Radiofrequency ablation (RFA) is a procedure used to treat some types of heart arrhythmias. What happens during an EP study or RFA? An EP study usually takes 1 to 2 hours.
What are EP and RFA, and why are they used?
An electrophysiology (EP)
study is a test that shows how electrical signals move in pathways through your heart. When the pathway is normal, your heartbeat is regular. When these signals are abnormal, your heartbeat is irregular. An irregular heartbeat is called an arrhythmia Symptoms of an arrhythmia are different in each person. They can include:
- A pounding or rapid heartbeat
- A heart “flutter”
- Dizziness or feeling lightheaded
- Shortness of breath
Radiofrequency ablation (RFA) is a procedure used to treat some types of arrhythmias. In most cases, it can be done at the same time as an EP study. Your doctor will tell you if you are scheduled for an EP study, an RFA procedure, or both.
What is electrophysiology study with ablation?
An electrophysiology study is a test to measure the electrical activity of the heart and to diagnose arrhythmia or abnormal heart rhythms. Catheter ablation is a procedure performed to treat some types of arrhythmia.
How is an electrophysiology study performed?
An electrophysiology (EP) study is a test performed to assess your heart’s electrical system or activity and is used to diagnose abnormal heartbeats or arrhythmia. The test is performed by inserting catheters and then wire electrodes, which measure electrical activity, through blood vessels that enter the heart.
Is EP study painful?
An EP study doesn’t hurt, but you may feel uncomfortable as your heartbeat is sped up or slowed down. Tell your care team if you feel any pain.
Where is the catheter inserted for cardiac ablation?
During cardiac ablation, catheters are passed through a vein in order to reach your heart. Catheters may be inserted in your groin, your shoulder or your neck.
