Arrangement for predicting tacharrhythmia

摘要

An arrangement 10 for predicting tachyarrhythmia of a heart has a detection means 12 and an evaluation unit 18. The detection means 12 picks up electrical signals from the heart. The evaluation unit 18, which is connected to the detection means, determines a rate value that depends upon the respective heart rate. The evaluation unit also evaluate a plurality of correspondingly determined rates values, to determine a heart rate variability value that depends on the variability of the detected rate values, wherein the evaluation unit 18 responds to a rise in the heart rate variability value.
