Caption

A noninvasive cardiac map shows the electrical signals of a single beat. The gray area is a scar from a prior heart attack. The electrical signals that cause ventricular tachycardia enter the scar at the blue area, follow the yellow arrow along the border of the scar and exit the scar at the red area.
