24小时长程心电图1000例分析

Value of 24-Hour Ambulatory Electrocardiogram Monitoring in Detecting Arrhythmias in 1000 Cases

分析1000例长程心电图,检出心律失常共1624例次,其中室速44例(4.4％),在相同时间内,检查住院患者的常规心电图共18198例,检出室速仅17例(0.093％)。对原因不明的昏倒或晕厥患者,大多能获得明确答案。分析结果表明,该项检查明显优于常规心电图。文中提出了须与变异“伪象”相鉴别。探讨其发生原因有:①电极位置的影响;②体位变动的影响。并建议监测导联改用CM_6较好。

24-hour Holter Monitoring in 1000 cases detected arrhythmias 1 624 cases/times. Among them ventricular tachycardias (V.T.) were recorded in 44 patients (4.4%), whereas, in the same period, the detection rate of V.T. in 18 198 routine ECGs was only 17 cases (0.093%). Thus, the unknown causes of syncope or dizziness among most patients were clarified. The results thus obtained indicate that ambulatory ECG is superior to routine ECG. But precaution should be taken to exclude artefacts. The relevant factors contributing to occurrence of such artefacts may be : 1 ) Location of electrode, 2 ) Changing body position. In order to avoid the artefacts, we suggest that CM6 be selected as location for exploring electrode.
