contact force sensing
Technology in ablation catheters that measures the perpendicular force applied against cardiac tissue during energy delivery.
Full Definition
Contact force sensing is a catheter technology that provides real-time measurement of the perpendicular force applied between the ablation catheter tip and cardiac tissue. This technology helps optimize lesion creation by ensuring adequate tissue contact (typically 5-40 grams) while avoiding excessive force that could cause perforation. Contact force data correlates with lesion depth and permanence, making it crucial for successful ablation outcomes and procedural safety.
Usage
Usage note: Often abbreviated as CF in procedural notes. Essential for modern ablation safety protocols.
