Selecting Target Range with Accurate Vital Sign Using Spatial Phase Coherency of FMCW Radar
Applied Sciences, 2021 Respiration and heartbeat are basic indicators of the physiological state of human beings. Frequency-modulated continuous wave (FMCW) radar can sense micro-displacement in the human body surface without contact, and is used for vital-sign (respiration ...

Target Range Selection of FMCW Radar for Accurate Vital Information Extraction
IEEE Access, 2021 Frequency modulated continuous wave (FMCW) radar, which can detect the range and small displacement of a target, has been used for contactless vital information extraction.

The paradigm shift: Heartbeat initiation without “the pacemaker cell”
Frontiers in Physiology, 2022 The current dogma about the heartbeat origin is based on “the pacemaker cell,” a specialized cell residing in the sinoatrial node (SAN) that exhibits spontaneous diastolic depolarization triggering rhythmic action potentials (APs). Recent high-resolution

Implementation of the pulse rhythmic rate for the efficient diagnosing of the heartbeat
Healthcare Technology Letters, 2019 The mortality rate has risen due to the increase in number of cardiac patients in recent times due to the lack of unawareness of the symptoms. This work mainly aims to detect the anomalies of the rhythmic conditions of the pulse derived from the ...

Interoception and Premonitory Urges in Children and Adolescents With Tic Disorders
Clinical Psychology in Europe, 2023 [Background] Compared to healthy controls (HCs), adult Tic Disorder (TD) patients exhibit a lower interoceptive accuracy (IAcc) in heartbeat perception.

European Journal of Entomology, 2006 Using an opto-cardiograph combined with an infrared gas analyzer regular bouts of abdominal contractions were recorded from last instar larva of Bombus terrestris. The rate of CO2 release was about 0.7 ml g-1 h-1.

Vascular endothelial ageing, heartbeat after heartbeat [PDF]
Cardiovascular Research, 2009 The vascular endothelium starts to age at the first heartbeat. There is no longer a need to demonstrate that an increased resting heart rate--above 70 b.p.m.--is associated with the onset of cardiovascular events and reduces lifespan in humans. Each cardiac cycle imposes a mechanical constraint on the arteries, and we would like to propose that this ...

Frontiers in Physiology, 2023 The present view on heartbeat initiation is that a primary pacemaker cell or a group of cells in the sinoatrial node (SAN) center paces the rest of the SAN and the atria. However, recent high-resolution imaging studies show a more complex paradigm of SAN

Heartbeat and Somatosensory Perception [PDF]
NeuroImage, 2020 Abstract Our perception of the external world is influenced by internal bodily signals. For example, we recently showed that timing of stimulation along the cardiac cycle and spontaneous fluctuations of heartbeat-evoked potential (HEP) amplitudes influence somatosensory perception and the associated neural processing (Al et al., 2020 ...
