A man working in New Jersey was nearly killed when he was shocked by high-voltage transmission lines.  A police officer was able to get the worker’s heart beating again through CPR. “They start compressing on the chest and supplying oxygen -- and that might have been enough to re-set the rhythm and regain normal electric activity,” said Daniel Edmundowicz, chief of cardiology at Temple University Hospital.  “Fortunately, it sounds like he was not without oxygen for a long period of time.”
