Area Under the Real-Time Contact Force Curve (Force-Time Integral) Predicts Radiofrequency Lesion Size in an In Vitro Contractile Model

FTI Predicts RF Lesion Size in Contractile Model. Introduction: Electrode tissue contact, radiofrequency (RF) power and duration are major determinants of RF lesion size. Since contact forces (CF) vary in the beating heart, we evaluated contact force–time integral (FTI) as a predictor of lesion size...
