The system simultaneously analyzes the cardiac function state from fourelectrical safety isolation between the human body and a computer and transmits input signals to the computer processing system. The system simultaneously analyzes the cardiac function state from fouraspects of cardiac force, cardiac rhythm, cardiac rate and blood pressure, can realize the myocardial ischemia detection, the pulseless electrical activity detection, the cardiac reserve detection of aspects of cardiac force, cardiac rhythm, cardiac rate and blood pressure, can realize the myocardial ischemia detection, the pulseless electrical activity detection, the cardiac reserve detection of ar

Description

A heart function detection system based on heart sound and electrocardiogram technical field The invention relates to a human heart function detection system and method, in particular to a heart sound and electrocardiogram-based heart function detection system and method, belonging to the technical field of medical electronic instruments. Background technique Heart sound signal is one of the most important acoustic signals in the human body. Changes in heart sound and appearance of murmurs are often the earliest signs of organic heart disease. When cardiovascular disease has not yet developed enough to produce other symptoms and signs (such as patient pain, abnormal ECG etc.), effective early diagnostic information can be obtained from heart sounds. And the main problem in most heart failure patients is the reduction of myocardial contractility. Electrocardiography is the best way to monitor cardiac chronotropy and variable conductance, but it cannot be used to monitor ca...
