Abstract:
A heart stimulator comprising: a stimulation energy delivering assembly including at least one lead, adapted for implantation in contact with cardiac tissue, for delivering stimulation energy via said lead, an atrial arrhythmia detector, and a control unit connected to said detector and to said stimulation energy delivering assembly for controlling said stimulation energy delivering assembly to deliver at least one primary atrial arrhythmia abolishing stimulus via said lead and after a predetermined time, if continued atrial arrhythmia is detected by said detector, antithrombus stimulation energy in a form selected from the group consisting of pulses and burst of pulses of different timing and energy levels from the primary stimulus for producing an atrial contraction that promotes hemodynamic blood transportation away from the atrium and prevents thrombi formation in the atrium.
