Electrophysiology Study (EPS)
An EPS uses fine catheters to record the heart's electrical signals from the inside, mapping exactly where an abnormal rhythm begins — often uncovering problems a surface ECG cannot catch, and guiding the right treatment.
When you might need it
- Unexplained palpitations or a racing heart
- Fainting or blackout spells
- Dizziness with a suspected rhythm problem
- Before a planned ablation
- Finds the source
- Guides treatment
- Low-risk day procedure
