Summary:An apparatus and method for brachytherapy. One method includes locating a region of cardiac tissue having a relatively large probability of originating or transmitting electrical signals which result in arrhythmic activity and irradiating the region of cardiac tissue to reduce the amount of arrhythmic activity. Irradiating can include regulating protein expression of myocardial cells, killing myocardial cells, ablating myocardial cells, irradiating sleeves of atrial muscle that extend from a left atrial wall around the pulmonary veins, and/or creating lesions that block electrical conduction through myocardial tissue. Locating the region can include locating a foci of an atrial arrhythmia or locating the foci adjacent a pulmonary vein.
