Abstract
A heart rate monitor for use with exercise equipment to calculate the user's heart rate while exercising. The monitor includes only two, first and second, electrodes and a signal processor. The first electrode is disposed at a first location on the exercise equipment for contacting the user and for sensing the user's heart rate. The first electrode produces a first sensed signal representative of the user's heart rate. The second electrode is disposed at a second location on the exercise equipment for contacting the user and for sensing the user's heart rate. The second electrode produces a second sensed signal representative of the user's heart rate. The signal processor produces a difference signal indicative of a difference between the first and second sensed signals. The signal processor further includes a power spectrum analyzer calculating the user's heart rate by measuring the power spectrum of the difference signal and producing a processed heart rate signal as a function of the measured power spectrum whereby the processed heart rate signal is indicative of the heart rate of the user as sensed by the first and second electrodes. A method of monitoring the heart rate of a person is also included.
