Description

Portable ECG Measurement System

technical field

The utility model is a portable electrocardiogram measurement system, especially a hand-held detector made of metal, which replaces the traditional patch sensor to obtain weak and noisy electrocardiogram signals. After the signal is amplified and filtered, a clear and usable ECG signal is obtained. In addition, in order to perform the abnormal heart rhythm judgment function, the portable electrocardiogram measurement system is directly collected to the computer or smart phone, connected to the computer cloud to process a large amount of file data, and used as the data database basis of the abnormal heart rhythm judgment program. the

Background technique

Heart disease ranks second in the top ten causes of death among Chinese people, and the high ranking seriously threatens the health of Chinese people. However, the current method of measuring ECG is still not convenient enough. The human body’s ECG signal is very weak. To extract the signal from the hand, the conduction path from the heart to the hand must be considered, as well as the influence of external environmental interference. In addition, each person's physiological condition is different. To quickly and accurately test the ECG signal by hand, it is necessary to do an experiment on the influence of the external environment on the hand-tested ECG signal; and then construct an equivalent correction circuit for the external environment and the human body test to eliminate the source of interference. Developed a high-accuracy portable electrocardiogram machine due to the influence of hand-measuring ECG signals. the

Existing electrocardiographs mainly adopt the traditional twelve-lead measurement method of electrode pads, which is accurate but not convenient enough. the

According to the existing electrocardiograph, there is also a large volume, which is difficult to carry and measure at any time and the cost is too high. In addition, to measure the patch, it is necessary to remove the clothes and stick it on the chest of the user, which reduces the comfort of the user. the

Therefore, the existing electrocardiograph, which is time-consuming and inconvenient to carry, still has the aforementioned problems to be improved. the

In view of this, the utility model is a digital system for measuring the electrocardiogram from both hands. The originally time-consuming and inconvenient electrocardiogram machine is transformed into a light-weight and easy-to-carry electrocardiogram machine that is convenient for measurement. It can observe the heart condition at any time and can be widely used in Out-of-hospital first aid and prevention and treatment of cardiovascular diseases. the
