The most crucial step in diagnosing syncope is determining whether or not an arrhythmia is the cause. A new recording device, the continuous cardiac loop ECG recorder, affords prolonged ambulatory monitoring and can capture the rhythm at the time of syncope. To determine the impact of cardiac loop ECG recorders in diagnosing syncope, we reviewed the records of the first 48 patients referred for cardiac loop recording because of unexplained syncope or presyncope. Previous cardiac studies were nondiagnostic in all patients. In 36% of these patients, loop recording definitively determined whether an arrhythmia was the cause of symptoms. Median duration of monitoring was 28 days, with an average charge of $180 per month. Cardiac loop ECG recording is a convenient, safe, inexpensive, and potentially highly effective means of diagnosing unexplained syncope.
诊断晕厥最关键的一步是确定心律失常是否为病因。一种新型记录设备，即连续心脏环路心电图记录仪，可进行长时间动态监测，并能捕捉晕厥发生时的心律。为了确定心脏环路心电图记录仪在诊断晕厥中的作用，我们回顾了最初48例因不明原因晕厥或晕厥前状态而转诊进行心脏环路记录的患者的记录。之前所有患者的心脏检查均未明确诊断。在这些患者中，36%的患者通过环路记录明确确定心律失常是否为症状的病因。监测的中位持续时间为28天，每月平均费用为180美元。心脏环路心电图记录是诊断不明原因晕厥的一种方便、安全、廉价且可能非常有效的方法。
