The Relationship Between Heart Rate Recovery and Heart Rate Variability in Coronary Artery Disease

open access: yesAnnals of Noninvasive Electrocardiology, 2006
Background: Reduced heart rate recovery (HRR) in coronary artery disease (CAD) is predictive of increased cardiovascular mortality and is related to reduced parasympathetic tonus. Objective: To investigate HRR and heart rate variability (HRV) measured at

PPGnet: Deep Network for Device Independent Heart Rate Estimation from Photoplethysmogram [PDF]

open access: yesarXiv, 2019
Photoplethysmogram (PPG) is increasingly used to provide monitoring of the cardiovascular system under ambulatory conditions. Wearable devices like smartwatches use PPG to allow long term unobtrusive monitoring of heart rate in free living conditions. PPG based heart rate measurement is unfortunately highly susceptible to motion artifacts, particularly

Heart rate variability while assessing transplanted heart reinnervation

open access: yesИнновационная медицина Кубани, 2019
Key difference of the transplanted heart is its full surgical denervation which causes features of transplanted heart physiology. Eventually a great number of studies appeared and they showed signs of innervation partial restoration and its influence on ...

Predicting Heart Failure with Attention Learning Techniques Utilizing Cardiovascular Data [PDF]

open access: yesarXiv
Cardiovascular diseases (CVDs) encompass a group of disorders affecting the heart and blood vessels, including conditions such as coronary artery disease, heart failure, stroke, and hypertension. In cardiovascular diseases, heart failure is one of the main causes of death and also long-term suffering in patients worldwide. Prediction is one of the risk
