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.

Wavelet Analysis of Blood Pressure Waves in Vasovagal Syncope [PDF]
, 1999 We describe the multiresolution wavelet analysis of blood pressure waves in vasovagal syncope affected patients compared with healthy people one. We argue that there exist subtle discriminating criteria which allow us to isolate particular features ...

Arrhythmia & Electrophysiology Review, 2018 Vasovagal syncope (VVS) is due to a common autonomic reflex involving the cardiovascular system. It is associated with bradycardia (cardioinhibitory response) and/or hypotension (vasodepressor response), likely mediated by parasympathetic activation and sympathetic inhibition. While generally a situational, isolated and/or self-limited event, for some,
