An acceleration measure for heart rate variability via Poincaré plot

Abstract

In this paper, an acceleration measure (AM) for heart rate variability (HRV) is presented. Via the quantitative index AM, the acceleration of change of the normal sinus rhythm can be described effectively. Experiment results demonstrate that via the higher distribution density of experiment results of normal sinus rhythm, the sinus rhythm can be recognized and classified effectively. Hence, AM can be as a valid feature of the sinus rhythm.
