Abstract

A rate-changing implantable heart-stimulating device is disclosed, one that avoids use of moving parts and making unwanted rate changes. The device senses and responds to skeletal myopotential signals derived from the body of the wearer, preferably considering both amplitude and frequency of myopotential voltage signals which exceed a predetermined threshold value. The device preferably has two-way radio communication with an external programmer means.
