本文报导应用心电体表峰值标测图(EPM)诊断潜、慢克31例的经验。用84导体表电极提取心电的各峰、谷值经计算机加工后获得负的和正的电位面积图(Q、R、S…+T 和-T图)。经与正常对照(100例)相比,克山病中17/31例出现异常 Q 图,然而常规心电图波形基本正常。以上小 Q 图可反映克山病的小灶坏死。此外,患者普遍有 T 图的低电压带异常显著增宽。本法可助在流行区作为早期诊断和病情监测之用。
This article reports the application of ECG peak surface mapping (EPM) diagnosis of potential, slow grams of experience in 31 cases. The peaks of the electrocardiogram were extracted from the electrodes of the 84 conductor sheet and the valleys were processed by computer to obtain the negative and positive potential areas (Q, R, S ... + T and -T). Compared with the normal control (100 cases), Keshan disease in 17/31 cases showed abnormal Q-plot, however, the normal ECG waveform was normal. The above small Q map can reflect Keshan disease of small lesions necrosis. In addition, the general low T-band abnormalities in patients with abnormal widened significantly. This law can be used in endemic areas for early diagnosis and disease monitoring purposes.
