Practical cardiac pacing
In this chapter only cardiac pacemakers used for the treatment of bradycardias will be considered. Approximately 10 000 pacemaker implants are performed in the UK each year, which represents approx. 160 implants per million population. This contrasts with considerably higher rates in many other developed countries (USA, Canada and West Germany) of up to 500 per million1. In this country this almost certainly represents under-diagnosis and referral, particularly of patients suffering from sick sinus syndrome and carotid sinus syndrome.
