American Heart Association says many sudden cardiac arrests preceded by warning signs
December 4, 2013
Dallas, TX – Sudden cardiac arrest isn’t always so sudden, according to research presented at the American Heart Association’s Scientific Sessions 2013.
In a study of middle-age men in Portland, Oregon, more than half had possible warning signs up to a month before their hearts stopped abruptly.
Cardiac arrest occurs when the heart stops due to a failure in its electrical system. Patients can sometimes survive if they receive CPR immediately and a defibrillator is used quickly to shock the heart into a normal rhythm.
