Abstract

Since May 1975, we have followed one handred and eighty-two lithium powered pacemakers up.
Eleven generators were removed prematurely because of the pacemaker failure including the ealy exhaution of the battery or the circuit failure.
Signs of the pacemaker failure were the decrease in pacing rate (two cases), the irregularity of spike interval and width (five cases), the oversensing (two cases), and the loss of spike (two cases).
Nine of them were seen in the same model of generators in which the battery depleted during the period from 3 to 3.5 years after implantation.
