[A regional experience with permanent cardiac pacing: in Friuli-Venezia Giulia the highest density of pacemaker patients in Italy, to-day (author's transl)]

Abstract

In Friuli-Venezia Giulia, a region of 1,243,463 inhabitants, a total of 1,629 first implants have been carried out since the first patient was treated with permanent cardiac pacing (P.C.P.) early in 1692. This patient is still alive. In the last four years, the annual rate of implants was 185 per million inhabitants. The average age of patients is 72.9. The most frequent indication for pacing is the a-v block (64.5%), followed by the fascicular blocks (10.8%) and the sick sinus syndrome. No asinchronous fixed rate generators are implanted at present; lithium batteries are the power source of choice to-day. There have been 1,120 replacements in the Region, mainly due to battery depletion (89.9% of cases). A total of 442 patient deaths have occurred in 10 years due to neoplasms (17%), cerebrovascular accidents (15.6%), respiratory infections (15%), myocardial infarction (8%) and other causes. In 8.8% of cases the death was sudden. There are 1,179 patients in follow-up in the Region (948 per million inhabitants). A computer system, described elsewhere in these proceedings, allows a close follow-up of these patients along with the evaluation of long term pacing on a reliable statistical basis.
