VFA CARDIAC RESYNCHRONIZATION THERAPY USING ACCELEROMETER

Abstract: an implantable medical device includes a plurality of electrodes to detect electrical activity, a motion detector to detect mechanical activity, and a controller to determine at least one electromechanical interval based on at least one of electrical activity and mechanical activity. the activity detected may be in response to delivering a pacing pulse according to an atrioventricular (av) pacing interval using the second electrode. the electromechanical interval may be used to adjust the av pacing interval. the electromechanical interval may be used to determine whether cardiac therapy is acceptable or whether atrial or ventricular remodeling is successful.
