Abstract

An implantable electrode lead for tissue stimulation adapted to be attached to an implantable tissue stimulator provided with a pulse generator, has at least two stimulation electrodes to apply stimulation pulses to said tissue and arranged close to the distal end of the electrode lead, and at least two electrical conductors to connect said electrodes to said pulse generator. The electrode lead further has a switching unit arranged close to the distal end of the electrode lead and adapted to switch the electrode lead between a local pacing mode and a normal pacing mode, the switching unit being controlled by a mode control signal. Further, a pacing module is arranged close to the distal end of the electrode lead and in relation to the switching unit and being connectable to said at least two stimulation electrodes, the pacing module includes a pulse generating unit to generate stimulating pulses to be applied to the tissue by the stimulation electrodes. When the electrode lead is in the local pacing mode the electrical conductors are disconnected from said stimulation electrodes which instead are connected to the pacing module, and when the electrode lead is in the normal pacing mo…
