Abstract
Abstract A method for interactively entraining a patient's heart rate to a target rate or frequency includes the steps of determining the patient's heart rate through a heart rate monitor and exposing the patient to music having a tempo within approximately one (1) beat of the heart rate. The heart rate is again determined, and if it has changed the tempo of the music is likewise changed in order to be within approximately one (1) beat of the heart rate. The process is continued until the target rate is reached. Vibrational bass tones can be added to enhance the entrainment. Similar methods can be used to entrain respiration rate and fundamental brain wave frequencies, in the latter case using continuous tones of music having repetition frequencies within the entrainment range.
