My focus is on heart rhythm problems. As a doctor, I work with patients to come up with a treatment plan that helps manage their condition. This may involve a cardiac ablation procedure or implantation of a pacemaker or defibrillator. As a researcher, I spend a good portion of my time looking at health disparities with the goal of improving access to high-quality health care for people of all races, genders and ages. I’ve been at Duke since 1999, when I started my residency. I decided to become a doctor because I had an interest in biology while I was in college. I chose cardiology because it is highly technical and gives me the chance to really get to know my patients over the course of treatment. Focusing on the heart also allows me to make a greater impact on health care, since heart disease is so common in the United States. Outside of work, I enjoy spending time with my family, including my two young children.

I am a cardiologist with a specialty in heart failure and transplant cardiology. I became a cardiologist because I enjoy interacting with and helping patients with complicated cardiac problems that require all of my clinical skills. It is really rewarding to see very sick challenging patients realize greater mobility and improved quality of life after working with them over months or even years. Here at Duke, we believe that developing strong personal relationships with our patients is fundamental to their success. I try to take a personal approach with each patient to encourage them to engage in a healthy lifestyle and to optimize their medical regimens to best suit their problems. A collaborative team of clinicians, nurses and staff work to achieve the best for our patients.

I chose to focus my research and practice on heart rhythm problems, because these problems, unlike many other heart conditions, can be cured. New treatment options for heart rhythm problems are rapidly evolving, which also makes this field very exciting. I have been at Duke for nearly 20 years. Both of my parents were involved in health care, so my choice of profession is part of a family tradition. I also went to a school where there was a strong tradition of community service, so I am thrilled that I get to wake up every day and get a chance to make a difference. As a heart rhythm specialist, I have the opportunity to make patients feel better right away without the use of many medications to help manage their condition, which I find extremely gratifying. I moved to North Carolina many years ago because of its natural beauty and still enjoy spending time outdoors as much as I can. I am a trained classical pianist and also play the cello.

I diagnose and treat cardiac arrhythmias, including atrial fibrillation, Wolff-Parkinson-White syndrome, supraventricular tachycardias (SVT), atrial flutter, and ventricular arrhythmias. I perform catheter ablation procedures, including minimally invasive catheter surgery, for these conditions. I also implant and manage devices, such as pacemakers, defibrillators, and cardiac resynchronization therapy (CRT) pacemakers or defibrillators. I also evaluate patients for possible genetic causes for sudden cardiac arrest or arrhythmias. Collaborating with a genetic counselor specializing in cardiac disorders, I perform genetic testing for these conditions. In addition, I evaluate athletes with cardiac conditions, focusing on arrhythmias and abnormal electrocardiograms. Dr. Daubert is rated as an Experienced provider by MediFind in the treatment of Postural Orthostatic Tachycardia Syndrome (POTS). His top areas of expertise are Atrial Fibrillation, Ventricular Tachycardia, Arrhythmias, Cardiac Ablation, and Pacemaker Implantation.

I fell in love with cardiology early in my medical training when I saw a patient in the emergency department who came in with a heart attack. The cardiology team swooped down and took him away to a procedure room, and in less than 45 minutes the heart attack had been stopped, and the patient was asking if he could go home. I'm so happy to be on that team now. I have extensive experience in minimally invasive procedures to treat people with a myriad of cardiac conditions. Most commonly, you can find me in the cardiac catheterization laboratory opening blockages in the arteries that feed the heart to treat angina or stop heart attacks. In the hospital, I also see patients with other acute cardiac conditions. In the office, I see patients with the entire range of heart problems. I'm excited to be joining Duke because I'll also be able to get back to doing research aimed at improving our understanding and management of patients with heart disease at the Duke Clinical Research Institute. In addition, I love to teach and learn, and there is no better place than Duke to stoke the intellectual curiosity that brought me to medicine in the first place.
