The paper discusses how to choose the optimum shape of a pulse for electric defibrillation of the heart. The authors' data are given on the values of an induced field in the contracting myocardial structure when a defibrillator evokes pulses. Mono- and bipolar pulse-induced changes of the transmembranous potential on the hyper- and depolarized sides of a cell are calculated. Mechanisms of defibrillation in the use of pulses of different shapes are considered.
