Heart rate variability in BPPV

Evaluation of Autonomic Function Using Short-Term Heart Rate Variability in Patients With Benign Paroxysmal Positional Vertigo: A Prospective Case-Control Study

Observational Istanbul Aydın University · NCT07472998

This project will test whether short-term heart rate variability measurements differ between adults with BPPV and age- and sex-matched healthy controls.

What this trial studies

This prospective case-control study compares short-term heart rate variability (HRV) between adults with clinically confirmed benign paroxysmal positional vertigo (BPPV) and matched healthy controls. Recordings will focus on parasympathetic indicators such as RMSSD and the coefficient of variation of RR intervals (COV RR/R). People with known cardiac disease, arrhythmias, or on medications that affect HRV are excluded to reduce confounding. The approach aims to clarify whether altered vagal activity accompanies BPPV onset or recurrence.

Who should consider this trial

Good fit: Ideal candidates are adults (18+) with BPPV confirmed by Dix-Hallpike or Roll testing, no known cardiac disease, and able to give informed consent, plus age- and sex-matched healthy adults without vestibular disorders as controls.

Not a fit: People under 18, those with cardiac disease or arrhythmias, or anyone taking medications that directly affect HRV are unlikely to benefit or be eligible.

Why it matters

Potential benefit: If successful, the findings could provide an objective autonomic marker linked to BPPV that may inform prevention or personalized management strategies.

How similar studies have performed: Some preliminary work links stress and autonomic changes to vestibular symptoms, but objective HRV data specifically in BPPV is limited and relatively novel.
