摘要
目的：探讨老年人无症状心肌缺血和心律失常的发生情况和相互关系。方法：回顾性分析１９９６年９月至１９９７年１２月２００例老年患者临床情况和 ２４ ｈ动态心电图资料。结果：几乎所有老年心脏病患者均有窦性心动过缓和房性期前收缩，偶发室性期前收缩和传导阻滞发生率高达６６％和３７％。无症状心肌缺血发生率达１１％，其中以Ⅲ型ＳＴ段压低幅度最大，持续时间最长。 ６７％患者可见心律失常和心肌缺血常互为因果。结论：动态心电图监测可早期发现老年人心律失常和无症状心肌缺血存在，有助于老年冠心病的及早检出，对避免和减少心肌梗死和猝死的危险性具有重要意义。
Objective: To study the relationship between silent myocardial ischemia and arrhythmia in the elderly. Methods: We analysed the clinical and dynamic ECG monitoring data of 200 cases from Sept. 1996 to Dec. 1997 retrospectively. Results: Almost all of the old patients with heart diseases had sinus bradycardia and atrial premature beats. Ventricular premature beats and conductive block were 66 % and 37 % respectively. 11 % patients had silent ischemia. Among various silent ischemia, ST Segment depression in Ⅲ pattern was most severe. There was closely relationship between arrhythmia and myocardial ischemia. Conclusion: The dynamic ECG monitoring can early detect whether the old patients have arrhythmia and silent myocardial ischemia. It could early checkout the old patients with coronary heart diseases, decrease the risk of myocardial infarction and sudden death.
