Many physical processes have distributions of times between events that have non-normalizable, power law probability density functions ͑PDF's͒. The moments of such distributions are not defined. We found that the PDF's of the times between events of ventricular tachyarrhythmia ͑rapid heart rate͒ and premature ventricular contractions have a power law form(More)
The well-studied methods of current source density analysis use the Laplacian transform to identify locations and relative magnitudes of current sources and sinks. The method is typically used in reduced one-dimensional form for electrophysiological measures, due to technical limitations. The present paper outlines a two-dimensional method in which(More)
