“…To estimate blood pressure using features taken from electrocardiogram and photoplethysmogram signals, a non-invasive method was created [24,25]. Through machine learning specifically, artificial neural networks, their non-invasive method was meant to estimate blood pressures [26,27,28]. Initially, they conducted their experiment on a real data set of more than 2,000 electrocardiogram, blood pressures, and photoplethysmogram signals from patients of various hospitals within the years 2001 up to 2008.…”
