The function of sinus node (SN) was studied in 101 subjects with intraventricular blocks (IVB) and 30 controls. The patients with IVB showed a significant increase in the corrected time of SN function recovery and that of sinoatrial conduction both before and after medicamentous++ autonomic block, as compared to the controls. In general, signs of SN dysfunction were detected in 47 (46.5%) subjects with IVB. In 18.8% of the examinees, SN dysfunction was due to abnormal autonomic exposures, 27.7% had abnormalities in SN proper or perinodal tissue. ++Tachy-bradycardia was found in 53.5% patients with the sick sinus syndrome and IVB, 25% had concurrent atrioventricular conduction disturbances. A concomitant SN lesion was common in patients with IVB. One should take into account a type of this syndrome and the status of atrioventricular conduction when the optimal conditions of continuous electrical cardiostimulation are applied to patients with IVB and clinical signs of the sick sinus syndrome.
对101例室内传导阻滞（IVB）患者和30例对照者的窦房结（SN）功能进行了研究。与对照组相比，IVB患者在药物性自主神经阻滞前后，SN功能恢复时间和窦房传导时间均显著延长。总体而言，在47例（46.5%）IVB患者中检测到SN功能障碍迹象。在18.8%的受检者中，SN功能障碍是由于自主神经暴露异常，27.7%的患者SN本身或结周组织存在异常。53.5%的病态窦房结综合征合并IVB患者出现心动过速-心动过缓，25%的患者并发房室传导障碍。IVB患者常伴有SN病变。在对伴有病态窦房结综合征临床症状的IVB患者应用持续心脏电刺激的最佳条件时，应考虑该综合征的类型和房室传导状况。
