ABSTRACT

Objective. To asess the kind of arrhythmias in the immediate postoperative of patients undergoing cardiac surgery.
Design. Case series, prospective study.
Setting. A cardiac surgery intensive care unit of México City.
Patients and methods. One hundred seven patients undergoing cardiac surgery: A) cardiac valvular surgery (n = 54), B) coronary artery bypass (n = 31), C) repair of atrial septal defects of the secundum type (n = 17), D) others (n= 6).
Interventions. Continuous electrocardiographic cardiac monitoring during the first 24 hours after cardiac surgery.
Measurements and main results. Patients of group A had premature ventricular contractions, PVCs, (49%), supraventricular premature contractions, SPVCs, 39.9%, and third degree AV block (3.7%). In group B PVCs (45.6%), SPVCs (38.8%) and third degree AV block (9.7%) were observed. PVCs (5.9%), SPVCs (5.9%) and third degree AV block were present in patients of group C. In group D we detected only bigemini (33.33%). Seven patients died in group A, four in group B and one in group D.
Conclusion. PVCs, SPVCs and third degree AV block were the arrhythmias more frequently observed in the immediate postoperative of cardiac surgery.
