Ventriculo-atrial conduction was studied by ventricular pacing in three groups of patients: 34 cases with the preexcitation syndrome on surface ECG, 35 cases with documented paroxysmal atrial tachycardia but with otherwise normal ECGs and 120 cases without either of these two conditions. This conduction time was unchanged up to pacing rates of over 160/min in 88 p. 100 cases with preexcitation and was thus a sign of a nodal short-circuit. This phenomenon was also observed in 85 p. 100 cases with isolated paroxysmal atrial tachycardia and in 20 p. 100 normal cases which suggests the presence of a latent accessory pathway in these patients.
通过心室起搏对三组患者的心室-心房传导进行了研究：34例体表心电图有预激综合征的患者、35例有记录的阵发性房性心动过速但心电图其他方面正常的患者以及120例无上述两种情况的患者。在88%（100例中有88例）有预激的患者中，直至起搏频率超过160次/分钟时，这种传导时间均无变化，因此这是一种结性短路的征象。在85%（100例中有85例）孤立性阵发性房性心动过速的患者以及20%（100例中有20例）正常患者中也观察到了这种现象，这提示这些患者存在潜在的附加通路。
