近年来,欧美各国无创伤性检查方法有了发展,心壁波动图(Cardiokymography)简称心波图(CKG)就是其中一种新型、重要的检查方法。如今,在冠心病的诊断中,心电图功量负荷试验(Ergometer ECG)是一个主要检查方法。但是这种检查受很多因素影响;如病人的状况(年龄、性别、症状等)、药物、负荷量、所选择的心电图导联数目等,甚至在安静状态下异常的心电图(如左束枝阻滞、WPW综合征等)也使得负荷状态下缺血性心电图的分析变为困难。有人认为这种心电图功量负荷试验在冠心病发病率较低的人群中,也往往会出现很高的假阳性率。现已表明,心波图可以弥补心电图功量负荷试验的上述不足。在检 In recent years, non-invasive examination methods in Europe and the United States have been developed. Cardiokymography referred to as CKG is one of the new and important methods of examination. Today, Ergometer ECG is a major test for the diagnosis of coronary heart disease. However, this test is affected by many factors such as the patient’s condition (age, sex, symptoms, etc.), the amount of medication, the amount of load, the number of ECG leads selected, and even abnormal ECGs in a quiescent state Hysteresis, WPW syndrome, etc.) also makes it difficult to analyze ischemic electrocardiograms under load. Some people think that this ECG load test in people with a lower incidence of coronary heart disease, but also often have a high false positive rate. It has been shown that the heartbeat graph can make up for the deficiencies of ECG load test. Checked
