High Power Short Duration Radiofrequency Ablation of Atrial Fibrillation Using the QDOT MICRO™ Catheter

Compared to conventional radiofrequency (RF) ablation, which is performed with a power set of 30-40 Watt for a duration of 20-30 seconds, ablation with higher power and shorter duration (vHPSD, 90W/4sec) may result in more continuous and more durable ablation lesions with a similar safety profile, while reducing procedure duration.
