Abstract
Heart monitoring apparatus with sensing stage connectable to intracardiac electrode picking up electric potentials and adapted to process electric signals representing a time course of said potentials, a mechanical action detection stage adapted to generate a geometry signal having a time course reflecting heart chamber's geometry change, an evaluation unit connected to sensing stage and impedance measuring stage and adapted to determine a first and second fiducial point in the time course of said potentials and geometry signal, respectively, both fiducial points belonging to same heart cycle, and to determine a measured time delay between said fiducial points. Evaluation unit adapted to repeat said determined time delay to determine plurality of measured time delays and variance thereof or divergence of the statistical properties of cycle times based on said time course of said electric potentials versus cycle times based on said time course reflecting a change of a heart chamber's geometry.
