Abstract: With the rapid development of electrocardiography and computer network, as well as the improvement of electrocardiac signal processing techniques in biomedical engineering, the most advanced state-of-the-art three-dimensional electrocardiograph in China, featuring functions such as the automatic diagnosis system of color vector cardiogram, heartbeat encoding, multiple heartbeat superimposition, automatic diagnosis and localization of ventricular ectopic beats, pacemaker pulse detection and marking technology, etc, compensates for the inability of conventional electrocardiograms to provide definite diagnoses for certain arrhythmias, atypical myocardial infarction, myocardial infarction combined with conduction disorders, and other diseases. This not only broadens the clinical application scope of vector cardiogram but also imposes higher demands on the standardization of diagnostic criteria for vector cardiogram in clinical practice. This consensus document aimed to promote the standardization of the diagnostic criteria of vector cardiogram, better facilitate the management of vector cardiogram reports, and lay a solid foundation for the future development of artificial intelligence interpretation of vector cardiogram in China.
