Abstract/OtherAbstract:
|
The incidence and significance of postoperative conduction defects after coronary artery bypass surgery were investigated prospectively in 181 patients. Several pre- and perioperative variables, especially the temperature in three regions of the myocardium, were recorded as explanatory variables. The incidence of conduction defect(s) in the immediate postoperative electrocardiogram (ECG) was 55.8%, and 35.9% of the patients had a conduction defect when leaving hospital. Two patients had a permanent third degree atrioventricular (AV) block. Five pacemakers were implanted. Left main coronary artery stenosis was more common (P < 0.01), and the perioperative myocardial temperatures (P < 0.05-0.01) were lower in patients with conduction defects. These patients had also low postoperative cardiac output more often (P < 0.001), their creatine kinase myocardial (MB) fraction values were higher (P < 0.01), and they stayed in hospital longer (P < 0.05). Right bundle branch block had no significant association with the studied variables. |
