A pacing system includes a controller operable to provide control signals indicating desired pacing signals, a pulse generator connected to the controller and operable to receive the control signals and to generate the desired pacing signals based on the control signals, at least one lead electrically connected to the pulse generator and extending into a user's heart and operable to provide the pacing signals to the heart, at least one electrode positioned in the user's heart and electrically connected to the at least one lead, the at least one electrode in contact with the user's heart and operable to stimulate the heart based on the pacing signals; and a transceiver, in communication with the pulse generator and operable to selectively transmit the pacing signals to the electrode wirelessly. The transceiver is controlled by the controller to transmit the pacing signals when pacing signals are not received by the electrode from the at least one lead. The lead may include multiple leads held together in a sugar moiety as a unitary body for insertion into the heart. Once in the heart, the sugar moiety dissolves to allow the leads to separate for implantation at different points in the heart.
