Apparatus (18) for applying a signal to a heart (20) of a human subject is provided. The apparatus includes a set of one or more electrodes (98), adapted to be coupled to the right ventricular septum of the heart. A control unit (90) of the apparatus is adapted to drive the electrode set to apply an Excitable-Tissue Control (ETC) signal to the septum (22). Preferably, the control unit is adapted to configure the signal to be capable of modifying contractility of a portion of the heart. |
