Cardiac Electrophysiology

An electrophysiologist is a heart doctor with a subspecialty focused on the electrical system of the heart. As an electrophysiologist, Dr. Meriwether treats patients who are experiencing a heart rhythm disorder or who are having symptoms causing their heart to beat in
an abnormal way.

“We are the electricians for the heart. We might find solutions with medication or devices, but there are also ablation procedures that can help many patients to never experience the arrhythmia again. We get ‘into the plumbing’ and get down to ‘the heart of the matter.’”
