First of all, you must never put the TENS pad on top of the heart, it will affect the heartbeat. For example for running the Spooky2 program for mitral valve prolapse, usually the best place to use the TENS pad is on both sides of the stomach, the stomach/gut, because the stomach/gut has as much information about the body as the brain does , the frequency can reach the viscera to which it belongs. In addition, they can also be placed on related meridian acupuncture points, such as the heart meridian and the heart cell meridian, to obtain therapeutic effects.
