一些研究结果表明,区域性左室壁运动异常是缺血的敏感和特异的标志。本文研究的目的是确定心动记波法(Cardiokymograph,CKG)能否检查出运动引起的室壁运动异常,估价它在临床冠心病诊断中,作为心电图运动试验的一种非侵入性辅助诊断方法的应用价值。一、方法: 1.心动记波器(CKG):包括两个部件:一个探头和一个信号调节装置。CKG探头用一个5厘米圆形扁平的电容板作为高频、低功率振荡器的部件。扁平电容板安放在塑料圈上,绑在胸部,有空气间隙将线圈与皮肤分隔开。通过直流电激动电容
Some studies have shown that regional abnormalities of left ventricular wall motion is a sensitive and specific marker of ischemia. The purpose of this study was to determine whether Cardiokymograph (CKG) can detect motion-induced wall motion abnormalities and to evaluate it as a noninvasive diagnostic aid for ECG exercise testing in clinical diagnosis of coronary heart disease Value. First, the method: 1. Heart beat recorder (CKG): includes two parts: a probe and a signal conditioning device. The CKG probe uses a 5-cm flat, flat capacitor plate as part of a high-frequency, low-power oscillator. Flat capacitive plate placed in the plastic ring, tied to the chest, the air gap will be separated from the skin and the coil. Capacitance is excited by DC
