<p>An apparatus comprising leads adapted to apply electrical stimulation to a cardiac blood pool and stimulation generator connected to the leads, wherein the stimulation generator produces a biphasic electrical waveform to stimulate the cardiac blood pool via the leads to effect cardiac pacing. The electrical waveform comprising a first stimulation phase with a first phase polarity, a first phase amplitude (104, 204, 304, 406, 504), a first phase shape and first phase duration (106, 206, 306, 404) and a second stimulation phase with a second phase polarity, a second phase amplitude (104, 204, 304, 406, 504), a second phase shape and second phase duration (106, 206, 306, 404), wherein the first phase polarity is positive.</p> |
