During the 1st year of operation of a national 24-hour ambulatory ECG-monitoring service, 531 recordings were collected. The information from these recordings and accompanying patient diaries were classified according to the indication for monitoring, the presence or absence of the 'indicated' sympton or other symptom in the diary and the presence or absence of correlating arrhythmias on the tape. On the basis of this categorization 7.5% of recordings were considered completely diagnostic (indicated symptom noted in diary with correlating arrhythmias). An additional 26.6% or recordings, although not completely diagnostic, were considered clinically useful in that they provided information regarding the relationship of symptoms to arrhythmias or the presence or absence of arrhythmias. Major causes of loss of information were poorly completed diaries or no diary, lack of precise definition of the indication for monitoring and technical faults resulting in uninterpretable recordings. Rectification of these deficiences could improve the efficiency of data collection and analysis.
在一项全国性的24小时动态心电图监测服务运营的第一年，共收集了531份记录。这些记录以及随附的患者日记中的信息，根据监测指征、日记中是否存在“指示”症状或其他症状以及磁带中是否存在相关心律失常进行了分类。基于这种分类，7.5%的记录被认为是完全诊断性的（日记中记录了指示症状且伴有相关心律失常）。另外26.6%的记录虽然不完全具有诊断性，但被认为在临床上是有用的，因为它们提供了有关症状与心律失常关系或心律失常存在与否的信息。信息丢失的主要原因是日记填写不完整或没有日记、监测指征定义不精确以及技术故障导致记录无法解读。纠正这些缺陷可以提高数据收集和分析的效率。
