Arterial pulse waves (PWs) such as blood pressure and photoplethysmogram (PPG) signals
contain a wealth of information on the cardiovascular (CV) system that can be exploited to …

Smart wearables provide an opportunity to monitor health in daily life and are emerging as
potential tools for detecting cardiovascular disease (CVD). Wearables such as fitness bands …

Light-to-digital converters (LDCs) are essential components in photoplethysmography (PPG)
readout chains. Over the past decade, PPG sensors have gathered increased interest due to …

Fiducial points of photoplethysmogram (PPG), first derivative PPG (VPG), and second
derivative PPG (APG) are essential in extracting numerous parameters to diagnose …

Photoplethysmography is a method to visualize the variation in blood volume within tissues
with light. The signal obtained has been used for the monitoring of patients, interpretation for …

Abstract Objective Pulse Rate Variability (PRV) has been widely used as a surrogate of
Heart Rate Variability (HRV). However, there are several technical aspects that may affect …

Background: Pulse transit time (PTT) is a key parameter in cuffless blood pressure
measurement based on photoplethysmography (PPG) signals. In wearable PPG sensors …

Education is integral to the American Academy of Sleep Medicine (AASM) mission. The
AASM Emerging Technology Committee identified an important and evolving piece of …

Objective. Photoplethysmography is a non-invasive optical technique that measures
changes in blood volume within tissues. It is commonly and being increasingly used for a …

Introduction: Aging is a physiological process characterized by progressive changes in all
organ systems. In the last few decades, the elderly population has been growing, so the …
