MINNEAPOLIS & DENVER--(BUSINESS WIRE)--Medtronic, Inc. (NYSE: MDT) today released new evidence demonstrating that key shock-reduction programming strategies significantly reduced implantable cardioverter-defibrillator (ICD) and cardiac resynchronization therapy defibrillator (CRT-D) shocks from 17 to 28 percent. The study also identified programming and patient characteristics that increased the risk of shocks. These results, which were from the largest study of its kind, with nearly 89,000 patients from more than 2,500 centers, further validate the value of shock-reduction device programming strategies. The findings were released during the Late-Breaking Clinical Trials Session at Heart Rhythm 2010, the Heart Rhythm Society’s 31st Annual Scientific Sessions.
