Abstract
Two miniature" models of the demand pacemaker were tested in 10 patients with intermittent complete A-V [atrio-ventricular] block. Right ventricular endocardial pacing was performed for 2-10 days. Isoprenaline was infused when complete heart block existed during the testing period. Artificial pacemaker stimulus stopped when the natural rate exceeded the preset one. Pacing renewed when the natural rate became slower than that of the artificial unit. In the presence of sinus rhythm, pacemaker activity was exposed by neurogenic slowing of the sino-atrial node. Rapid scanning monitoring for 20 hr. was useful in testing the intermittent features of the pacemaker.This publication has 17 references indexed in Scilit:
