[Swiss statistics on the use of cardiac pacemakers in 1986]

The 1986 annual pacemaker survey covers the data from all centers implanting cardiac pacemakers in Switzerland. The number of centres has increased from 34 to 36 while the number of first implants remains unchanged with 226 per million population. Clinical indications, ECG indications and etiology have undergone no significant changes in the last 3 years. Within the pacing system used, however, 13% of VVI pacemakers were now rate responsive, whereas the percentage of physiological pacemakers remained unchanged at 7%.
