高频心电图国内外已有报告,但是由于使用仪器的非统一标准,影响了互相交流和诊断方法的一致性,我们自制干电池高频心电示波器,此专用机性能稳定,灵敏度高。我们检查了60例健康人、冠心病13例、心肌病2例、高血压病2例,现摘要报告如下: 目前高频心电图仪性能标准不统一,灵敏度不高,各项技术指标不一致,增益从30-100mm/mV,扫描速度分别选用200、300、525mm/s不等,频率响应选用500-3000周/s,影响 High-frequency electrocardiogram has been reported both at home and abroad. However, due to the non-uniform standard of using instruments, which affects the mutual communication and the consistency of diagnostic methods, we manufacture self-made dry-cell high-frequency ECG oscilloscopes with stable performance and high sensitivity. We examined 60 healthy people, 13 cases of coronary heart disease, 2 cases of cardiomyopathy, hypertension in 2 cases, the summary report is as follows: At present, high-frequency electrocardiograph performance standards are not uniform, the sensitivity is not high, the technical indicators are inconsistent, the gain From 30-100mm / mV, scanning speed were selected 200,300,525 mm / s, the frequency response of 500-3000 weeks / s, the impact
