Abstract
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 heart rate. By adjusting the interval between paces as a function of heart rate, the atria and/or ventricles may be activated in a more synchronous and more hemodynamically efficient fashion.
Claims36
An implantable medical device system comprising:
- a pulse generator that delivers a first pacing pulse to a first cardiac chamber of a heart and a second pacing pulse to a second cardiac chamber of the heart following a pacing interval;
- and
- a processor that selects the pacing interval as a function of a heart rate,
- wherein the first cardiac chamber and the second cardiac chamber are complementary cardiac chambers.
1 more element
A method comprising:
- selecting a pacing interval as a function of a heart rate;
- delivering a first pacing pulse to a first cardiac chamber of a heart;
- and
- delivering a second pacing pulse to a second cardiac chamber of the heart following the pacing interval;
- wherein the first cardiac chamber and the second cardiac are complementary cardiac chambers.
2 more elements
A computer-readable medium comprising instructions that cause a processor to:
- select a pacing interval as a function of a heart rate;
- deliver a first pacing pulse to a first cardiac chamber of a heart;
- and
- deliver a second pacing pulse to a second cardiac chamber of the heart following the pacing interval;
- wherein the first cardiac chamber and the second cardiac are complementary cardiac chambers.
2 more elements
An implantable medical device system comprising:
- means for delivering a first pacing pulse to a first cardiac chamber of a heart of a patient and a second pacing pulse to a second cardiac chamber of the heart following a pacing interval;
- and
- means for selecting the pacing interval as a function of a heart rate,
- wherein the first cardiac chamber and the second cardiac are complementary cardiac chambers.
