CPR中的心电节律识别

Rhythm analysis in CPR

由于胸外按压造成的干扰波会影响自动体外除颤仪对心搏骤停（CA）患者心电节律的判断,故判断心电节律时需要中断胸外按压.然而反复中断按压会影响心肺复苏（CPR）质量,进而影响CA患者的预后.为了提高CPR质量,减少胸外按压中断,准确电除颤,研究者们通过基于干扰混杂心电图数据、以及基于CA患者CPR过程中记录CA数据的不同滤波方法进行了心电节律识别研究.本文对CPR过程中心电节律的识别研究,包括干扰波的来源、干扰波的特征、节律识别的方法进行综述,为今后研究如何提高心电节律识别的准确率奠定基础.

It＇s necessary to interrupt cardiopulmonary resuscitation （CPR） for a reliable automatic external defibrillator （AED） rhythm analysis, because the mechanical activity from the chest compressions introduces artifacts in the electrocardiogram （ECG） that substantially lower the capacity of an AED to judge cardio-electric rhythm. However, repeated interruptions of compression will reduce the quality of CPR, which in turn affect the prognosis of patients with cardiac arrest （CA）. In order to improve the quality of CPR, reduce the interruptions of chest compression and implement accurate defibrillation, people have made many efforts on identifying ECG rhythm in CPR. The studies can be grouped into two broad categories： those based on the artificial mixture of ECG data and CPR artifacts and those based on CA data recorded during CPR. This article introduced researches for rhythm recognition in CPR, including sources and characteristics of CPR artifacts, methods of rhythm analysis, and provided a basis for the study of how to improve the accuracy of cardio-electric rhythm recognition.
