Implantation of devices that can terminate cardiac arrhythmias has increased rapidly over recent years. This article looks at the evidence base for using such devices in the primary and secondary prevention of sudden arrhythmic death, discusses who should have a device and examines the issues surrounding implantation. Recent advances in technology and the future direction of therapy are also reviewed.
