ABSTRACT:
Apparatus and method for testing the autonomic nervous system of a mammal through bi-variate analysis of heart period (RR) and QT interval variability obtained through data processing of electrocardiographic data. The method and apparatus enables both the parasympathetic and sympathetic controls on the heart to be evaluated for imbalances therebetween, which may indicate a predisposition for sudden cardiac death.
