Tongue pacemaker for snoring successfully implanted Posted: 14 Aug 2012 07:02 AM PDT The first tongue pacemaker was implanted Europe-wide that prevents pauses in breathing during sleep and helps protect against snoring. Physicians used the device for a patient who suffers from obstructive sleep apnea syndrome. In this, at times life-threatening illness, pauses in breathing can occur when the upper throat muscles are excessively relaxed during sleep. As a result, parts of the respiratory tract narrow and the person has difficulty breathing. The typical snoring noises occur when the affected person tries with great effort to get air through the blocked airways.
