The occurrence of postoperative supraventricular arrhythmia in off pump coronary artery bypass grafting as a predictor for postoperative morbidity and mortality

Coronary artery bypass grafting (CABG) remains the “gold standard” treatment for multi-vessel coronary artery disease, particularly for three-vessel or left main coronary artery disease. Supraventricular arrhythmias are a group of cardiac arrhythmias that originate at or above the atrioventricular node and have a narrow QRS complex (<120 ms) . Supraventricular arrhythmias include Atrial fibrillation , Atrial flutter , Supraventricular tachycardia including Paroxysmal supraventricular tachycardia (PSVT). Aim of the study is To determine the occurence of morbidity, mortality and number of other risk factors associated in various types of post operative Supraventricular Arrhythmias(SVA) in patients undergoing Off pump CABG.
