引言采用Holter监测器记录可走动病人的心电图在过去几年中已成为常规的诊断技术。这些记录是在12到24小时期间进行的,然后由冠心病护理护士用快速回放装置进行处理。该护士试图扫视这些记录,去掉所有正常的数据,识别出先兆的心律失常,他然后将识别出的心律失常的心电图记录纸送给要作出诊断的心脏科专家。这一过程在进行记录之后可能还要花去好几天时间。护士的工作是繁重费时的,而且常常出现人为的差错。近来已研制出计算机系统以自动分析Holter磁带,但是在记录和
Introduction Holter monitors recording ambulatory patients have become routine diagnostic techniques in the past few years. These records were taken between 12 and 24 hours and were then processed by the coronary care nurse using a quick-return device. The nurse attempted to scan the records, remove all normal data and identify the precursor arrhythmia. He then sent the cardiograph paper of the identified arrhythmia to the cardiologist who was to be diagnosed. It may take several days for this process to be recorded. Nurses work is lengthy and time-consuming, and often human error occurs. Computer systems have recently been developed to automate the analysis of Holter tapes, but in recording and
