What is the expected outcome of successful ablation of a focal arrhythmia?

Explanation:
Ablation is aimed at making a durable, lasting change in the heart tissue by destroying the small area that generates or conducts the abnormal rhythm. By delivering energy, the targeted cells are permanently damaged and replaced with scar tissue, which is non-conductive. This permanent tissue modification interrupts the arrhythmogenic pathway or focus, eliminating the arrhythmia in the long term. It’s not a temporary suppression, and increasing conduction velocity would not help; no effect would mean the problem remains. In successful cases, the arrhythmia is cured because the source of abnormal electrical activity has been permanently removed.
