First patient given pacemaker that can beat fainting attacks - The Times Online - 9th January 2008

A London hospital has become the first in the world to implant a new generation of pacemaker designed to prevent fainting. A 65-year-old man from West London was fitted with the device under local anaesthetic at St Mary’s Hospital this week. The Biotronik Cylos 990 pacemaker detects subtle changes in the body before a fainting episode and then works to prevent it. Fainting occurs when the bloodflow to the brain is reduced. One in three people is thought to experience fainting, but some have frequent blackouts that disrupt their lives seriously.
