老年患者餐后心肌缺血的动态心电图临床分析

Dynamic electrocardiogram of ischemia after meal in old patients

目的应用动态心电图(DCG)观察老年患者餐后心电图变化,探讨餐后ST改变的原因,及其应用价值。方法对常规12导联心电图检查无心肌缺血改变者,进行24h的DCG检查,分析患者餐后DCG变化。结果老年患者餐后可出现不同程度的心肌缺血。并可表现为胃疼等胃部不适症状,休息或舌下含化硝酸甘油后可迅速缓解。结论餐后心肌缺血是值得老年患者警惕的心血管意外危险因素。

Objective To observe Electrocardiogram changes before and after meal in old patients, study the rea- sons of ST segment changes and its value. Methods Select patients who did not have any ischemia on their 12 lead resting ECG to perform Holter analysis. Analyze the ECG changes before and after meal. Results Old patients had different degrees of ischemia and stomach＇ pain or other symptom which could be alleviated after having rest or sublinguul nitroglycerin. Conclusion The ischemia happening after meal is a risk factor of cardiovascular events for old patients.
