    Journal: Schweiz Med Wochenschr; 1993 Feb 20; 123(7):297-300. PubMed ID: 8446865.
    Abstract:
    In the annual pacemaker survey covering practically all pacemakers implanted in Switzerland (there have been 50 implanting hospitals in the last three years) the number of first implants increased from 242 per million population in 1989 to 252 in 1991. Clinical indications, ECG-indications and etiology have undergone no significant changes in the last three years. Within the pacing-systems used however there was a marked increase in rate responsive single chamber pacemakers from 25% in 1989 to 34% in 1991. The percentage of double chamber pacemakers however increased gradually from 14% in 1989 to 21% 1991. At the present time there are some 10,000 patients with a cardiac pacemaker in this country.
