CARDIAC RESYNCHRONISATION WITH ADAPTIVE A1-A2 AND/OR V1-V2 INTERVALS |
摘要 |
In a system that provides bi-atrial and/or bi-ventricular pacing, the system adjusts an interval between paces delivered to the atria, and/or an interval between paces delivered to the ventricles, as a function of pressure data from the heart. In an exemplary embodiment, the system uses the pressure data from the ventricles to identify the times that each ventricle begins ejection of blood. The system may adjust the interval between paces to cause the ventricles to begin ejection at the same time, or to cause one ventricle to commence blood ejection prior to the other ventricle with a desired time offset. The system may further adjust the interval in response to changing conditions, such as a changing heart rate.
