In radiofrequency ablation, what is the purpose of impedance monitoring?

• A. To measure tissue type
• B. To control energy delivery and prevent overheating
• C. To assess patient comfort
• D. To track the procedure duration

Answer: (B)

In radiofrequency ablation, impedance monitoring plays a critical role in controlling energy delivery during the procedure. The primary purpose of this monitoring is to provide real-time feedback on the electrical resistance presented by the tissue being treated. As energy is delivered, the impedance readings help determine how much energy is being absorbed by the tissue. When tissue heats up, its impedance changes; monitoring these changes allows practitioners to adjust the power output to ensure that the tissue receives the correct amount of energy without overheating. Overheating can lead to unwanted thermal damage and complications, so maintaining appropriate impedance levels is essential for both the effectiveness of the ablation and the safety of the patient. This dynamic feedback loop aids in achieving a balance between effective treatment and minimizing risks associated with excessive heat. The ability to control energy delivery through impedance monitoring is why this answer is the most suitable choice regarding its purpose in radiofrequency ablation.
