Abstract
The disclosed technology includes a system for applying pulsed field ablation to treat atrial fibrillation. The system includes a catheter and a processor. The catheter can include a tip electrode controlled to emit either a pulsed electric field or a radiofrequency signal to biological tissue and ablate one or more locations of biological tissue of the pulmonary vein. The processor is configured to measure a contact force experienced by the tip electrode against biological tissue during pulsed electric field ablation and determine a pulsed field ablation index as a function of the measured contact force and number of pulsed electric field applications for each location of the one or more locations so that it can be determined whether a lesion is sufficiently durable.
