Impact of Premature Ventricular Complexes on Respiratory and Physical Health

Official title: Investigation of Respiratory Functions, Muscle Strength, Physical Activity Level, and Quality of Life in Individuals With Premature Ventricular Complexes

Run by Izmir Democracy University · NCT07396597 · Data updated 2026-11-12

This study tests how premature ventricular complexes affect breathing, respiratory and hand strength, cough, physical activity, and quality of life in adults with PVCs compared with healthy controls.

Is this trial a fit for you?

Likely a good fit

Adults aged 18-80 with symptomatic PVCs (PVC burden ≥10% and resistance to at least one antiarrhythmic medication) who can complete all assessments.

Probably not a fit

Individuals with reduced left ventricular ejection fraction (<45%) unless PVC-induced cardiomyopathy is demonstrated, or those unable to participate in all assessments, may not benefit.

What this trial studies

This observational study compares adults with symptomatic premature ventricular complexes to healthy controls to explore respiratory function, respiratory muscle strength, cough strength, handgrip strength, physical activity, and quality of life. Participants will undergo clinical assessments, questionnaires, and measurements to characterize these parameters. The study also aims to identify differences between PVC patients and controls and contribute new data to the field.

Why it matters

Potential benefit: If successful, findings could clarify how PVCs relate to respiratory and physical function and guide future management to improve patient well-being.

How similar studies have gone: Previous research has shown associations between PVCs and various functional parameters, but direct comparisons with healthy controls in this combination are limited, making this study relatively novel.
