Key result
Ventricular extrasystoles (≥5000/24h) were associated with significantly reduced right ventricle four-chamber strain (19.37 vs 22.34, p<0.001) compared to healthy controls.
Why the study?
While the adverse effects of ventricular extrasystoles on the heart have been demonstrated, their effects on the right ventricle using strain imaging remained to be investigated.
Does a high burden of ventricular extrasystoles (≥5000/24h) impair right ventricular function measured by strain imaging in adult patients?

Frequent ventricular extrasystoles (≥5000/24h) are associated with significant impairment in right ventricular function as measured by strain echocardiography, highlighting the need for RV monitoring in these patients.
Frequent VES may impair RV strain; leaves open whether imaging alters management in high-burden patients.
AIM: The adverse effects of ventricular extrasystoles (VES) on the heart, such as induced dyssynchrony, irregular heart rate, and atrioventricular dissociation, have been demonstrated. The aim of this study was to investigate the effects of VES on the right ventricle (RV) using strain imaging. MATERIAL AND METHODS: Fifty patients with 5000 or more VES detected during 24hr Holterrhythm monitoring between April 2022 and September 2022 in the cardiology outpatient clinic were included in this study.A volunteer control group of 50 individuals matching the patients' age and demographic characteristics was selected. Right heart function parameters were compared echocardiographically between the two groups. RESULTS: In the VES group, both RV free wall strain (22.03±3.67, 29.52±3.01; p<0.001) and RV four-chamber strain (19.37±2.95, 22.34±2.11; p<0.001) were lower compared to the control groupIn the univariate regression analysis for decreased RV four-chamber strain, the presence of VES (p<0.001) was identified as a predictor, whereaas in the multivariate regression analysis, it was not considered to be an independent predictor. When evaluating the characteristics of the VES patients, the number of VES detected during Holter monitoring and delta QRS were observed as negative predictors of RV strain. CONCLUSION: This study demonstrated the adverse effects of VES on the right ventricle, as it is on the left ventricle.Therefore, regular monitoring of RV function with echocardiography is important in the follow-up of patients with VES.

Özderya et al. (2024) conducted an observational in Ventricular extrasystoles (n=100). Ventricular extrasystoles (≥5000/24h) vs. Healthy volunteers without clinical symptoms of arrhythmia and without VES was evaluated on Right ventricle (RV) four-chamber strain (p=<0.001). Ventricular extrasystoles (≥5000/24h) were associated with significantly reduced right ventricle four-chamber strain (19.37 vs 22.34, p<0.001) compared to healthy controls.
