摘要：
Systems and methods for assessing tissue contact, including positioning an electrode adjacent a tissue region delivering radiofrequency energy to the electrode, wherein the delivered radiofrequency energy is sufficient to ablate at least a portion of the tissue region obtaining a plurality of impedance measurements from the electrode during the delivery of the radiofrequency energy calculating a change in the impedance measurements over a pre-determined time period and generating an alert if the calculated change is less than a pre-defined value.
