Jane Chen, M.D., assistant professor of medicine, demonstrates to Bill Katsiyiannis, M.D., a cardiologist and electrophysiologist with the Minneapolis Heart Institute and a former WUSTL fellow, how to implant a pacemaker on a dummy model. The lesson for cardiology fellows was held July 21-22 on Medtronic’s 18-wheeler Mobile Cath Lab at the Chase Park Plaza, and provided fellows with hands-on experience in implanting techniques. The program had 35 fellows who came from as far away as West Virginia.
