Electrocardiograph and photoplethysmograph superimposition as an investigative tool for circulatory function
Maguire, Michael and Markham, Charles and Ward, Tomas (2001) Electrocardiograph and photoplethysmograph superimposition as an investigative tool for circulatory function. In: IEE Irish Signals and Systems Conference, 2001, NUI Maynooth.
This paper set out to examine the usefulness of the electrocardiograph (ECG) and photoplethysmograph (PPG) superimposition as an investigative tool for circulatory function. Further, a system was constructed and an experimental protocol established to examine this proposition. The three main components of circulatory function are pulse rate, arterial compliance and blood pressure. These components are each interrelated, and these relationships are the subject of much research. It was decided, focusing on blood pressure, to examine the superimposition information with regard to systolic, diastolic and mean blood pressure. Data was collected, conclusions were drawn and interesting possibilities for further work emerged.
