Researchers find that electrical function may be restored in
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. The finding was recently published in Proceedings of the National Academy of Sciences.

"This is the first direct evidence that electrical connections between scar and healthy tissue occur in the heart," says Dr. Alex Quinn, assistant professor in the Department of Physiology & Biophysics. "This finding really turns our current understanding of the heart's electrical activity on its head, and may open the door to much needed improvements in treating many cardiac diseases."
