A method is described for detecting and counting ectopic beats using a small computer. The occurrence of an ectopic beat is identified by the relative duration of adjacent pulse intervals as demonstrated by simple arithmetical procedures. The method was validated by manual counting of records from 18 patients. 89% of 1474 ectopics were correctly identified. There were few false positive identifications 42. Although the method is unsuitable for the diagnosis of arrhythmias it is likely to be of value in epidemiological studies of such disturbances.
本文描述了一种使用小型计算机检测和计数异位搏动的方法。通过简单的算术程序所显示的相邻脉搏间期的相对持续时间来识别异位搏动的发生。该方法通过人工计数18例患者的记录进行了验证。在1474次异位搏动中，89%被正确识别。假阳性识别很少（42次）。虽然该方法不适用于心律失常的诊断，但在这类紊乱的流行病学研究中可能具有价值。
