介绍基于微机的心电图和心电向量图检测分析仪，并给出了硬软件框图和技术特点。在临床实验的基础上，利用该仪器研究了常规12导联心电图和Frank导联心电向量图的转换关系，提出了一种全新的常规12导联心电图和Frank导联心电向量图联合检测的方法。 Introduce the computer-based ECG and ECG vector detection analyzer, and gives the hardware and software block diagram and technical features. On the basis of clinical experiments, this instrument was used to study the conversion between conventional 12-lead electrocardiogram and Frank’s lead electrocardiogram, and a new combined detection of 12-lead electrocardiogram and Frank’s lead electrocardiogram Methods.
