aIntraoperative arrhythmias were ventricular or supraventricular changes that occurred with hemodynamic instability, and that required intervention
bHaemodynamic instability was defined as a decrease in systolic blood pressure lower than 90 mmHg, a heart rate lower than 60 beats per minute, or the use of vasopressors or inotropic drugs (intraoperatively use of bolus was not considered as haemodynamic instability criterion)
cDefined as cardiovascular death, acute myocardial infarction, unstable angina, acute pulmonary edema, cardiogenic shock, arrhythmia with hemodynamic instability, pulmonary thromboembolism, stroke, myocardial infarction, and respiratory infection
