About me
Dr. Hadadi specializes in the evaluation and management of heart rhythm disorders, including atrial fibrillation, supraventricular tachycardia (SVT), and ventricular tachycardia. His clinical interests include special therapies such as epicardial catheter ablation for complex ventricular tachycardia, and developing new device-based interventional cardiac resynchronization therapies.
As Associate Director of Cardiac Arrhythmia Research, Dr. Hadadi is pioneering the application of advanced analytic techniques to large, complex patient data sets to improve outcomes for MedStar Heart & Vascular Institute cardiac electrophysiology procedures.
Philosophy of Care
“Patients are so much more than just a sum of cryptic medical diagnoses. They are beautiful human beings with luminous souls. At MedStar Heart & Vascular Institute, we put the heart back in heart care by treating each person by always prioritizing their dignity, humanity and individuality. The trust that my patients place in me to address every aspect of their cardiac arrhythmia needs is what brings me to work every morning with a smile on my face.” —Cyrus Hadadi
