Electrophysiology is the branch of cardiology that specializes in the diagnosis and treatment of abnormal heart rhythms. Although it is the fastest-growing cardiology field, electrophysiology specialists are not typically found in smaller communities. The first in Northwest Arkansas were Boris Bogomilov, MD and Soliman A. Soliman, MD, at Washington Regional’s Walker Heart Institute. They work closely with other cardiologists to evaluate and treat patients with heart rhythm disorders.


Your physician may order an electrophysiology study, or EP study, to help identify what is causing your heart rhythm problem, or arrhythmia.

Treatment Options

Electrophysiologists are often able to use special implantable devices, such as defibrillators and pacemakers, including Micra™, to treat a patient’s arrhythmia. These devices are essentially tiny computers that are programmed to treat the patient’s specific condition. They are monitored remotely by the electrophysiology staff, oftentimes allowing them to see if a patient is developing a problem before the patient feels anything or reports any symptoms. Addressing those problems at such an early stage can lower the risk of complications and reduces unnecessary hospitalizations.

Cardiac ablation may also be used to treat arrhythmia. This minimally invasive procedure uses radiofrequency energy to create tiny scars in heart tissue to block electrical signals that are causing the abnormal heart rhythm.

For patients with atrial fibrillation, or A-fib, electrophysiologists may implant a device called WATCHMAN. Atrial fibrillation is an irregular heartbeat that can lead to blood clots and possibly stroke. The WATCHMAN implant closes off a small portion of the heart to keep blood clots from forming.
