Device management. VT = ventricular tachycardia; VF = ventricular fibrillation; ATP = anti-tachycardia pacing; CL = cycle length.

Recommendations – Device Management	Class	Level	Ref.
Detection time should be programmed to the longest possible value and detection cycle length programmed to the shortest possible value, with the aim to reduce unnecessary shocks.	I	A	[38], [39], [42]
In sustained monomorphic VTs, primary ATP delivery (preferentially burst pacing at ≥ 80% CL) should be considered and the device reprogrammed accordingly.	IIa	A	[38], [39], [42], [43], [44], [45]
To minimize the occurrence of VT / VF triggers (e.g. bradycardia, long QT, short coupled VPBs), pacing at an increased lower rate may be considered.	IIb	C	[4]
