Abstract
Methods and systems for switching electrode configurations for measuring the transthoracic impedance of patient are described. Various embodiments provide stimulation devices and methods that can automatically adapt to different minute ventilation electrode configurations. This, in turn, permits minute ventilation functionality to continue, e.g. rate-responsive pacing, in spite of the fact that an electrode configuration has changed. Accordingly, minute ventilation functionality can automatically continue in a adaptive manner when a previously-available electrode configuration is no longer available for minute ventilation functionality.
