心律失常为什么常发生于老年人

来源:华人健康网 | 发布时间:2011-02-11 13:48:31 | www.chinesejk.com

  心律失常常发生于老年人,这和老年人心脏的“内忧外患”有关。

  引起老年人心律失常最常见的“内忧”是冠心病、高血压病、心肌病、心力衰竭等,这些病变几乎占了老年人心律失常原因的三分之二;“外患”则指老年人的急慢性肺部疾病如肺气肿、情绪变化如精神焦虑、过度兴奋与悲伤、全身感染和中毒、贫血、电解质紊乱、呕吐以及体液平衡失调,某些药物如洋地黄、利尿剂等。虽然这些“内外忧患”所致的心律失常在青年人也可见,但在老年人中出现的频率高得多。

  除上述“内忧外患”外,老年人心律失常的基本原因还包括年龄增长、心肌纤维的老化、变性,窦房结冲动功能低下等。
