the hypothesis that production of ischemia or cooling of an arrhythmogenic area or pathway could interrupt tachycardias was tested by subselective catheterization of the coronary artery supplying the site of origin of ventricular tachycardia ( 9 patients ) , the accessory pathway ( 2 patients ) and the site of origin of atrial tachycardia ( 1 patient ) .
