The number of pacemaker implantations and the incidence of conduction disturbance were both greater in males. Correspondingly, first implantations were carried out at a slightly younger age in males. The age decade during which the greatest number of pacemaker implantations was carried out was the 70s, followed by the 80s. Age was one of the factors that influenced the suitability of the pacing mode. In a significant percentage of patients, the pacing mode was inappropriate. The use of activefixation electrodes continues to increase.
