本文根据球面心电场波阵面传递假说及对称座标法,提出新的心脏-体表定位方案和H-C导联心电扫查标测法。在31例用ECG及VCG诊断的陈旧性心肌梗塞病例中,以H-C导联与各习用导联作同步标测比较。H-C导联扫查标测的结果表明:除间壁、左前壁和左侧壁梗塞与Wilson导联标测一致外,其右界十分清晰,还能较满意地定出上壁、膈面和右室梗塞的体表投影,其中假性梗塞者占12.9％(与临床表现吻合),梗塞累及右室者占35.5％,累及膈面者占41.9％,累及上壁者占45.2％。在本文27/31例梗塞中,有22种不同的体表投影情况。
In this paper, based on the spherical electric field wavefront transfer hypothesis and symmetry coordinate method, a new heart-surface positioning scheme and H-C lead ECG scanning method are proposed. In 31 cases of old myocardial infarction diagnosed by ECG and VCG, the H-C lead was compared with the conventional lead for synchronous mapping. HC lead scan mapping results show that: in addition to the wall, left anterior wall and left wall infarction and Wilson lead mapping consistent, the right boundary is very clear, but also more satisfactory to determine the upper wall, diaphragmatic surface and Right ventricular infarction of the body surface projection, which accounted for 12.9% of the pseudo-infarction (consistent with clinical manifestations), infarction involving the right ventricle accounted for 35.5%, involving the diaphragm surface accounted for 41.9%, involving the upper wall accounted for 45.2%. In this 27/31 infarct scenario, there are 22 different surface projections.
