The Frequency of New Permanent Pacemaker Implantations in 1975, 1980 and 1990 A Model Study Taking into Account the Dependence of Age and Sex

Statistics of the number of new, permanent pacemaker systems per year have been obtained for various countries since the end of the 1960s. These figures have been expressed mostly as the number of new paced patients per million inhabitants. There is a progressive increase in the need of a pacemaker with increasing age. Demographic data show considerable differences in the number of elderly in the various countries. More pacemakers have been implanted in males than in females, The predicted number of new permanent pacemaker systems in 1960 and 1990 has been calculated for eleven countries and has been estimated to be 200 per million inhabitants of the total population (age and sex distributions in the populations have been taken into account). Considerable differences appear.
