Anna Pfenniger is a Northwestern University physician-scientist who combines cardiac electrophysiology practice with basic and translational research on abnormal heart rhythms. She earned an MD in 2008 and PhD in 2012 from the University of Geneva, completed cardiovascular research postdoctoral training at New York University in 2013, internal medicine residency at the University of Massachusetts in 2016, and cardiology and clinical cardiac electrophysiology fellowships at Northwestern in 2019 and 2021. Her laboratory studies communication among atrial cell types, atrial fibrillation, and gene variants such as titin truncations, using patient data and experimental models. Clinically, she treats a broad range of rhythm disorders, with particular focus on familial or early-onset atrial fibrillation, and performs ablation and device procedures. She is an Assistant Professor of Medicine in Cardiac Electrophysiology and serves on professional editorial and award committees.
