APPARATUS FOR MONITORING A PERSON'S HEART RATE AND/OR HEART RATE VARIATION; WRISTWATCH COMPRISING THE SAME

摘要

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 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 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.
