Abstract
Systems, methods, apparatuses, and computer program for reconstructing electrocardiogram (ECG) waveforms from photoplethysmogram (PPG). A method for cardiovascular monitoring and analytics may include obtaining an electrical signal of a heart. The method may also include obtaining a circulatory signal related to a pulsatile volume of blood in tissue. The method may also include preprocessing the electrical signal and the circulatory signal. The method may further include training a mapping using the preprocessed electrical signal and circulatory signal. In addition, the method may include deriving cardiovascular data based on the trained mapping of the preprocessed electrical signal or circulatory signal.
