Similarly, persistent recording of an electrocardiogram (ECG) or photoplethysmogram (PPG) by a wearable sensor could provide a sensible perspective of the heart state of a patient throughout the day to record conditions as hypertension, anxiety, uneasiness, diabetes, etc.
PixArt's Heart Rate Monitor sensor deploys the photoplethysmogram (PPG) technique, which transmits LED light waves into the skin of the user and measures the response change caused by absorption due to pulsating arterial blood.
The ministry is exploring rehabilitation via Human Computer Interface using Electroencephalogram, Photoplethysmogram for cardiovascular regulation and arterial stiffness, Electroocculograms, Blowswitches and Impedance Plethysmogrames etc.
Additionally, we will develop an algorithm for the detection of pulse wave alternans in the photoplethysmogram recorded from the finger, and develop a mobile application to detect repolarization alternans from a fingertip pulse wave using the built-in camera lens.
Elif Derya Ubeyli, et al presented eigenvector methods for analysis of the photoplethysmogram (PPG), electrocardiogram (ECG), electroencephalogram (EEG) signals recorded in order to examine the effects of pulsed electromagnetic field (PEMF) at extremely low frequency (ELF) upon the human electrophysiological signal behaviour.
