While autonomic dysregulation and repolarization abnormalities are observed in subarachnoid hemorrhage (SAH), their relationship remains unclear. We aimed to measure skin sympathetic nerve activity (SKNA), a novel method to estimate stellate ganglion nerve activity, and investigate its association with electrocardiogram (ECG) alterations after SAH. We recorded a total of 179 SKNA data from SAH patients at three distinct phases and compared them with 20 data from controls.

Research on interoception has revealed the role of heartbeats in shaping our perceptual awareness and embodying a first-person perspective. These heartbeat dynamics exhibit distinct responses to various types of touch. We advanced that those dynamics are directly associated to the brain activity that allows self-other distinction.

Pathophysiological Significance of α-Synuclein in Sympathetic Nerves: In Vivo Observations.

Neurology

February 2025

From the Autonomic Medicine Section, Clinical Neurosciences Program, Division of Intramural Research, National Institute of Neurological Disorders and Stroke, NIH, Bethesda, MD.

Background And Objectives: Lewy body diseases (LBDs) such as Parkinson disease (PD) feature increased deposition of α-synuclein (α-syn) in cutaneous sympathetic noradrenergic nerves. The pathophysiologic significance of sympathetic intraneuronal α-syn is unclear. We reviewed data about immunoreactive α-syn, tyrosine hydroxylase (TH, a marker of catecholaminergic fibers), and the sympathetic neurotransmitter norepinephrine (NE) in skin biopsies from control participants and patients with PD, the related LBD pure autonomic failure (PAF), the non-LBD synucleinopathy multiple system atrophy (MSA), or neurologic postacute sequelae of severe acute respiratory syndrome coronavirus 2 (neuro-PASC).

Left superior cervical ganglia lymph node mimicry and its role in rat ventricular arrhythmias following myocardial infarction.

Acta Physiol (Oxf)

February 2025

Department of Cardiology, Cheeloo College of Medicine, Shandong Provincial Qianfoshan Hospital, Shandong University, Jinan, China.

Aim: Sympathetic overactivation may lead to severe ventricular arrhythmias (VAs) post-myocardial infarction (MI). The superior cervical ganglion (SCG) is an extracardiac sympathetic ganglion which regulates cardiac autonomic tone. We aimed to investigate the characteristics and functional significance of SCG on neuro-cardiac communication post-MI.

Subclavian Ansae Stimulation on Cardiac Hemodynamics and Electrophysiology in Atrial Fibrillation: A Target for Sympathetic Neuromodulation.

JACC Clin Electrophysiol

December 2024

St Bartholomew's Hospital, Barts Health NHS Trust, London, United Kingdom; William Harvey Research Institute, Queen Mary University of London, London, United Kingdom. Electronic address:

Background: The sympathetic autonomic nervous system plays a major role in arrhythmia development and maintenance. Historical preclinical studies describe preferential increases in cardiac sympathetic tone upon selective stimulation of the subclavian ansae (SA), a nerve cord encircling the subclavian artery.

Objectives: This study sought to define, for the first time, the functional anatomy and physiology of the SA in humans using a percutaneous approach.
