1. A method for delivering ablation energy to tissue of a patient comprising: receiving or determining a measure of impedance between an electrode and the tissue of the patient; receiving or determining a measure of contact force between the electrode and the tissue; characterizing the tissue based on a ratio of the measure of impedance between the electrode and the tissue to the measure of contact force, wherein the ratio of the measure of impedance between the electrode and the tissue to the measure of contact force comprises a fraction in which a value of the measure of impedance is one of the numerator or the denominator and a value of the measure of contact force is the other of the numerator or denominator; causing the tissue characterization to be presented to a user, or applying the tissue characterization to calculate a metric and causing the metric to be presented to the user; and using the tissue characterization to control the delivery of the ablation energy to the tissue of the patient.
