Problem statement: The heart is the first organ and most importantly to form in the body, where is found the most powerful generator of electromagnetic energy in the human body. Electrophysiology is the best method used to diagnose human heart problem. Knowledge of the electrical potentials in human heart is a quantum leap in the science of the human heart. Recently, there has been a growing interest in studying the human ECG. However, is unfortunately a very complicated issue which requires a relatively good understanding of everything that has been said about the heart. Focus on the review of physical, electromagnetic basis of human heart's biopotentials and understanding the basic equations of cardiac electrophysiology that represents the basis to all clinicians whether in postnatal (pediatric or adult) or prenatal (foetal) Medicine. Approach: Mathematical method used for derivation of the essential equations of human heart electrical potentials, this equation will develop the principle sciences of human heart, the equation also outlier finding of the electromagnetic base of human electrophysiology. Results: Heart is important electrical generator in human body. The voltage and current which was generated in human heart represent the basis of heart biosciences. The electromagnetic energy of the heart not only envelops every cell of the human body, but also extends out in all directions in the space around human body. Conclusion: The proposed technique for electrophysiology and potentials on human ECG was useful and the results may contribute to the references for later studies.
