Implementation of portable monitor based on mobile phone for music therapy on hypertension

Hypertension is a common clinical disease and a major risk to human health. Relationships between specific music phrases and cardiovascular variability promote music therapy to an important part of anti-hypertension treatment. We integrate our former related researches achievement into a new portable monitor based on smart phone. The new portable device which is made up of health accessories and mobile software, can measure user's blood pressure (BP) with a cuff-less technique, do data processing, display waveforms and parameters and play selected music. The strategy of music selection is based on correlation coefficient, which derived from rhythm of music phrases and blood pressure. The coefficient determines the type of music should be selected and played.
