Sadowski Z, Szwed H. Inst of Cardiology, Warsaw. PACE 6: Abstract 488. The results of transesophageal ventricular pacing were analyzed in patients with complete atrioventricular block or sinus node disease. Ventricular pacing was performed using bipolar electrodes of our own design in 84 patients with cardiac arrest: 36 women and 48 men, aged 20 to 85 years (mean 66.8 years). Fifty-four patients (Group 1) had the electrodes inserted during resuscitation procedure after cardiac arrest while the remaining 30 patients at high risk of cardiac arrest (Group 2) had the electrodes introduced prophylactically pre-operatively. Pacing was initiated when pauses in the ventricular rhythm appeared and was effective in 48 of 54 pts in Group 1 (88.9%) and in 27 of 30 pts in Group 2 (90%). Patients were paced for 2 to 180 minutes.
