Zusammenfassung:	Reduced Atrial Tachyarrhythmia Susceptibility After Upgrade of Conventional Implanted Pulse Generator to Cardiac Resynchronization Therapy in Patients With Heart Failure Demetris Yannopoulos, Keith G. Lurie, Scott Sakaguchi, Simon Milstein, Cengiz Ermis, Laura VanHeel, David G. Benditt Atrial tachyarrhythmia (AT) frequency and characteristics were compared before and after upgrade of conventional dual-chamber pulse generators to cardiac resynchronization therapy (CRT) defibrillators in patients being treated for heart failure (HF) associated with left ventricular systolic dysfunction. Each patient served as his/her own control. In follow-up >1 year, CRT upgrade was accompanied by reduced AT frequency and duration and fewer HF and arrhythmia hospital stays. Thus, CRT might ameliorate susceptibility to AT in HF patients.
