Popis:	A comparative study of the energy efficiency of three known versions of chopping-modulated defibrillation pulses was carried out using the hypothesis of guaranteed defibrillation and the ten Tusscher−Panfilov 2006 cardiomyocyte model subjected to simulated fibrillation. The results of the study showed that the unmodulated equivalent of a chopping-modulated defibrillation pulse has lower threshold energy of guaranteed defibrillation than the chopping-modulated pulse itself. In addition, the ratio of the threshold energy of guaranteed defibrillation of the chopping-modulated pulse to the threshold energy of its unmodulated equivalent is approximately equal to the reciprocal of the modulation duty cycle. Based on this, it can be assumed that the use of chopping modulation for defibrillation pulse shaping leads to a decrease in its energy efficiency.
