Apparatus and method for detecting atrial fibrillation
First Claim
1. A method for detecting atrial fibrillation, comprising repetitively obtaining a plurality of groups of n successive RR intervals from a patient'"'"'s heart potentials, n being a natural number greater than 1, defining a plurality of points in an n-dimensional space of numbers, each point representing one of said groups of n successive RR intervals, to form a characteristic distribution of said points, comparing said characteristic distribution with at least one normal distribution derived from a healthy heart, and generating at least one state signal representing the state of the heart from said deviation.

Abstract
A lightweight, battery-operated, voltage-stabilized, bioelectronic and non-invasive measuring apparatus derives the electrical heart potentials using measuring electrodes fixed to the patient and uses electronic numerical evaluation to produce therefrom an electronic risk display for safely diagnosing atrial fibrillation at the earliest possible time in the illness.
