350例老年心脏病患者24h 动态心电图(DCG)监测与自身ECG 检查结果作对比分析,显示:DCG 对心律失常的检出率82.3%明显高于ECG 的检出率37%(P<0.05)。DCG 对心肌缺血的检出率21.7%显著高于ECG 的检出率6.8%。且老年心脏病人心律失常、心肌缺血以无症状性及不典型性多见,故DCG 监测用于老年心脏病人更显优越。
Comparing and analyzing the results of 24-hour ambulatory electrocardiogram (DCG) and self-ECG in 350 senile patients with heart disease, the detection rate of arrhythmia by DCG was significantly higher than that of ECG by 82.3% (37%, P <0.05). DCG detection rate of myocardial ischemia 21.7% was significantly higher than the detection rate of ECG 6.8%. And elderly patients with cardiac arrhythmia, myocardial ischemia with asymptomatic and atypical more common, so DCG monitoring for elderly heart patients even more superior.
