Secure and efficacious therapy delivery for an extra-systolic stimulation pacing engine |
June 19, 2007 |
| An extra-systolic stimulation (ESS) therapy addresses cardiac dysfunction including heart failure. ESS therapy employs atrial and/or ventricular extra-systoles via pacing-level stimulation to a heart. These extra-systoles must be timed correctly to achieve beneficial effects on myoca |

Atrial tracking recovery to restore cardiac resynchronization therapy in dual chamber tracking m |
May 3, 2005 |
| A feature named "atrial tracking recovery" (ATR) provides for restoring delivery of cardiac pacing therapy upon identification of an atrial refractory sense-ventricular sense (AR-VS) pattern of cardiac activity. In one embodiment, such patterns are monitored to determine if they are |

Cardiac pacing system delivering multi-site pacing in a predetermined sequence triggered by a se |
September 24, 2002 |
| A system for pacing in a right and its corresponding left heart chamber provides a predetermined or programmable triggered delay in a predetermined or programmable, right-to-left or left-to right sequence without first determining from which of the two chambers a triggering event ori |
