Prediction and assessment of ablation of cardiac tissue

[Subject] Method for carrying out ablation of the organization in the fixed organ in a fixed subject's inside of the body. [Solution means] The above-mentioned method includes the processing which uses the above-mentioned probe and measures one or more local parameters in the above-mentioned position, before carrying out ablation of the processing which introduces a fixed probe into the inside of the body fixed to the fixed position in contact with the organization which does ablation, and the above-mentioned organization. The map of a fixed organ is displayed and the grade of the fixed ablation of the organization attained corresponding to the energy of the fixed dosage supplied in the above-mentioned position using the above-mentioned probe predicted is shown based on the one or more above-mentioned local parameters. It is supplied in order that the energy of this fixed dosage may carry out ablation of the above-mentioned organization using the above-mentioned probe, and the grade of the actual fixed ablation in the above-mentioned position is measured by the above-mentioned probe following the ablation of the above-mentioned organization. The grade of this measured actual ablation is displayed on the above-mentioned map, in order to compare to the predicted above-mentioned grade. [Selection figure] Fig. 1
