A method and an apparatus for the treatment of cardiac arrhythmias using a weak pulsed magnetic field. A transducer that emits electromagnetic radiation of a prescribed frequency and peak intensity is placed on the patient's chest and, as a result, the weak electromagnetic field can cause activation, reactivation, inhibition or remodeling of electrophysiological change in cardiac tissue in an irradiated heart. This treatment method has wide application for use in patients who experience cardiac arrhythmia.
