Key result
ICD implantation rates varied across Western Europe and negatively correlated with amiodarone use (r = -0.66, P = 0.02), while patient age at implantation increased from 1993 to 1998 (P < 0.001).

ICD implantation rates in Western Europe between 1993 and 1998 varied widely and were inversely correlated with amiodarone use, rather than being driven by healthcare expenditure.
Copie et al. (2000) conducted an observational in High risk of sudden cardiac death (n=2,257). Implantable cardioverter defibrillators (ICDs) was evaluated on Temporal and geographical trends in ICD implantations (r = -0.66, p=0.02). ICD implantation rates varied across Western Europe and negatively correlated with amiodarone use (r = -0.66, P = 0.02), while patient age at implantation increased from 1993 to 1998 (P < 0.001).
