Warren L Vanhout: Adjustable cardiac resynchronization. Medtronic, Paul H McDowall, Girma Wolde Michael, January 11, 2005: US06842642 (31 worldwide citation)

Techniques are presented for providing adjustable cardiac resynchronization with an implanted medical device such as a pacemaker. For example, cardiac resynchronization may be provided during some time periods but not during other time periods, or cardiac resynchronization may be provided in respons ...

Warren L VanHout: Method and apparatus for monitoring conduction times in a bi-chamber pacing system. Medtronic, Medtronic, January 16, 2003: US20030014084-A1

Multi-site cardiac pacing systems that pace and sense in at least a first site in the heart and sense conducted electrical signals at a second site in the heart and measure and accumulate electrical conduction times between the first and second sites to derive trend data indicative of the state of h ...
