Entropy Measures in the Assessment of Heart Rate Variability in Patients with Cardiodepressive Vasovagal Syncope

Entropy, 2015
Sample entropy (SampEn) was reported to be useful in the assessment of the complexity of heart rate dynamics. Permutation entropy (PermEn) is a new measure based on the concept of order and was previously shown to be accurate for short, non-stationary ...

Vestibular Physiotherapy and Yoga in Vasovagal Syndrome: case report

Research, Society and Development, 2021
This study aimed to report the effects of vestibular physiotherapy (VP) associated with Yoga in a vasovagal syndrome (VVS) patient with dizziness and body imbalance complaints. We described a 22-year-old patient who underwent one year of VP with a frequency of one to two times per week (totaling 31 sessions).

Cardiovascular Autonomic Dysfunction Is the Most Common Cause of Syncope in Paced Patients

Frontiers in Cardiovascular Medicine, 2019
Introduction: Syncope and orthostatic intolerance in paced patients constitute a common clinical dilemma. We, thus, aimed to determine the etiology of syncope and/or symptoms of orthostatic intolerance in paced patients.Methods: Among 1,705 patients with
