MATHEMATICAL MODELLING OF MEDICAL-BIOLOGICAL PROCESSES AND SYSTEMS
Mathematical modeling of the efficiency of a defibrilling biphase rectangular signal of different duration
According to numerous studies, 76% of sudden cardiac arrest (SCA) are conditionally preventable, because occur due to ventricular fibrillation (VF) [1-3]. Immediate electrical impulse therapy (EIT) by external defibrillation is the main treatment for this type of arrhythmia [3-5]. Earlier, a comparative study of modern forms of impulses made it possible to reveal the concept of the development of this field of science . The analysis of the literature and the results of recent developments made it possible to determine the main parameters of the pulse for the individual selection of the characteristics of the transthoracic defibrillation signal. Representation of the average current (I) and charge (Q) in the form of a certain function I (t) is the optimal way to dose the defibrillation pulse .
