PROBLEM TO BE SOLVED: To provide a biphasic electrical cardiac pacing. SOLUTION: An apparatus for muscular stimulation contains means for defining a first stimulation phase with a first phase polarity, a first phase amplitude, a first phase shape and a first phase duration for pre-conditioning myocardium to accept subsequent stimulation, means for defining a second stimulation phase with a polarity opposite to the first phase polarity, a second phase amplitude that is larger in absolute value than the first phase amplitude and a second phase duration and means for applying the first stimulation phase and the second stimulation phase in sequence to a cardiac tissue. The two phase stimulation is applied sequentially. Anodal stimulation is first applied and followed by cathodal stimulation.
