    Arrhythmia Specialists

    Physicians that specialize in treating conditions and diseases that result then the heart does not beats as it should are called electrophysiologists. Sometimes this long term is simplified to arrhythmia specialist or just EP.

    To become an electrophysiologist, a physician in training must first specialize in cardiology and become an expert on the heart and the circulatory system. Then, the physician completes a an additional electrophysiology fellowship specifically about the heart’s electrical system and heart rhythm disorders. Finally, to prove their expertise, they must pass a subspecialty board exam on arrhythmias.

    Only a small percentage of cardiologists have this level of subspecialty training. Four electrophysiologists currently treat arrhythmia patients at Mills Peninsula Hospital.

    Shaun Cho, M.D.

    Dr. Shaun Cho graduated from Cornell University in 1995 and did a cardiac electrophysiology fellowship locally at Stanford University, cardiovascular medicine. Dr. Cho has special experience in procedures that implant devices to help regulate the heart’s rhythm, such as pacemakers. His professional interests also include medical and interventional management of all adult cardiac arrhythmias, including complicated ablation and atrial fibrillation ablation procedures.

    Sung H. Chun, M.D.

    Dr. Chun earned his medical doctorate in 1989 at George Washington University School of Medicine in Washington, DC. He then came west to complete his internship and residency training at the University of California, Los Angeles (UCLA) and VA West Los Angeles Medical Center before going on to Stanford University Medical Center for his fellowship training in cardiology and electrophysiology. He is known for his expertise in laser lead extraction, a method of carefully removing old wires (leads) when new pacemakers or other implanted are inserted. In addition, his professional interests include resynchronization therapy, which is treating congestive heart failure with special pacemakers to coordinate the beating of the heart.

    Girish Narayan, M.D.

    Dr. Narayan graduated from Harvard Medical School in 1995. He moved to the Silicon Valley area to complete fellowships in cardiology, cardiac imaging and cardiac electrophysiology at Stanford University. He has a special interest in advanced imaging techniques used in the diagnosis and treatment of heart disorders. This includes an interest in complex ablations for atrial fibrillation and imaging guided electrophysiology procedures, like those performed with the advanced stereotaxis system.

    Alan Schwartz, M.S., M.D., FACC, FACP FAHA

    Dr. Schwartz earned his medical degree at Tufts University in Boston, Mass. He completed his fellowship in cardiovascular disease at the University of California, San Francisco, where he also completed a fellowship in electrophysiology at the University's Cardiovascular Research Institute. His special interests include internal cardiac defibrillator and pacemaker implantation, as well as catheter ablation of cardiac rhythm disturbances, which he frequently performs using the advanced stereotaxis system.
