Prevalence and heart rate variability characteristics of premature ventricular contractions detected by 24-hour Holter among outpatients with palpitations in China: a cross-sectional study.

ABSTRACT:

Objective

To analyse the prevalence and heart rate variability (HRV) characteristics of premature ventricular contraction (PVC) detected by 24-hour Holter among Chinese outpatients with palpitations.

Design

A cross-sectional study.

Setting

This study was conducted in a tertiary hospital.

Participants

A total of 4754 outpatients who received 24-hour Holter for palpitations.

Main outcome measures

Prevalence, HRV time-domain and frequency-domain analyses of 24-hour Holter, and echocardiographic parameters were assessed. Propensity score matching (PSM) was applied to balance baseline variables (age, gender) to decrease the bias between comparison groups.

Results

The prevalence of PVC was 67.7% (3220/4754), and was higher in men than women (69.9% vs 66
