To assess the function of the sino-atrial node, electrophysiological study with pharmacological autonomic blockade was performed in 3 groups of patients: group I with a-v III zero or II zero type 2 heart block, group II with bifascicular interventricular blocks and group III-controls. Sino-atrial node electrogram was recorded in 81% of patients. Obtained results show, that sino-atrial node dysfunction is uncommon in patients with atrioventricular or interventricular blocks (8.6% and 15% respectively). Electrophysiological assessment of sino-atrial node function seems to be important in the consideration of patients with a-v or interventricular blocks for appropriate type of permanent pacing.
为评估窦房结功能，对3组患者进行了药理学自主神经阻滞的电生理研究：第一组为房室Ⅲ度或Ⅱ度2型心脏传导阻滞患者，第二组为双分支室内传导阻滞患者，第三组为对照组。81%的患者记录到了窦房结电图。所得结果表明，房室传导阻滞或室内传导阻滞患者中窦房结功能障碍并不常见（分别为8.6%和15%）。在考虑为房室传导阻滞或室内传导阻滞患者选择合适类型的永久起搏时，窦房结功能的电生理评估似乎很重要。
