Abstract
An implantable medical device uses a sampling scheme to obtain digital representation from analog signals. The analog signals represent intracardiac activity. Generally, a detector detects the amplitude of the analog signals and generates first and second difference signals. The first difference signal is generated after detection of significant changes in the analog signal amplitude. The second difference signal is generated upon confirmation of the absence of significant changes in the analog signal amplitude over a predetermined period of time. A frequency selection is implemented to select the sampling frequency based on the first and second difference signal.
