous inferior myocardial infarction, than patients without postoperative conduction disturbances (Group 2). Perioperative myocardial infarction, low cardiac output, and death were significantly more common in Group 1 than in Group 2: 7.3% versus 1.9% for perioperative myocardial infarction, 16.4% versus 2.7% for low cardiac output, and 5.5% versus 0.8% for death. Analysis of the type of conduction disturbances indicates that the presence of a new complete left bundle branch block postoperatively in a patient undergoing coronary artery bypass is a sign of intraoperative myocardial damage. This damage is potentially lethal, especially in a patient with left main coronary stenosis and previous inferior myocardial infarction.

Successful repair of concomitant tear of the interventricular septum and right ventricular free wall after acute myocardial infarction.

Early repair of acute rupture of the ventricular septum after myocardial infarction is now the procedure of choice accepted by most centers. Rupture of the right ventricular free wall is rare and usually is accompanied by tamponade. The finding of coincidental right ventricular free wall rupture and acute ventricular septal defect following myocardial infarction and their successful repair are discussed in the following report.

Injected progestogen and lactation.

Norethisterone ethanate (200 mg every 84 days) and medroxyprogesterone acetate (150 mg every three months) were found to be completely effective in fertility control when started in the puerperium. Neither agent had any ill effect on the amount of milk or the duration of lactation. From the third month onward the three-hourly available milk and the infant weight gain per month were statistically higher in treated groups than in controls. Milk proteins showed a slight decrease in most groups, including the controls, owing to the low-protein diet.No important side effect was produced by these agents other than amenorrhoea.
