| 中文摘要: |
| 本文首先给出空间心电向量环在额面投影的函数,用电学原理,得出标准导联的心电波形电压的数学解析式。然后,根据心电波形数学式,得出平均心电轴的估算公式。这对应用微机分析心电图和估算平均心电轴,可能有一定的裨益。 |
| 英文摘要: |
| The projected functions of the spatial cardiac electrical vector loops on the frontal plane of the body are given in this paper. The cardiac electrical wave functions are obtained by electricity calculations. Furthermore the formulas for calculating mean electrical axis are followed from the cardiac electrical wave functions. This may be useful to apply microcalculator for analysis of ECG and to find mean electrical axis. |
