Electrocardiogram is the simplest, fastest, and most economical clinical examination method for various cardiovascular diseases, including arrhythmia, ventricular and atrial hypertrophy, myocardial ischemic injury, myocardial infarction, etc. It is the cornerstone of cardiovascular disease testing. Due to the complexity and variability of electrocardiogram signals, traditional electrocardiogram analysis techniques have certain limitations and cannot truly achieve automatic, fast, and accurate analysis. They must rely on professional doctors for analysis and interpretation. However, most medical institutions, especially primary hospitals, have a shortage of professional electrocardiogram physicians, which limits the application effect of electrocardiogram examination for diseases and affects the timely and accurate diagnosis, prevention, and treatment of cardiovascular disease patients at the grassroots level.
