Imad Libbus, Paul A Haefner, Aaron McCabe, Yi Zhang: Method and apparatus for synchronizing neural stimulation to cardiac cycles. Cardiac Pacemakers, Schwegman Lundberg & Woessner P A, June 2, 2009: US07542800 (108 worldwide citation)

A neural stimulator senses a reference signal indicative of cardiac cycles each including a predetermined type timing reference event using a sensor external to the heart and blood vessels. The delivery of the neural stimulation pulses are synchronized to that timing reference event. Examples of the ...

Paul A Haefner, Gary Thomas Seim: Cardiac rhythm management system with cross-chamber soft blanking. Cardiac Pacemakers, Schwegman Lundberg Woessner & Kluth P A, January 2, 2001: US06169918 (91 worldwide citation)

A cardiac rhythm management system provides cross-chamber “soft blanking.” It senses desired electrical heart activity signals associated with a first chamber electrode while reducing unwanted signals (paces and depolarizations) associated with a second chamber of the heart. Detection of a cross-cha ...
