Name a common application for radiofrequency ablation.

Radiofrequency ablation is a medical procedure frequently utilized for the treatment of cardiac arrhythmias. This technique involves delivering radiofrequency energy to specific areas of the heart tissue responsible for abnormal electrical activity. The energy generates heat, which can destroy the faulty tissue while preserving the surrounding healthy tissues. As a result, this method can restore normal rhythm, improving the heart's function and alleviating symptoms associated with arrhythmias.

The other options, while relevant in their own contexts, do not pertain to the primary applications of radiofrequency ablation. For instance, treatment of respiratory infections generally relies on antibiotics or antiviral medications rather than ablation. Reduction of tumor size is typically achieved through methods like surgery, chemotherapy, or radiation, rather than solely depending on radiofrequency ablation, which is used mainly for specific tumors and conditions. Bone healing procedures involve different restorative techniques that do not employ radiofrequency ablation as a standard practice. Thus, the most accurate and common application of radiofrequency ablation among the options provided is the treatment of cardiac arrhythmias.
