Heart rhythm study aims to end guesswork in AFib ablation

This study looked at a common heart rhythm problem called atrial fibrillation (AFib). Doctors wanted to find better ways to predict which patients would benefit from a procedure called ablation, which creates scar tissue in the heart to stop abnormal rhythms. The study planned to use advanced heart mapping, MRI scans, and blood tests to create a prediction tool. Only one person enrolled before the study was stopped, so no conclusions could be drawn.
