Abstract: <P>PROBLEM TO BE SOLVED: To estimate a frequency of a sampled cardiac rhythm signal and classify the rhythm.  <P>SOLUTION: The received signal is sampled and transformed into a curvature series. A lobe in the curvature series corresponds to a characteristic point in the sampled series. Characteristic points are selected based on a time of a lobe in the curvature series and, in one embodiment, an amplitude of the signal at the time of the lobe. A frequency of the sampled series is estimated by autocorrelating a function of the series of the characteristic points. In one embodiment, the function is a time difference function.
