'Heart Massage Pace' tells you the pace of heart massage by the display, sound and vibration.
(At first, the vibration function is turned off.)
The pace can be adjusted between 80 and 120 times/min.
(At first, 100 times/min)
This application simply gives you only the pace that you set (or default setting), not the way of heart massage.
And this application is for study and enlightenment for heart massage, not for practical use.
So please study the method of the heart massage on the technical book or the website or from the specialist beforehand by yourself.
The pace of heart massage influences the effect of it, so be careful of the setting of the pace enough.
I do not take the responsibility for the result of heart massage with this application.
