近年来,临床上发现病窦综合征并不少见,老年、青年及儿童均可发生,而且是安装永久性人工心脏起搏器的最主要指征,因此颇受重视。病窦综合征比较复杂,目前对其病因认识,临床表现,诊断条件及治疗方法等都还存在一定问题,有待进一步探讨和解决。 一、病因 由迷走神经机能亢进、血钾过高、洋地黄或奎尼丁过量,以及应用β受体阻滞药等所致窦房结功能障碍是可逆的,不属于病窦综合征。由于病理解剖病例为数较少,对其病理本质了解仍不多,病因仍须作更多研究。可引起病窦综合征的病因如下:(1)窦房结退行性病变(纤维化),(2)冠
In recent years, clinically found sick sinus syndrome is not uncommon, elderly, young and children can occur, and is the most important indication of the installation of permanent artificial cardiac pacemaker, so much attention. Sick sinus syndrome is more complex, the current understanding of its causes, clinical manifestations, diagnostic conditions and treatment methods are still some problems to be further explored and resolved. First, the etiology of the vagus nerve hyperthyroidism, hyperkalemia, digitalis or quinidine overdose, and the application of β-blockers and other sinus node dysfunction caused by is reversible, do not belong to sick sinus syndrome. Due to the small number of pathological anatomy, the pathological nature of their understanding is still small, the cause still needs more research. Causes of sick sinus syndrome are as follows: (1) sinus node degeneration (fibrosis), (2) crown
