To reduce the number of electrocatheters required for an electrophysiologic study and to facilitate prolonged monitoring of the electrical properties of the heart, an octapolar electrocatheter was designed and tested in 45 consecutive patients undergoing routine electrophysiologic studies. The electrocatheter introduced into the right ventricle served for: (a) right ventricular pacing; (b) recording of low lateral and low septal right atrial electrograms; (c) recording of the His bundle potential in 39 out of the 45 patients (86%); (d) 24-hour monitoring of the AV conduction intervals and refractory periods at the patients' bedsides. The octapolar electrocatheter reduced the number of probes required for studying the mechanisms of reciprocating tachycardia and allowed 24-hour bedside electrophysiologic monitoring.
为减少电生理研究所需的电极导管数量，并便于对心脏电特性进行长时间监测，设计了一种八极电极导管，并在45例接受常规电生理研究的连续患者中进行了测试。引入右心室的电极导管用于：(a)右心室起搏；(b)记录低位侧壁和低位间隔右心房电图；(c)45例患者中的39例（86%）记录希氏束电位；(d)在患者床边对房室传导间期和不应期进行24小时监测。八极电极导管减少了研究折返性心动过速机制所需的探头数量，并允许进行24小时床边电生理监测。
