A medical device is provided, including an ablation system with a generator, at least one ablation element, a patient return electrode, and a feedback system to verify and monitor the electrical connection between the generator and the patient return electrode, as well as contact of the patient return electrode with the patient. The medical system sends a test signal to the patient return electrode prior to the delivery of ablation energy. If the response to the test signal indicates that the connection of the patient return electrode is absent, intermittent, or of low quality, the medical device may also provide notice, a warning or alarm.
