Abstract:
A cardioversion arrangement comprising:an electrode arrangement for the endocardial discharge of electrical pulses in an atrium or a ventricle of a heart, said electrode arrangement having an electrode line with a distal end and a plurality of electrodes disposed in the region of the distal end, which can be electrically connected by way of the electrode line to an electrical pulse-discharging device wherein the distal end of the electrode line is split into two branches and the plurality of electrodes are split between the two branches, one of the two branches is in the form of a septal branch and the other is in the form of a lateral branch for respectively assuming a septal position and a lateral position in the atrium or the ventricle of the heart; and control means for actuating an electrode from the septal branch and a respective electrode of the lateral branch such that each electrode of a branch is associated in a pair-wise manner with an electrode of the other branch and is actuated one of simultaneously and in a cascade fashion with its respective, paired electrode for bipolar discharge of stimulation electrical pulses, wherein the cardioversion arrangement is designed to record intra-atrial electrograms by receiving electrical signals between the paired electrodes of the plurality of electrodes in the bipolar mode of operation.
