利用以往的运动负荷心电图诊断缺血性心脏病,是以出现症状或心动次数的最大值作为中止负荷的指标,因而,有不可忽视的危险因素。最近,日本九州大学医疗信息部的陶山晶子等人研究出以最小负荷诊断缺血性心脏病的新方法。他们从负荷心电图中求得ST冲动反应,并通过其阴性降低时间的长短来区别正常者与劳动型心绞痛。与以往的运动负荷试验相比,精确度高而且安全可靠。
The use of previous exercise-load ECG diagnosis of ischemic heart disease, the maximum number of symptoms or cardiac arrest as an indicator of the burden of suspension, therefore, there are risk factors that can not be ignored. Recently, Dosanji Yamazaki et al., Department of Medical Information, Kyushu University, Japan, developed a new method for diagnosing ischemic heart disease with minimum load. They obtained ST impulsive response from the load ECG and distinguished between normal and labor-type angina through the duration of their negative decrease. Compared with the previous exercise load test, high accuracy and safety.
