Motion Artifact Reduction in Impedance Plethysmography Signal
… studies addressing the problem of removing motion artifact from the electrocardiogram (ECG) and photoplethysmography (PPG) signals in the past few years. However, no such study exists for the Impedance Plethysmography (IP) signal. The IP signal can be used to monitor respiration in mobile …

Motion artifact reduction of electrocardiograms using multiple motion sensors
… ECG signal, the most problematic being that of motion artifacts. As an individual wearing a surface ECG moves, their movements will add noise to the signal. This noise is particularly difficult to remove, as it will change depending on the movements of the user and will often fall in the same …

Motion artifact reduction for wearable photoplethysmogram sensors using micro accelerometers and laguerre series adaptive filters
… becomes highly corrupted when the wearer is in motion, rendering the measured signal useless. This thesis develops an adaptive motion artifact reduction scheme to recover the underlying physiologic information from the corrupted signal using a collocated accelerometer as a motion reference and …

Cardiac Fibrosis and Ventricular Arrhythmogenesis: Unravelling the influence of fibrosis on electrical dysfunction in the development of heart failure
… scales, the SHR volumes displayed a marked reduction in fiber rotation in the sub epicardium. In addition, significant tissue connectivity reduction associated with fibrosis was also observed. Finally, electrical activation simulations demonstrated slowing in conduction velocity (CV) in the …
