The author analyzes in this book the electrical function of the heart, on the basis of the newest knowledge of electrophysiology. The metabolic function of heart muscle is reviewed. Several chapters are devoted to electrophysiological considerations. On the basis of calculation the dipole theory of the electrical field of the whole heart and single muscle fiber is rejected. Since construction of the heart vector is based on amplitudes which are modified by the electrical quality of the conducting tissue between heart and electrodes, the vector theory of the chest leads is also rejected. Instead, a new method is introduced, using two chest electrodes 3 cm. apart. Electrical fields between this bipolar electrode are measured in 1 and 0.5 cm. distances in horizontal and vertical directions and constructed in an "electrical picture of the heart." Normal and pathological heart pictures are analyzed by this method. Diffuse heart muscle changes are divided
