This diagnostic procedure provided a considerable amount of information about your heart rhythm. Sometimes during the EPS, it becomes clear to the doctors that radiofrequency ablation is the treatment of choice. Then, if necessary, the treatment procedure can be performed right away, without requiring you to schedule another visit to the hospital. It does involve some risk. Rare complications include damage to the heart and blood vessels, formation of blood clots, stroke, heart attack and infection.
Deaths are very rare.
Before the ablation, a heart doctor will examine you and review your medical history and diagnostic tests. He will explain the procedure and its risks and benefits. Do not hesitate to ask questions and voice your concerns. Tell the doctor if you are pregnant or if you have allergies, especially if you have allergies to any medications. Usually, you will have blood tests, an electrocardiogram, and a chest x-ray taken prior to the procedure.
