Forging ahead: Update on radiofrequency ablation technology and techniques.

abstract：BACKGROUND:Contact-force (CF) sensing catheters are increasingly used in clinical electrophysiological practice due to their efficacy and safety profile. As data about the accuracy of this technology are scarce, we sought to quantify accuracy based on in vitro experiments. METHODS AND RESULTS:A custom-made force senso...
