Prevent Cardiovascular Disease to Detection Health Status by Design and Measurement of an Electrocardiogram Circuit

Abstract

Cardiovascular disease, especially myocardial infarction, is a disease that has gained increasing concern in today's more health-conscious society. Usually, these disorders cause abnormal heart beats. The collection or monitoring of heartbeat behavior is good way to judge people's current heart‘s health status. For getting this kind signal, the application of ECG is extremely important. The manufacture of ECG relies on electronic engineering. The electrical signal produced by the heart is very small. Acquiring tiny signals is always difficult. The reason of difficult is that there is error in the actual collection, and when the input signal is small, the error is relatively large. So the function that the ECG needs to have is to be able to accurately measure and optimize the signal, and in the final obtain a clear and obvious electrocardiogram by optimizing the collected signals. The principle of used on making an ECG is to complete a circuit that can correctly process the input signal. This includes using amplifiers and filters to transfer the signal to the output signal as a waveform. Based on such a combination of the circuit and some components, a fully functional ECG is successfully fabricated. By recording and analyzing the collected ECG, it is possible to discover and treat these kinds of diseases in the human body.
