Abstract
Illustrative devices and methods may provide cardiac resynchronization therapy (CRT) that utilizes transient CRT settings to mitigate right ventricular load during implementation of the CRT. The transient CRT settings may increase in aggressiveness until reaching target CRT settings. Further, the transient CRT settings may decrease in aggressiveness in response to ventricular deterioration.
Claims28
An implantable medical device comprising:
- an electrode apparatus comprising one or more electrodes configured to deliver cardiac resynchronization therapy (CRT) to a patient's heart using CRT settings and to sense electrical activity of the patient's heart;
- and
- a computing apparatus operably coupled to the electrode apparatus and comprising processing circuitry, the computing apparatus configured to:
- deliver CRT according to transient CRT settings to the patient's heart using the one or more electrodes, wherein the transient CRT settings are less aggressive than target CRT settings to partially optimize left ventricular functionality to mitigate right ventricular load;
- and
- transition from the transient CRT settings to the target CRT settings over a transition time period.
