Prevention of cardiovascular disease (CVD) remains one of the largest public health
challenges of our time. Identifying individuals at increased cardiovascular risk at an …

Photoplethysmography is a key sensing technology which is used in wearable devices such
as smartwatches and fitness trackers. Currently, photoplethysmography sensors are used 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 …

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 …

Vascular aging (VA) involves structural and functional changes in blood vessels that
contribute to cardiovascular disease. Several noninvasive pulse wave (PW) indices have …

Aims Although mobile health tools using photoplethysmography (PPG) technology have
been validated for the detection of atrial fibrillation (AF), their utility for heart rate assessment …

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 …

Abstract Study Objectives Photoplethysmography (PPG) in consumer sleep trackers is now
widely available and used to assess heart rate variability (HRV) for sleep staging. However …

Background During general anesthesia, the surgical pleth index (SPI) monitors nociception.
The evidence of SPI in the elderly remains scarce. We aimed to investigate whether there is …
