Dr. Dickfeld is a leading electrophysiologist whose clinical practice spans all aspects of electrophysiology (heart rhythm management) including medical treatment, device therapy and extraction as well as atrial/ventricular arrhythmia management and ablation.

Dr. Dickfeld has a special interest in complex atrial and ventricular arrhythmias.

During his fellowship at Johns Hopkins Dr. Dickfeld developed a special expertise in cardiac imaging receiving multiple Young Investigator and Abstract Awards. At the University of Maryland he combined the two fields of electrophysiology and imaging to help develop the field of image-guided electrophysiology and better characterize the arrhythmia substrate and improve the clinical care of patients. His laboratory was the first to integrate functional imaging showing that positron emission tomography (PET) can be used to facilitate ablation for ventricular arrhythmias. Similarly, he was the first to demonstrate that 3D innervation maps can detect abnormalities in the heart muscle to guide the treatment of complex arrhythmias. Under his leadership the University of Maryland became one of the first centers to offer MRI to ICD patients to better guide the care and ablation for cardiac arrhythmias. In the largest available restrospective review Dr. Dickfeld demonstrated no clinical interactions between computed tomography and pacemakers/defibrillators adressing and providing evidence to adjust a FDA advisory for CT imaging in device patients.  Dr. Dickfeld’s work has been supported by multiple grants including the National Institutes of Health (NIH) and the American Heart Association (AHA). He has participated in multiple national and international multi-center trials and international registry collaborations.

Dr. Dickfeld is a nationally and internationally renowned electrophysiologist with over 100 peer-reviewed publications and over 200 peer-reviewed presentations and invited speeches. Due to his expertise Dr. Dickfeld was part of the writing committees of multiple national guidelines on sudden cardiac death, ventricular arrhythmias and cardiac imaging lead by the American Heart Association, American College of Cardiology and Heart Rhythm Society. He is a regular reviewer for multiple prestigious cardiac journals including Circulation, JACC, European Heart Journal, Circulation A&E, JACC EP and Heart Rhythm Journal. Dr. Dickfeld has been serving on several editorial boards of cardiac/electrophysiological journals and has been an active member of the Heart Rhythm Society Scientific and Clinical Document Committee.
