Heart rate variability (HRV) is a valuable noninvasive tool of assessing the state of
cardiovascular autonomic function. The interest in heart rate monitoring without electrodes …

Background: The heart rate variability (HRV) analysis is a well-known method demonstrating
its value over the years in different medical fields. However, it still has its known limitations …

Background Reduced heart rate variability (HRV), a non-invasive marker of autonomic
dysfunction, and an unhealthy lifestyle are associated with an increased morbidity and …

Akselrod et al 1 were the first to report that the analysis of spontaneousfluctuations in RR
interval could provide direct insight into the physiology of the autonomic control branches …

Background: Assessment of heart rate variability (HRV) is an effective non-invasive tool to
obtain data on cardiac autonomic modulation and may be assessed by a range of devices …

Heart rate variability (HRV) is a non-invasive tool to assess the cardiac autonomic integrity
and cardiovascular homeostasis (Electrophysiology, 1996). HRV quantifies the …

The heart is a key component of the human body, acting as a pump that transfers
oxygenated and deoxygenated blood around the body. Like all other organs, it is …

Despite its extensive use in physiological and clinical research, the analysis of HRV (heart
rate variability) is still poorly supported by rigorous reliability studies. The main aim of the …

Objectives: This study sought to determine whether Holter-based parameters of heart rate
variability (HRV) are independently associated with incident heart failure among older adults …

Heart rate variability (HRV) has become a popular method for the studies of physiologic
mechanisms responsible for the control of heart rate fluctuations, in which the autonomic …
