Abstract:
A patient monitoring system within an Electroconvulsive Therapy (ECT) device includes a patient monitoring channel including a first electrode and a second electrode, with each electrode coupled to a respective lead. The monitoring system also includes an Alternating Current source structured to inject a test current to the first electrode lead or the second electrode lead and a differential amplifier structured to measure differences between signals received from the first electrode lead and the second electrode lead. Related methods include evaluating a quality of an electrode contact with a skin surface by injecting a lead of the electrode and one input of a differential amplifier with a known electrical current, comparing a difference between an electrical signal received from the lead of the injected electrode as well as from a lead of a passive signal electrode, and evaluating the compared difference.
