Electrical Impedance Tomography for monitoring cardiac radiofrequency ablation: a scoping review of an emerging technology

•The patient's CT scans and the catheter location mapping are beneficial to the Electrical Impedance Tomography.•The Electrical Impedance Tomography ablation signal can be expected to be a few to tens of mV.•Efficient solutions were found for treating almost noises except for the cardiac movement.•Electrical Impedance Tomography's promising results and improvements were found in Hyperthermia and other ablations.•In conclusion, Electrical Impedance Tomography is a promising solution for the lesion monitoring.
