The electrocardiograms of 15 left atrial rhythm and sinusal rhythm patients are studied. The spontaneous occurrence of LAR and the possibility of return to SR by vagal stimulation manoeuvers are reported. The electrocardiographic modifications of the ectopic rhythm are shown and compared either with those of the coronary sinus rhythm or junctional A-V rhythm, or with those of the tracings recorded during atrial pacing. The intermittent occurrence of the LAR in the studied cases is theoretically ascribed to the awakening of an ectopic focus, localized in the left atrium, acting as a new pace-maker because of its excited activity or abnormal depression of the sinus.
对15例左房节律和窦性节律患者的心电图进行了研究。报告了左房节律的自发发生情况以及通过迷走神经刺激操作恢复窦性节律的可能性。展示了异位节律的心电图改变，并将其与冠状窦节律或交界性房室节律的改变进行比较，或与心房起搏时记录的心电图改变进行比较。在所研究的病例中，左房节律的间歇性发生理论上归因于位于左心房的异位起搏点的觉醒，该起搏点由于其兴奋活动或窦房结的异常抑制而充当新的起搏器。
