Electrophysiology
Get your heart rhythm back to normal with help from an electrophysiologist at OSF HealthCare Cardiovascular Institute and its network of clinics. This type of cardiologist (heart doctor) focuses on the electrical signals that cause arrhythmia — irregular heartbeats. Whether you need monitoring, medication or a procedure, count on us for expert care.
Where can I see an electrophysiologist?
Your primary care doctor can refer you to an OSF Cardiovascular Institute specialist in electrophysiology near you in:
- Bloomington, Illinois
- Escanaba, Michigan
- Galesburg, Illinois
- Ottawa, Illinois
- Peoria, Illinois
- Rockford, Illinois
- Urbana, Illinois
Heart Arrhythmia Tests and Diagnosis
If you have symptoms of an irregular heartbeat, your doctor may recommend an electrocardiogram (EKG), Holter monitor or event monitor. Each type of technology places sensors on your chest to track your heart rate over different periods of time — from a few minutes to several weeks. It’s simple, painless and noninvasive. That means you get insight into your heart health as easily as possible.
Electrophysiology (EP) Study
Your care team may need more information than a noninvasive test can provide. In that case, your doctor may order an EP study. During this procedure, your doctor inserts a thin tube with an electrode into a blood vessel and moves it up to your heart to map its electrical signals. It shows the reason for irregular heartbeats. Your doctor can use the information to guide ablation — treatment to stop arrhythmias.
Arrhythmia Treatment
If you need a procedure to restore a healthy heartbeat, it may take place in a special area of the hospital called an electrophysiology (EP) lab. Most procedures are less invasive than surgery, which means they’re safer and reduce your recovery time.
