The enhancement of parasympathetic control in newborn and mature guinea pigs, achieved through vagal stimulation and acetylcholine administration, was shown to increase the duration of spontaneously reversible fibrillation of the heart ventricles. Acetylcholine administration could prevent spontaneously irreversible fibrillation of the heart ventricles in old animals. The preservation of sympathetic control was shown to be important for the mechanisms of spontaneous restoration of normal cardiac rhythm.

Background: Calcium-mediated autonomic denervation has been shown to suppress postoperative atrial fibrillation (POAF) after coronary artery bypass grafting.
Objectives: This study sought to evaluate whether similar autonomic denervation can prevent POAF after mitral or aortic valve surgeries.
Methods: This research consisted of 2 single-center, randomized, double-blind, sham-controlled trials: CAP-AF2 (Calcium Autonomic Denervation Prevents Postoperative Atrial Fibrillation in Patients Undergoing Isolated Mitral Valve Surgery for Mitral Regurgitation) for mitral valve (MV) surgery and CAP-AF3 (Calcium Autonomic Denervation Prevents Postoperative Atrial Fibrillation in Patients Undergoing Isolated Aortic Valve Surgery) for aortic valve surgery.

Alexithymia is a psychological trait characterized by difficulty expressing emotions. Previous studies reported that individuals with higher alexithymia have a decreased sense of interoception, which is the sense of monitoring and controlling internal organs. Thus, we hypothesized that internal organ activity (cardiac activities in the present study) was easily affected by false feedback in individuals with severe alexithymia.

Purpose: Long-coronavirus disease (long-COVID) is associated with initial orthostatic hypotension and postural orthostatic tachycardia syndrome. Whether altered autonomic tone underlies these abnormalities is unknown. We compared autonomic function between patients with long-COVID and healthy controls, and within patients with long-COVID with different orthostatic hemodynamic phenotypes.

A literature review was conducted of epipharyngeal abrasive therapy (EAT) in the treatment of chronic epipharyngitis, focusing on the mechanism of action by autonomic nerve stimulation. The mechanism of action of EAT in stimulating the immune system has recently become clear. However, the mechanism of action of EAT on the autonomic nervous system remains to be elucidated.

Electrophysiological monitoring of pain provides objective measures that allow for pain control and adjustment of analgesia in non-communicative patients. Among the available electrophysiological devices, automated infrared pupillometry, Analgesia Nociception Index (ANI), and Nociception Level Index (NOL®) stand out. These non-invasive measurement systems analyze the sympathetic or parasympathetic nervous system response to painful stimuli by observing pupillary dilatation and reactivity (pupillometry), heart rate during respiration (ANI), or a combination of multiple parameters from the nociceptive-autonomic medullary circuit (NOL®).
