Abstract

An implantable medical device operates with an algorithm that promotes intrinsic conduction and reduces ventricular pacing. The IMD monitors the occurrence of necessary ventricular pacing and takes certain actions based upon whether this occurrence has been relatively high or relatively low. When noise is detected, asynchronous pacing is provided when the occurrence is relatively high and is not provided when relatively low. When atrial threshold testing is performed, the incidence will determine which methodology is utilized.

Claims

1. An implantable medical device (IMD) comprising:

means for operating the IMD with a Ventricular Pacing Protocol (VPP);

means for providing cardiac pacing;

means for selectively operating the IMD to inhibit or provide asynchronous pacing when noise is detected by the IMD, based upon a patient classification.

2. The IMD of claim 1, further comprising:

means for recording data regarding ventricular pacing during operation of the IMD with the VPP.

3. The IMD of claim 2, further comprising:

means for classifying a patient based upon the recorded data.

4. The IMD of claim 3, wherein the means for classifying classify the patient based upon a percentage of cardiac cycles requiring ventricular pacing into a first classification and a second classification, wherein the first classification includes a lower percentage of ventricular pacing than the second classification.

5. The IMD of claim 4, wherein the IMD inhibits asynchronous pacing when noise is detected and the means for classifying indicate the first classification and the IMD provides asynchronous pacing when noise is detected and the means for classifying indicate the second classification.

6. The IMD of claim 4, further comprising:

means for selecting a first atrial capture management (ACM) algorithm for when the means for classifying indicate the first classification and selecting a second ACM algorithm when the means for classifying indicate the second classification.

7. The IMD of claim 6, wherein the first ACM algorithm is an AV conduction algorithm and the second ACM algorithm is an atrial chamber reset algorithm.
