Methods for Sonic Representation of Heart Rate During Exercise

Sonic display of HR changes during exercise helps both the patient and the investigator to better identify the transition from rest values to "exercise" zone. then crossing the "attention" threshold and reaching the "alert" threshold. Three types of sonic display were tested, based on combinations of saccadic sounds, different intensities and different pitch. The results indicate a clear preference towards a display marking each of the four zones by a specific pitch.
