Heart monitor
First Claim
1. A heart rate monitor apparatus including a monitoring part comprising a plurality of recording electrodes each incorporated into a contact surface for application to an external body surface of a human or animal subject and a means for acquisition of data from the electrodes, a data processing part comprising a means for conversion of acquired analogue to digitised data, a means for analysing the digitised data to produce an output, and optionally a display part to display a result corresponding to the output, wherein the means for analysing the digitised data includes means to process the data by way at least of the steps of producing a frequency and/or signal intensity based data characterisation and inferring and outputting therefrom a result representative of the heart beat rate of the subject.

Abstract
A heart rate monitor apparatus and method are described. The apparatus consists of multiple recording electrodes each incorporated into a contact surface for application to an external body surface of a human or animal subject and a data acquisition and processing system to process the data by way at least of the steps of producing a frequency and/or signal intensity based data characterisation and inferring and outputting therefrom a result representative of the heart beat rate of the subject. In particular the data processing method involves deriving the result by identifying a peak in the frequency and/or by signal intensity based data characterisation for example by producing a power density spectrum, identifying the peak power frequency and, outputting the result as a result representative of the heart beat rate of the subject.

15. A method for the measurement of heart rate, especially for the purposes of monitoring or diagnosis, comprising:
-
attaching a plurality of recording electrodes to an external body surface of a human or animal subject;
acquiring data therefrom corresponding to internal electrical activity measured at the surface;
immediately or subsequently processing the acquired data by;
digitising the data;
analysing the data by producing a frequency and/or signal intensity based data characterisation;
inferring and outputting therefrom a result representative of the heart beat rate of the subject. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22)
