目的 :为探讨老年心脏瓣膜钙化与心肌缺血及室性心律失常的关系。方法 :用 2 4小时动态心电图检测经心脏彩超检查确诊的老年心瓣膜钙化体高血压病 3 4例 ,无钙化者 64例的ST段缺血性压低及室性心律失常。结果 :钙化组缺血性ST段压低 ,总室性心律失常及LⅢ 以上复杂心律失常发生率与无钙化组比较分别为 67 65%、85%及 52 9%。比 1 0 93 %、64 1 %及 1 7 1 9%(P <0 0 0 1 ,P <0 0 5及P <0 0 0 1 )。结论 :老年高血压病伴心瓣膜钙化可作为临床诊断冠心病的一个重要参考依据。
Objective: To investigate the relationship between elderly heart valve calcification and myocardial ischemia and ventricular arrhythmia. Methods: 24 hours ambulatory electrocardiography was used to detect the ST-segment ischemic depression and ventricular arrhythmia in 34 elderly patients with valvular heart disease and 64 patients without calcification. Results: The ischemic ST segment depression, total ventricular arrhythmia, and the incidence of complex arrhythmia with L Ⅲ or more were 67 65%, 85% and 52 9% respectively in the calcification group. (93%), 64% (1%), and 17.1% (P <0.01), P <0.05 and P <0.01. Conclusion: Elderly hypertensive patients with cardiac valve calcification can be used as an important reference for clinical diagnosis of coronary heart disease.
