Also, an electronic device which generates audio signals can be provided. The image and the audio signals can be formed without any connection with heart beat of a person whose heart activity is monitored, thus serving only entertaining and distracting purposes. On the other hand, the image and the audio signals can be formed in response to and in correspondence with heart beat of a person whose heart activity is monitored so as to provide an additional visual and audio information about his or her heart activity. | |
