Electrocardiographic apparatus for analyzing the function of a heart and for pacing the heart dependent on the analysis

摘要

A device for analyzing the function of a heart has an electrical measurement unit for generating a measurement signal related to an electrical or mechanical heart variable, and an evaluation unit for evaluating the measurement signal. The device further includes circuitry for generating at least one parameter signal from the measurement signal. The evaluation unit analyzes related values in the measurement signal and the parameter signal, these related values corresponding to coordinates which form a curve in a coordinate system, the measurement signal and the parameter signal serving as coordinate axes, by sensing the sequence in which the curve passes a predesignated number of areas in the coordinate system. The device is capable of detecting spontaneous and stimulated heartbeats, tachyarrhythmias, retrograde conduction, ectopic beats, etc.
