Abstract

The invention relates to a low-power portable electrocardiograph monitoring system, and belongs to the field of portable human-body electrocardiograph monitoring. The low-power portable electrocardiograph monitoring system comprises an electrocardio-electrode, a lead wire, an electrocardiosignal conditioning circuit, a single chip control circuit, a low-power bluetooth circuit, a rechargeable lithium battery, a power supply management circuit, a smart phone and a server. According to the low-power portable electrocardiograph monitoring system, right-leg driving, active power filtering, double-instrument operational amplifier and digital smooth filtering are adopted, an electrocardiosignal is effectively extracted, an R-wave calculated heart rate is accurately detected by adopting a differential threshold method, a real-time electrocardiogram is drawn by utilizing the smart phone, electrocardiogram data can be transmitted to the server, and a doctor can examine and analyze the electrocardiogram data at the server. Low-power design is adopted, the size is small, and the low-power portable electrocardiograph monitoring system is suitable for crowds needing to pay attention to the self electrocardio situations whenever and wherever.

Description

technical field [0001] The invention relates to a low-power portable ECG monitoring system, which belongs to the field of portable human body ECG monitoring. Background technique [0002] With the changes in people's work, lifestyle, eating habits and population aging, the incidence of heart disease in my country is increasing year by year. The electrocardiogram can reflect the electrical activity process of the human heart, and has important reference value for the basic functions of the heart and its pathological research. It can analyze and identify various arrhythmias, and can also reflect the damage of the myocardium and the functional structure of the atria and ventricles. . Therefore, ECG monitoring is becoming more and more important. For people who already suffer from heart disease, they need to monitor their ECG anytime and anywhere and give feedback to the doctor in time. [0003] At present, the existing ECG equipment in the hospital is bulky, consumes a lot of...
