EPS and RFA

1. What are EPS and RFA?
An Electrophysiology Study (EPS) evaluates the heart's electrical activity and identifies the source and mechanism of an abnormal heart rhythm. Radiofrequency Ablation (RFA) can then be used to treat the identified abnormal electrical pathway.

2. When are EPS and RFA recommended?
They may be recommended for symptomatic or recurrent arrhythmias such as supraventricular tachycardia (SVT), atrial flutter, selected cases of atrial fibrillation, and certain ventricular arrhythmias.

3. How is an EPS performed?
Thin electrical catheters are introduced through a blood vessel, usually in the groin, and advanced into the heart. The catheters record electrical signals and can stimulate the heart to identify the abnormal rhythm pathway.

4. How is Radiofrequency Ablation performed?
Once the responsible area is identified, the electrophysiologist positions an ablation catheter at the target site and delivers radiofrequency energy to create a small controlled area of scar tissue that interrupts the abnormal electrical pathway.

5. What technology is used during RFA?
Modern procedures may use three-dimensional electroanatomical mapping, intracardiac imaging, and specialized mapping catheters to improve localization and treatment accuracy, particularly for complex arrhythmias.

6. How long does EPS and RFA take?
The duration varies according to the type and complexity of the arrhythmia. Some procedures may take a few hours, while complex ablations can take considerably longer.

7. What is recovery like?
Patients are usually monitored for several hours after the procedure, particularly for bleeding at the catheter insertion site. Many uncomplicated cases allow discharge the same day or after an overnight stay, depending on the procedure and clinical condition.

8. What are the possible risks?
Potential complications include bleeding or bruising at the catheter site, blood-vessel injury, infection, abnormal heart rhythms, blood clots, and, depending on the location and type of ablation, damage to nearby cardiac structures or the normal electrical conduction system.

9. Why consider India for EPS and RFA?
India has experienced cardiac electrophysiologists, advanced electrophysiology laboratories, three-dimensional mapping systems, modern ablation technologies, and multidisciplinary cardiac-care facilities at comparatively affordable costs.

10. How can Medavelle help?
Medavelle can coordinate evaluation with an experienced cardiac electrophysiologist, arrange review of ECG, Holter, echocardiography, and other cardiac records, obtain a personalized treatment estimate, and assist with hospital, travel, and treatment coordination in India.
