既往认为高血压病心脏改变主要是由于血压长期升高增加了左心室的负荷,左心室因代偿而逐渐肥厚扩张,形成了高血压性心脏病.认为主要是压力负荷过重的机械因素引起的心脏形态改变,而本身引起的心律失常少见.最近研究证明,高血压性心脏病可由各种综合因素引起心肌病变,使心肌细胞变性或死亡,致心室舒张和收缩功能障碍,因此同样可引起各种心律失常甚至猝死.本文对110例高血压病合并左室肥厚及98例高血压病而无左室肥厚者进行了动态心电图监测,结果表明左室肥厚(left Ventricular hypertrophy,LVH)组心律失常的发生率大大增高.这提示临床医生应高度警惕左室肥厚的危害,注意降压药物的合理选择,现分析报告如下:
Previously thought that the heart of hypertension is mainly due to long-term increase in blood pressure increased left ventricular load, left ventricular hypertrophy due to expansion and expansion, the formation of hypertensive heart disease.Considering the main stress overload caused by mechanical factors Of the heart shape changes, and their own arrhythmia is rare.Recent studies have shown that hypertensive heart disease can be caused by a variety of synthetic factors of myocardial disease, myocardial cell degeneration or death, resulting in ventricular diastolic and systolic dysfunction, it can also cause All kinds of arrhythmia and even sudden death.In this paper, 110 cases of hypertensive patients with left ventricular hypertrophy and 98 cases of hypertensive patients without left ventricular hypertrophy were monitored by dynamic electrocardiogram, the results show that left ventricular hypertrophy (LVH) The incidence of maladjustment greatly increased.This prompted clinicians should be highly vigilant against the hazards of left ventricular hypertrophy, pay attention to the rational choice of antihypertensive drugs, the analysis report is as follows:
