What is the purpose of ablation in cardiac treatment?

Ablation in cardiac treatment serves the specific purpose of partially destroying abnormal electrical conduction pathways within the heart. This procedure is commonly utilized to address arrhythmias, which are irregular heartbeats that can originate from these abnormal pathways. By selectively targeting and ablation the tissue responsible for these unwanted electrical signals, the treatment aims to restore a normal heart rhythm, thereby improving the patient's overall cardiac function and reducing the risk of complications associated with arrhythmias.

The other options do not align with the primary function of ablation. For instance, increasing heart rate, reducing blood pressure, and relieving chest pain are goals associated with different medical interventions and not directly related to the mechanism of ablation. The focus of this procedure is specifically on correcting the electrical activity of the heart, making the selected answer the most appropriate choice in this context.
