Patent number: 10029103Abstract: A system and method for cardiac resynchronization therapy (“CRT”) in which a model of baseline cardiac electrical activity, such as a model of global baseline cardiac electrical activity derived from various surface electrocardiograph (“ECG”) signals, is utilized to automatically adjust pacing control parameters of a cardiac implantable electrical device (“CIED”) are provided. The baseline model is compared to CRT response patterns using modified pacing control parameters in an iterative fashion, based on a patient-specific response pattern phenotype determination, until ventricular electrical asynchrony is minimized. The pacing control parameters resulting in the minimum ventricular electrical asynchrony are used to generate final control parameters for CRT.Type: GrantFiled: July 16, 2012Date of Patent: July 24, 2018Assignee: THE BRIGHAM AND WOMEN'S HOSPITALInventor: Michael O.

Patent number: 9265951Abstract: A system and method for cardiac resynchronization therapy in which pacing control parameters are automatically adjusted by comparison of local electrograms acquired by a cardiac implantable electrical device with a model of cardiac electrical activity derived from surface-lead electrocardiograph measurements under baseline and paced conditions is provided. The adjusted pacing control parameters guarantee substantially maximum evidence of ventricular activation wavefront fusion while reducing the risk of compromising diastolic function.

Patent number: 8805504Abstract: A system and method for cardiac resynchronization therapy (“CRT”] in which a model of baseline cardiac electrical activity, such as a model of global baseline cardiac electrical activity derived from various surface electrocardiograph (“ECG”) signals, is utilized to automatically adjust pacing control parameters of a cardiac implantable electrical device (“CIED”) are provided. The baseline model is modified with simulated pacing control parameters in an iterative fashion until ventricular electrical asynchrony is minimized.

Patent number: 8265750Abstract: An implantable pacing system with single, double and triple chamber pacing capabilities, provided individually or in concert on a conditional or continuous basis depending upon ongoing analyses of atrial rhythm status, atrioventricular conduction status and ventricular rate. A mode is selected to reduce the occurrence of any ventricular pacing in favor of intrinsic atrioventricular and ventricular conduction. If excessively long PR intervals are occurring too frequently or atrioventricular conduction is unreliable or absent, the implantable pulse generator is operated in a conditional triple chamber pacing mode that provides atrial-synchronous biventricular pacing in every cardiac cycle for a period of time as necessary to restore and maintain AV synchrony, while minimizing ventricular asynchrony otherwise associated with monochamber RV pacing as in conventional dual chamber pacing systems.Type: GrantFiled: February 26, 2010Date of Patent: September 11, 2012Assignee: Medtronic, Inc.Inventors: Michael O.

Patent number: 8032216Abstract: An atrial based pacing protocol promotes intrinsic conduction. An entire cardiac cycle is monitored for ventricular activity and permitted to lapse with ventricular activity. Ventricular pacing is available in a cardiac cycle immediately subsequent to such a skipped beat. When monitoring for intrinsic ventricular events, an event is expected within a given window. If no such event is detected, the cardiac cycle is truncated, leading to a shorter cycle that is devoid of ventricular activity. The subsequent cycle has a high likelihood of a ventricular sensed event and a greater than normal AV interval is provided prior to pacing.Type: GrantFiled: January 11, 2011Date of Patent: October 4, 2011Assignee: Medtronic, Inc.Inventors: Todd J. Sheldon, Paul A. Belk, Michael O. Sweeney
