Gregory
M. Marcus, MD is
Assistant Professor of Medicine. His clinical activities center on
the treatment of arrhythmias, including mapping and catheter ablation
for atrial fibrillation, supraventricular tachycardias, and ventricular
arrhythmias. He also performs implantation of pacemakers, biventricular
devices, and defibrillators. His previous research focused on the
cardiac physical exam. While maintaining a focus on the clinical
presentation of cardiovascular disease with an emphasis on arrhythmias,
his current primary research involves an examination into the etiologies
of atrial arrhythmias, specifically analyzing serologic markers and
genetic determinants important to the atrial substrate in atrial
fibrillation.
