Summary
This study tested a surgery that cuts certain heart nerves to control life-threatening fast heartbeats in people with Chagas heart disease. 45 patients who already have an implanted defibrillator and had at least four shocks in the past six months were randomly assigned to get the nerve surgery, standard catheter ablation, or just medication. The goal was to see if the surgery could reduce the number of dangerous rhythm episodes and improve quality of life.
