Endocardial pacing electrode design and rate of displacement.

Abstract

In a series of 184 patients with a permanent endocardial pacing system the rate of electrode displacement was 3-0 per cent using the Devices L120SR electrode, and 23-1 per cent using the Devices S120 electrode. The technique and pacing team were unchanged during the period of study. It is suggested that the design and mechanical characteristics of the elctrodes were responsible.
