A Dalhousie Medical School researcher has discovered that scar tissue -- like that caused by a heart attack -- can maintain electrical function in damaged regions of the heart. Until now, scars in the heart were thought to only disrupt the electrical activity needed for a normal heart beat.

This finding, made by Dr. Alex Quinn of the Department of Physiology & Biophysics, could have significant implications for rehabilitating cardiac patients.
