Follow up (years)	3.91 ± 1.29	3.90 ± 1.37	3.92 ± 1.27

AF Atrial Fibrillation, NSVT Non sustained ventricular tachycardia, VT Ventricular tachycardia, VEB Ventricular ectopic beat
^*The composite endpoint of post-operative ventricular arrhythmia included VT on inpatient telemetry, VT or frequent ventricular ectopy on outpatient Holter, VT on device interrogation and in hospital cardiac arrest
^**The composite endpoint of clinically relevant ventricular arrhythmia included VT on telemetry requiring initiation of antiarrhythmic therapy, sustained VT (> 30 s) on telemetry, non-sustained VT > 10 s on device interrogation and in-hospital cardiac arrest
