Virus rebuilds heart’s own pacemaker

16 December 2012 Last updated at 13:05 ET By James Gallagher Health and science reporter, BBC News A new pacemaker has been built inside a heart by converting beating muscle into cells which can organise the organ’s rhythm, US researchers report. The heartbeat is controlled by electrical signals and if these go awry the consequences can be fatal. Scientists injected a genetically-modified virus into guinea pigs to turn part of their heart into a new, working pacemaker. Continue reading
