Abstract:
An apparatus for applying biphasic myocardial stimulation, the apparatus comprising:at least two electrodes adapted to administer biphasic stimulation to myocardial tissue; and a pacemaker connected to provide biphasic stimulation to the at least two electrodes, wherein the biphasic stimulation comprises: a first stimulation phase having a first phase polarity, a first phase amplitude, a first phase shape, and a first phase duration, so as to precondition the myocardium to accept subsequent stimulation, and a second stimulation phase having a second phase polarity, a second phase amplitude that is larder in absolute value than the first phase amplitude, a second phase shape, and a second phase duration; and wherein the pacemaker repeatedly provides biphasic stimulation so long as fibrillation is detected.
