Right atrial monophasic action potential was recorded using a suction electrode catheter in 20 patients with chronic cor pulmonale. The duration of right atrial monophasic action potential was recorded using suction electrode catheter in 20 patients with chronic corpulmonale. The duration of right atrial monophasic action potential was 397 +/- 17 msec, longer than the normal value of 325 +/- 37 msec found in 30 normal subjects. The conclusion of our work is that the long right atrial monophasic action potential duration may explain the sinus rhythm stability and the rarity of atrial arrhythmias in chronic cor pulmonale.
使用吸引电极导管记录了20例慢性肺心病患者的右心房单相动作电位。使用吸引电极导管记录了20例慢性肺心病患者右心房单相动作电位的持续时间。右心房单相动作电位的持续时间为397±17毫秒，长于30名正常受试者的正常值325±37毫秒。我们研究的结论是，右心房单相动作电位持续时间延长可能解释了慢性肺心病中窦性心律的稳定性和房性心律失常的罕见性。
