摘要
目的:研究老年高血压病并发无症状心肌缺血患者心律失常的特点。方法:24h12导联同步动态心电图检测的老年高血压病并发无症状心肌缺血患者(Ⅰ组)62例,单纯高血压病老年患者(Ⅱ组)76例,正常老年对照者(Ⅲ组)60例,对比3组心律失常发生情况,并分析房性早搏和室性早搏的发生部位,比较3组的窦性心率震荡指标震荡起始(TO)和震荡斜率(TS)。结果:3组房性心律失常发生率差异有统计学意义(P<0.05),但房性早搏发生部位差异不具有统计学意义(P=0.991);室性心律失常发生率及发生部位差异均有统计学意义(P<0.05)。3组TO、TS比较,差异有统计学意义(F=20.211、6.038,P均<0.05),Ⅰ组TO、TS绝对值均大于Ⅱ组和Ⅲ组。结论:无症状心肌缺血是老年高血压病患者发生恶性心律失常的高危因素。
Aim:To study the feature of arrhythmia in old hypertension patients with silent myocardial ischemia.Methods:The data obtained by 24 h 12-leads dynamic electrocardiogram for 62 cases of old hypertension patients with silent myocardial ischemia (group Ⅰ),76 cases of old hypertension patients without silent myocardial ischemia (group Ⅱ) and 60 cases of old healthy people (group Ⅲ) were analyzed.Results:There was significant difference in the incidence of auricular arrhythmia among the 3 groups(P0.05),but not in the original positions where the auricular premature beats occurred(P=0.991).There was significant difference in the incidence of ventricular arrhythmia among the 3 groups(P0.05) and in the original positions where the ventricular premature beats occurred(P0.05).There was significant difference in turbulence onset and turbulence slope among the 3 groups(F=20.211,6.038,P0.05),and those of group Ⅰ were higher than those of group Ⅱ and Ⅲ(P0.05).Conclusion:Silent myocardial ischemia is the risk of bad arrhythmia in old hypertension patients.
