Summary:Systems and methods for monitoring return patch impedances are provided. A tissue therapy system includes a catheter comprising at least one electrode, the catheter implantable in a patient, a first return patch electrode configured to be applied to skin of the patient, a second return patch electrode configured to be applied to the skin of the patient, and an impedance measuring circuit lectrically coupled to the at least one catheter electrode, the first return patch electrode, and the second return patch electrode. The impedance measuring circuit is configured to drive currents between the at least one catheter electrode, the first return patch electrode, and the second return patch electrode, detect, using a voltage at the at least one catheter electrode as a reference voltage, voltages generated in response to the driven currents, and measure impedances based on the driven currents and the detected voltages.
