Final answer:
During a slow pathway ablation, the ablation catheter should be positioned above the CS catheter in RAO for accuracy and safety.
Step-by-step explanation:
In a slow pathway ablation procedure, the ablation catheter should always be above the CS catheter in RAO.
The ablation catheter is placed in the heart to destroy abnormal electrical pathways that cause arrhythmias. RAO (right anterior oblique) is an imaging view that helps guide the ablation procedure.
By positioning the ablation catheter above the CS catheter in RAO, it ensures that the procedure is performed accurately and safely.
