متن کاملContact Force and Atrial Fibrillation Ablation.
Catheters able to measure the force and vector of contact between the catheter tip and myocardium are now available. Pre-clinical work has established that the degree of contact between the radiofrequency ablation catheter and myocardium correlates with the size of the delivered lesion. Excess contact is associated with steam pops and perforation. Catheter contact varies within the left atrium ...
متن کاملContact Force in Atrial Fibrillation: Role of Atrial Rhythm and Ventricular Contractions: Co-Force Atrial Fibrillation Study.
BACKGROUND In an experimental model, variable and intermittent contact force (CF) resulted in a significant decrease in lesion volume. In humans, variability of CF during pulmonary vein isolation has not been characterized. METHODS AND RESULTS In 20 consecutive patients undergoing CF-guided circumferential pulmonary vein isolation, 914 radiofrequency applications (530 in sinus rhythm and 384 ...
متن کاملDesign and Construction of a Novel Tactile Sensor for Measuring Contact-Force, Based on Piezoelectric Effect
In this paper, design and construction of a tactile sensor for measuring contact-force is presented. Mechanism of measuring contact-force in this tactile sensor is based on impedance changing of piezoelectric crystal and voltage of different points in circuit as a result of applying force on the crystal. By considering a specific point in the circuit and recording the changes of its voltage, ma...
متن کاملContact force technology in catheter ablation of atrial fibrillation
Catheter ablation of atrial fibrillation (AF) has an indisputable value in the treatment of patients with symptomatic drug refractory AF. Nowadays, special interest is paid to improve the efficacy and the safety of the procedure and new approaches allowing better understanding of the lesions creation and its control have been developed. A lot of factors including power and duration of energy de...
