What is the primary purpose of tagging in 3D mapping during electrophysiology procedures?

• A. Annotates ablation sites and important anatomical/functional landmarks to guide subsequent lesions and documentation.
• B. Allows real-time hemodynamic monitoring.
• C. Provides a platform for telemedicine during the procedure.
• D. Replaces the need for fluoroscopy entirely.

Answer: (A)

Tagging in 3D mapping is about marking and labeling important points on the heart’s surface during the procedure. By placing visual markers at ablation sites and key anatomical or functional landmarks, you create a persistent map reference that guides where to deliver additional lesions and helps ensure the lesion set is complete. Tags can carry notes or attributes (such as what was ablated, energy delivered, or activation times), making it easier to reproduce the strategy, review the map later, and document the procedure accurately. This concept is not about real-time hemodynamic monitoring, telemedicine, or replacing fluoroscopy—those serve other roles in the lab. The tagging feature primarily provides precise, reproducible annotation of where ablation and critical landmarks occur to support effective therapy and documentation.
