  • Title: Atrial arrhythmias post coronary bypass grafting.
    Author: Chew JT, Ong KK.
    Journal: Singapore Med J; 1993 Oct; 34(5):430-4. PubMed ID: 8153692.
    Abstract:
    Atrial arrhythmia is a relatively common complication post coronary bypass grafting. A retrospective study of 400 patients who had undergone coronary arterial bypass grafting over a period from June 1989 to December 1990 were studied to determine the incidence of atrial arrhythmias in an Asian population. The incidence of atrial arrhythmias post coronary artery bypass grafting was 14.25% (57 out of 400 patients). The commonest type of atrial arrhythmia was atrial fibrillation (82.5%), followed by supraventricular tachyarrhythmia (14.0%) and atrial flutter (3.5%). The preoperative state of the myocardium, intra-operative ischaemia to the myocardium and hypokalemia were found to be the possible contributory factors to the development of atrial arrhythmias.
