摘要

阿托品和心得安阻断了交感神经和副交感神经的心脏作用。在给药前后测定内禀心率(IHR)和快速心房起搏(RAP)。检查了两种情况下的主要和次要后起搏参数。根据《国际卫生条例》对正常(31例)和病理(20例)进行区分。在自主神经阻断后的第二阶段(PPC 2-10),绝大多数IHR正常病例恢复到基本频率呈指数特征。异常可能出现在初级和次级阶段。它们有不同的类型:一种是关于恢复时间;另一种电生理异常发生在药理学神经切开术后没有恢复到驱动前的正常周期长度。第二阶段可出现耳窦阻滞。它们可能依赖于或独立于植物神经系统的作用而出现。新的测试允许正常和病理窦结功能的生理病理分类。

Electrophysiological classification of normal and pathological sinus node function.

The sympathetic and parasympathetic neurological cardiac effects were blocked with atropine and propranolol. The intrinsic heart rate (IHR) was determined and rapid atrial pacing (RAP) was carried out before and after administration of the drugs. The primary and secondary postpacing parameters were examined in both circumstances. Normal (n = 31) and pathological (n = 20) cases were differentiated on the basis of the IHR. In the secondary phase (PPC 2-10) after autonomic blockade returned to the basic frequency was of exponential character in the great majority of normal IHR cases. Anomalies may appear in both the primary and secondary phases. They are of different types: one of them concerns the recovery time; another electrophysiological anomaly occurs when there is no return to the predrive normal cycle length after pharmacological neurotomy. In the secondary phase there may appear sinoauricular blocks. They may depend on or appear independently of the effect of the vegetative nervous system. The new test allows a physiopathological classification of normal and pathological sinus node function.
