What is the primary goal of cardiac ablation?

• A. Permanently damage cells of arrhythmogenic focus
• B. Temporarily suppress arrhythmias
• C. Remove tissue
• D. Alter heart rate

Answer: (A)

The main concept here is that the goal of cardiac ablation is to permanently eliminate the tissue that generates or sustains the abnormal rhythm. By delivering energy to the arrhythmogenic focus or pathway, ablation creates durable scar that interrupts the electrical circuits responsible for the tachycardia, aiming for lasting cure rather than a temporary fix. While there may be immediate, short‑term changes such as edema causing temporary slowing, the success of ablation lies in creating permanent lesions that prevent recurrence. It’s not about physically removing tissue or directly changing the heart rate; those descriptions don’t capture the intended lasting disruption of the aberrant electrical conduction.
