Heart rhythm showdown: ablation may beat defibrillator for some patients

This study looks at two ways to treat a fast, dangerous heart rhythm called ventricular tachycardia in people with coronary artery disease and relatively good heart function. One treatment uses a catheter to burn the tiny area causing the problem (radiofrequency ablation), and the other uses a small device implanted in the chest to shock the heart back to normal (defibrillator). The goal is to see which approach leads to fewer serious events like death or hospital visits over three years. About 268 adults with a history of heart attack and a preserved pumping ability will take part.
