Abstract: The exemplary systems and methods may be configured to monitor electrical activity from a patient using a plurality of external electrodes. The exemplary systems and methods may be further configured to provide a model heart representative of the patient's heart based on at least one of a plurality of patient characteristics. The model heart can include a plurality of segments. The exemplary systems and methods may be further configured to determine a value of electrical activity for each of a plurality of anatomic regions of the model heart based on the mapped electrical activity. Each of the plurality of anatomic regions can include a subset of the plurality of segments.

Abstract: A device and method are described for transmitting tissue conductance communication (TCC) signals. A device may be is configured to establish a transmission window by transmitting a TCC test signal at multiple time points over a transmission test period to a receiving device and detect at least one response to the transmitted TCC test signals performed by the receiving device. The IMD is configured to establish the transmission window based on the at least one detected response so that the transmission window is correlated to a time of relative increased transimpedance between a transmitting electrode vector and receiving electrode vector during the transmission test period.
