APPARATUS FOR MONITORING A PERSON'S HEART RATE AND/OR HEART RATE VARIATION; WRIST-WATCH COMPRISING THE SAME
First Claim
1. Monitoring apparatus for monitoring a user'"'"'s heart, the apparatus comprising:
- at least one sensor for measuring changes in at least one electrical parameter of one of the user'"'"'s limbs, particularly an arm, from which changes an electrocardiogram, heart rate and/or heart rate variation of the user'"'"'s heart are determinable;
a data processor for determining the electrocardiogram, the heart rate and/or heart rate variation from the changes in the at least one electrical parameter; and
an output device for auditively and/or visually making knowable to the user the electrocardiogram, heart rate and/or heart rate variation, wherein the apparatus is configured to position the at least one sensor at or near a surface of the user'"'"'s limb, particularly to measure the changes in the at least one electrical parameter of the user'"'"'s limb via the surface of the user'"'"'s limb, wherein at least one of the sensors comprises a capacitor having two capacitor electrodes placeable at positions on substantially opposite sides of the limb during use, the at least one electrical parameter comprising a permittivity of the limb, wherein the capacitor is arranged such that in use, a capacitance of the capacitor is sensitive to pressure pulses in at least one blood vessel of the limb.

Abstract
Monitoring apparatus (4) for monitoring a user'"'"'s heart, the apparatus comprising several sensors (14, 16) for measuring changes in an electrical parameter of a user'"'"'s arm (20), from which changes in an electrocardiogram, heart rate and/or heart rate variation of the user'"'"'s heart are determinable. The apparatus further comprises a data processor (28) for determining the electrocardiogram, the heart rate and/or heart rate variation from the changes in the electrical parameter; and an output device (32) for making knowable to the user the electrocardiogram, heart rate and/or heart rate variation. A basic idea of the present invention is, to use only a single wristband, particularly a wrist watch, having all the means to monitor the user'"'"'s heart, without using for example a chest band. Herein, the single wristband is at least provided with the at least one sensor and particularly also comprises the data processor, and more particularly also comprises the output device.
