12 >>A 57-year-old patient with a history of dilated cardiomyopathyand an ejection fraction of 20% is admitted to hospital after apresyncopal episode. His ECG on arrival shows monomorphic VTwith a rate of 180 bpm and his BP is 70/50 mmHg. He receivesurgent cardioversion and his QRS complexes are narrow onreturn to sinus rhythm. He is normally NYHA class III and is onmaximum medication for HF. ?
- (A) According to NICE criteria he does not qualify for an ICD as his aetiology is not IHD
- (B) He should receive a biventricular ICD
- (C) He should receive a standard ICD
