老年人心律失常多见,主要原因是冲动发放功能低下和传导系统的障碍,高龄者其传导系统本身可有器质性改变,这些皆为老年人发生心律失常的基本原因。本文对老年人的病态窦房结综合征、心房颤动及房室传导阻滞三种心律失常,就有关的几个问题进行讨论。一、病态窦房结综合征:病态窦房结综合征在老年人较常见,据报告,60岁以上的病例约占半数以上,其基本原因是随着年龄增长到高龄,窦房结发生器质性的变性改变,P细胞逐渐减少,到75岁以上减少至正常时的10％以下,同时有进行性纤维化。当有慢性窦房传导阻滞时,提示窦房结有广泛性病变,同时房室结也有变性。以往认为上述改变
Arrhythmia more common in the elderly, mainly due to impulse impaired function and conduction system disorders, the elderly may have an organic substance in the conduction system itself, these are the basic causes of arrhythmia in the elderly. In this paper, the elderly sick sick sinus syndrome, atrial fibrillation and atrioventricular block three kinds of arrhythmias, on the several issues discussed. First, sick sinus syndrome: sick sinus syndrome is more common in the elderly, it is reported that more than half of the cases over the age of 60 accounted for more than half of its basic reason is that as age increases to the elderly, sinus node generator Qualitative changes in degeneration, P cells gradually decreased to more than 75 years of age reduced to 10% of normal, accompanied by progressive fibrosis. When there is a chronic sinus node block, suggesting a wide range of sinus node lesions, while also atrioventricular node degeneration. In the past that the above changes
