[Determination of thresholds of external cardiac pacing during anesthesia].
The efficacy of transcutaneous pacing was studied in 33 patients during general anaesthesia. The temporary pacing was effective in all cases. Stimulation thresholds ranged from 85 to 150 mA (mean : 110 +/- 17). In all 33 patients, external pacing was effective in producing a pulse without significantly reducing arterial pressure. Stimulation thresholds were only influenced by electrode position; age, weight, thoracic diameter and cardiothoracic ratio did not have any effect on them. No adverse effects of transcutaneous pacing were recorded. Transcutaneous pacing can be an alternative to transvenous right ventricular endocardiac pacing in the operating room in some circumstances.
