MINNEAPOLIS & DENVER--(BUSINESS WIRE)--Medtronic, Inc. (NYSE: MDT) released the Virtual ICD study data today that predicted 98 percent of studied implantable defibrillator patients would be free of inappropriate shocks one year after implant and 92 percent at five years post-implant. The Virtual ICD study used a statistical model that predicts that six advanced shock-reduction algorithms for implantable cardioverter-defibrillators (ICDs) and cardiac resynchronization therapy defibrillators (CRT-Ds) can reduce inappropriate shocks experienced by patients. The results were significant. The findings were released during Heart Rhythm 2010, the Heart Rhythm Society’s 31st Annual Scientific Sessions.
