New heart mapping could stop deadly rhythm episodes in their tracks

This study tests a new way to find and destroy the diseased heart tissue causing ventricular tachycardia (VT), a life-threatening fast heart rhythm. About 77 adults with heart disease and an implanted defibrillator will undergo a standard ablation procedure, but guided by a novel mapping method called DeEP. Researchers will check if the new approach stops VT episodes during the procedure and over the next year, aiming to improve long-term control of this dangerous condition.
