December 4, 2007 - Two special electrocardiograms (EKG) can help predict heart-related death or cardiac arrest after a heart attack, according to Canadian scientists.
One EKG checks the heart's nervous system and the other the heart’s electrical system. By combining the results of both tests, given 10-14 weeks after a heart attack, was the study's best predictor of heart-related death or cardiac arrest requiring resuscitation.
