Title: CARDIAC RESYNCHRONIZATION USING FUSION PROMOTION FOR TIMING MANAGEMENT
Abstract:
Methods, systems and devices for providing cardiac resynchronization therapy (CRT) to a patient using a Ieadless cardiac pacemaker and an extracardiac device. The extracardiac device is configured to analyze one or more QRS complexes of the patient's heart, determine whether fusion pacing is taking place, and, if not, to communicate with the Ieadless cardiac pacemaker to adjust intervals used in the CRT in order to generate desirable fusion of the pace and intrinsic signals. The extracardiac device may take the form of a subcutaneous implantable monitor, a subcutaneous implantable defibrillator, or other devices including wearable devices.
