Kind: research · Impact: medium

## In brief

- In people with heart block, left bundle branch pacing (LBBP) was associated with lower rates of death, heart failure hospitalization and pacing-induced cardiomyopathy than right ventricular pacing.
- The international randomized OptimPacing trial was stopped early because the results showed superiority for LBBP, according to MedPage Today.
- The findings were reported in coverage of a meeting presentation (AHA), per the MedPage Today article.

## Why it matters

The results suggest LBBP may be a better pacing option than right ventricular pacing for patients with atrioventricular block, which could influence clinical practice and guidelines once full data are published.
