Mechanism of syncope: role of ambulatory blood pressure monitoring and cardiovascular autonomic function assessment.

ABSTRACT:

Background and aims

Identifying the haemodynamic mechanism of autonomic syncope is the essential pre-requisite for effective and personalized therapy aimed at preventing recurrences. The present study assessed the diagnostic efficacy of a two-step assessment.

Methods

Multicentre prospective, cross-sectional, observational study. Patients affected by severe autonomic syncope underwent a two-step assessment including 24-h ambulatory blood pressure monitoring and short cardiovascular autonomic function assessment (SCAFA). SCAFA consisted of carotid sinus massage (CSM), performed in patients ≥40 years old, a passive standing test, and a 'fast' head-up tilt test scheduled sequentially during one session on a tilt table.

Results

The study population consisted of 333 patient
