The purpose of this article is to discuss possible ways of improving the quality of ECG signals in order to obtain more reliable results. Contractions of the heart muscle are caused by electrical impulses, which, when recorded on a graph, form an electrocardiogram. Why does the quality of the ECG signal matter?

According to 2 recent articles (2, 3), the computer misses one third of STEMI, but misses many more subtle MI that do not meet STEMI criteria. This one was not even so subtle!!!
