Pacing systems for the heart employ multi-site contact points about desired
localized regions to deliver pacing train stimulation pulses to the
myocardium. The stimulation pulses can have an electric strength in the
range of about 5-10 times the diastolic pacing threshold. The electrodes
can be arranged as a single continuous body line electrode or as a
plurality of point electrodes and even as contiguous body electrodes
occupying increased portions of the myocardium over conventional pacing
electrodes. Configuring the electrodes in spaced apart operational pairs
(with simultaneous excitation) may capture increased areas of the
myocardium. The pacing stimulation may be used as an alternative to
conventional defibrillation treatments (shocks) or to reduce the strength
of the defibrillation shock pulse.
