The relation between distribution patterns of ventricular premature complexes (VPCs) and heart rate in Holter recordings abundant in VPCs was analyzed using computer-assisted determination of the number of interectopic sinus beats at different heart rates. Within the complete 24-hour heart rate spectrum, zones were demonstrated that were characterized by manifest or concealed bigeminy or manifest or concealed trigeminy. Bigeminy zones were found in 26 and trigeminy zones in 21 of 42 patients. Bigeminy zones were found at a significantly lower heart rate, on the average, then trigeminy zones. In 10 patients both bigeminy and trigeminy zones were observed. Bigeminy and trigeminy zones probably correspond to the distribution patterns of VPCs predicted from modulation of a pacemaker and reflected reentry, both of which can be induced by electrotonically mediated impulses across a zone of impaired conduction in isolated bundles of Purkinje fibers. The bigeminy and trigeminy zones will correspond at least partly to the entrainment zones found during electrotonic modulation of parasystolic foci. The bigeminy zones will correspond to 2:1 entrainment and the trigeminy zones mainly to 3:1 entrainment.
利用计算机辅助测定不同心率下异位窦性搏动的数量，分析了动态心电图记录中室性早搏（VPC）分布模式与心率之间的关系。在完整的24小时心率谱中，发现了以显性或隐匿性二联律或显性或隐匿性三联律为特征的区域。42例患者中，26例发现有二联律区域，21例发现有三联律区域。平均而言，二联律区域的心率明显低于三联律区域。10例患者同时观察到二联律和三联律区域。二联律和三联律区域可能分别对应于由起搏器调制预测并反映折返的室性早搏分布模式，这两种情况都可由通过浦肯野纤维孤立束中传导受损区域的电紧张介导冲动诱发。二联律和三联律区域至少部分对应于并行心律灶电紧张调制期间发现的拖带区域。二联律区域对应于2:1拖带，三联律区域主要对应于3:1拖带。
