The application of mathematics, natural sciences and engineering to medicine is gaining
momentum as the mutual benefits of this collaboration become increasingly obvious. This …

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 …

This study investigated the cardiac, vasomotor, and myocardial branches of the baroreflex in
fibromyalgia using the spontaneous sequence method. Systolic blood pressure (SBP) …

The objective of this study was to determine the response of heart rate and blood pressure
variability (respiratory sinus arrhythmia, baroreflex sensitivity) to orthostatic and mental …

Hysteresis of the baroreflex (BR) is the result of the different BR sensitivity (BRS) when
arterial pressure (AP) rises or falls. This phenomenon has been poorly studied and almost …

The relationship between heart rate and blood pressure, as well as cardiorespiratory
coupling, play a critical role in maintaining blood pressure and organ perfusion during …

Early detection of hemorrhage remains an open problem. In this regard, blood pressure has
been an ineffective measure of blood loss due to numerous compensatory mechanisms …

The arm of the baroreflex (BR) controlling peripheral resistances (PR), labeled as BR of PR
(prBR), was characterized through an extension of the cardiac BR (cBR) sequence analysis …

Baroreflex response consists of cardiac chronotropic (effect on heart rate), cardiac inotropic
(on contractility), venous (on venous return) and vascular (on vascular resistance) arms …

Congestive heart failure (CHF) is a cardiovascular disease associated with autonomic
dysfunction, where sympathovagal imbalance was reported in many studies using heart rate …
