Beta‐blockers vs control—non‐cardiac surgery

Ventricular arrhythmias—non‐cardiac surgery ECG · patients with conditions requiring non‐cardiac surgery

Beta‐blocker showed no clear difference in ventricular arrhythmias—non‐cardiac surgery ECG compared with control—non‐cardiac surgery (moderate certainty).

Beta‐blockers vs control—non‐cardiac surgery

All supraventricular arrhythmias—non‐cardiac surgery ECG · patients with conditions requiring non‐cardiac surgery

Beta‐blocker leads to lower all supraventricular arrhythmias—non‐cardiac surgery ECG compared with control—non‐cardiac surgery (high certainty).

Beta‐blockers vs control—cardiac surgery

Ventricular arrhythmias—cardiac surgery ECG · patients with coronary heart disease and/or valvular heart disease

Beta‐blocker probably leads to lower ventricular arrhythmias—cardiac surgery ECG compared with control—cardiac surgery (moderate certainty).

Perioperative beta‐blockers vs placebo or usual care

Ventricular arrhythmias (within 30 days) · adults undergoing non‐cardiac surgery under general anaesthesia (to include: low‐risk, medium‐risk, and high‐risk surgeries)

It is very uncertain whether perioperative beta‐blockers changes ventricular arrhythmias (within 30 days) compared with placebo or standard care (very low certainty).
