Study offers novel insight into cardiac arrhythmias, sudden cardiac death

A new study by researchers at Rhode Island Hospital provides much-needed insight into the molecular mechanisms that cause arrythmia, or irregular heartbeat, and how it triggers sudden cardiac death, one of the nation’s leading killers. Their findings, published online in the Journal of Clinical Investigation, could pave the way for the development of new, genetically-targeted therapies to treat and prevent fatal arrythmias.
