Esophageal EPS can be used to assess the behavior of the AP, the inducibility of SVT, and the response to drug therapy. This procedure can be performed safely as an outpatient procedure requiring only sedation. Invasive EPS can also be performed for these risk-stratification indications, but this is usually reserved for patients undergoing radiofrequency (RF) ablation.
