What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)

Summary

This study compares a new pacing technique (His bundle pacing) to standard right ventricular pacing in 100 adults with symptomatic atrial fibrillation and heart failure who are having AV node ablation. The goal is to see if the new method helps them walk farther, feel better, and be more active. Participants will wear a Fitbit to track daily steps and distance.
