Zak Loring

Associate Professor of Medicine
Medicine, Cardiology

Overview


I am a cardiac electrophysiologist specializing in the treatment of heart rhythm disorders and management of cardiac implantable electronic devices (CIEDs). My research utilizes signal processing of electrocardiographic data and novel analytic techniques to better phenotype patients and identify those for whom interventional electrophysiology procedures may be most beneficial. This includes predicting which patients with left bundle branch block may benefit from early cardiac resynchronization therapy or conduction system pacing. I also analyze population level data to identify patients at high risk for adverse sequelae of rhythm disorders who may benefit from early intervention.
