BACKGROUND
Patient-activated continuous-loop event recorders (CER) are useful as a diagnostic tool in new episodes of palpitations and/or dizziness. So far, no analysis of optimal duration for monitoring in unselected patients has been published.
METHODS
During a period of 30 days, we prospectively evaluated the time until diagnosis using CER in patients with symptoms of palpitations and/or dizziness in general practice.
RESULTS
In total, 127 patients received an event recorder for a maximum duration of 30 days. Events were recorded by 104 patients (82%), of whom 83 (78%) showed an arrhythmia. After 2 weeks, 75% of all diagnoses and 83.3% of all clinically relevant diagnoses could be established.
CONCLUSION
The yield of event recording in general practice diminishes with recording time. A minimum recording time of 2 weeks seems necessary.
背景
患者激活式连续环事件记录仪（CER）作为心悸和/或头晕新发症状的诊断工具很有用。到目前为止，尚未发表关于对未选择患者进行监测的最佳时长分析。
方法
在30天的时间段内，我们前瞻性评估了在全科医疗中使用CER对有心悸和/或头晕症状患者进行诊断所需的时间。
结果
总共127例患者接受了事件记录仪，最长监测时长为30天。104例患者（82%）记录到了事件，其中83例（78%）出现心律失常。2周后，所有诊断中的75%以及所有临床相关诊断中的83.3%得以确立。
结论
在全科医疗中，事件记录的诊断率会随记录时间而降低。似乎有必要进行至少2周的记录。
