Deriving the Standard 12-lead ECGbased on Weighed Epicardial Potential

It is very important to redure the body surface electrodes as much as possible in recording ECG clinically. By constructing human heart profile model, based on the characteristic of electrocardic physiology, the authors put forward a new method of weighed epicardial potential to study the relationship between body surface potential and epicardial potential. Thus, the unknown body surface potential could be derived by the selected body surface potential. This method has been proved practical in diagnosing and locating myocardial ischemia and myocardial infarction with stardard 12-lead ECG.

脑电放大器体表电位测量设计与实现

提出了一种采用脑电放大器实现BSPM的方案。方案采用两台64导联脑电放大器采集体表电位信号,通过零相位数字滤波器滤除干扰,最后结合导联布置位置和处理后的信号重构出BSPM。实验结果表明,提出的方案能够有效获取到与心脏电活动对应的BSPM。提出的方法在复杂心脏疾病诊断上具有巨大的潜力。
