Electrophysiology is a cardiac specialty that assesses the hearts electrical activity to diagnose arrhythmias, a disturbance of the heart’s normal rhythm.  

The main function of the heart is to pump blood to vital organs throughout the body but your heart does this through electrical pulses. Sometimes these pulses become out of sequence causing arrythmias. If left untreated or is poorly controlled, Arrhythmias can become more serious and even life threatening as patients are then at risk of a stroke or heart failure. 

Electrophysiologists have extensive experience in understanding the heart’s electrical system and detecting abnormal patterns in pulses. The Electrophysiologists at Northeast Georgia Medical Center (NGMC) will perform an EP study, using the most advanced technology to assess the nature of the abnormal heart rhythms and where it derives.  

What causes arrhythmias?

Electrical signals typically travel through the heart in a regular pattern but different factors including a heart attack, aging and high blood pressure can cause the heart to scar and beat in an irregular rhythm. Abnormal electrical pathways found with congenital heart defects can also cause Arrhythmias.

Patient Testimonial

“I had been struggling with atrial fibrillation for a long time. I experienced dizziness, fatigue and headaches… it’s nothing to play around with.

Dr. Sayar is just an amazing physician. He’s caring and personable, but also a very experienced and knowledgeable doctor – and Kristin Gilmore, RMA, along with his entire team is the same way. He not only saved my life, but the care he provided drastically improved my overall quality of life.”

Electrophysiology Services

Many of our electrophysiology services are performed in the cardiac catheterization labs at NGMC. We also see patients for ongoing outpatient care and consultations at The Heart Center of NGMC.

Electrophysiology Study

An EP study is a diagnostic test that involves mild sedation and a specialized electrode catheter, a thin tube that is gently inserted into the blood vessels leading to the heart. Once it is guided to the heart, your doctor will send small electric pulses through the catheters to prompt your heart to beat at different rates. The catheter’s electrodes collect data, called cardiac mapping, to evaluate the hearts electrical functions. During an EP study, an electrophysiologist may prompt arrhythmias and collect data about the events. The results of the study will help your doctor determine the necessary course of treatment.


Northeast Georgia Medical Center was the first hospital in Georgia to use cryoablation on adults, a technique to treat arrhythmias which involves freezing abnormal areas causing arrhythmias. In appropriate patients, cryoablation is often safer and easier to use than alternate procedures that treat by heating.

Implantable Cardioverter Defibrillator (ICD)

An ICD is a small, electronic device that is permanently place inside the body to help control the heart’s rhythm, speed and pattern. Like a pacemaker, it constantly monitors the heart rhythm. Most importantly, it has the ability to stop a dangerous arrhythmia.

Radiofrequency Catheter Ablation

In some situations, the specific area of the rhythm disturbance can be corrected by sending heat energy through a catheter to a small region of the heart to vaporize the abnormal area.


More than 2.7 million Americans have been diagnosed with atrial fibrillation, which is often called AFib. The condition occurs when the upper chambers of the heart—called the atria—beat irregularly, which disrupts blood flow in the heart. One of its side effects is an increased risk of stroke. Treatment has traditionally included lifelong blood-thinning medication therapy that carries side effects of its own, but a new device, called the WATCHMAN, offers an alternative.
