Color vector cardiogram display method

The invention discloses a color vector cardiogram display method which comprises the following steps: S1, acquiring orthogonal lead electrocardiogram data, and recording each of x, y and z lead voltage amplitudes of bioelectricity of a heart of a human body; S2, forming an observation face, i.e. combining the orthogonal lead electrocardiogram data in pairs to form the observation face; S3, on the observation face, expressing each instantaneous voltage component of the orthogonal lead electrocardiogram data with a lacrimal point, and sequentially marking each lacrimal point to form vector cardiographic loops of the observation face; S4, marking out a P vector cardiographic loop, a QRS vector cardiographic loop and a T vector cardiographic loop for the orthogonal lead electrocardiogram data according to an activity sequence of the bioelectricity of the heart; S5, dividing the QRS vector cardiographic loop formed in the step S4 into three sections of different vectors, wherein the three sections of different vec
