Characterization of sympathicotonia in post‐covid condition (long covid) and healthy controls using long‐term electrodermal activity (EDA) follow‐up

Clinical Physiology and Functional Imaging, Volume 45, Issue 6, November 2025.
Abstract Purpose After SARS‐CoV‐2 infection, some patients develop post‐COVID condition (PCC), often associated with sympathicotonia. This study aimed to characterize sympathicotonia in PCC patients using a novel long‐term electrodermal activity (EDA) analysis via a smart ring and evaluate its clinical applicability. Methods Seventeen PCC patients were

Etiological diagnosis, prognostic significance and role of electrophysiological study in patients with Brugada ECG and syncope. [PDF]

, 2017
BACKGROUND: Syncope is considered a risk factor for life-threatening arrhythmias in Brugada patients. Distinguishing a benign syncope from one due to ventricular arrhythmias is often difficult, unless an ECG is recorded during the episode.
