Long-term characterization of arterial blood pressure series

A simply method to study how arterial blood pressure values rise and fall during the till test, which is the tool universally used to evaluate people with faint episodes. Not only what is happening but how, that is calculating the angle and longitude of the arterial blood pressures ramps. This is accomplished from smoothed versions of the series of systolic pressure, which is approximated by line segments fitted to it. Then, the extracted features are used to make comparisons between the three groups; one group was formed with the controls. The other two groups include people with a history of syncope, which are classified as positive or negative depending on the results of tilt testing.
