To evaluate the incidences of and risk factors predisposing to appropriate and inappropriate shocks and mortality in a 'real-world' population of patients with ischaemic heart disease (IHD) and implantable cardioverter defibrillators (ICD) for primary prevention of sudden cardiac death (SCD). ⋯ In this nationwide study of IHD patients with an ICD for primary prevention of SCD, the incidence of appropriate shocks as well as inappropriate shocks were significantly lower than reported in randomized trials. Implantation of a dual-chamber ICD was associated with more inappropriate shocks compared with single chamber devices.
