The aim of the study was to compare DT in two different biphasic waveforms on high impedance porcine model. Methods: In 18 anesthetized pigs (33–60 kg) we evaluated energy of the TD (ETD) that would terminate electrically induced 20 sec VF. The quasi-sinusoidal pulse (BQS) has the amplitude of 2nd phase ∼50% from 1st one and durations 5.6 and 4.4 ms respectively. The BQS pulse was delivered by MSIEE experimental defibrillator and biphasic rectilinear pulses (BRL) – defibrillator ZOLL E Series. These defibrillators compensate high impedance by controlling current with fixed pulse duration (10 ms). The pulses shape corresponded to load resistance 100 ohms regardless of pig chest impedance (43–77 ohms). Results: ETD of BRL pulse in 11 from 18 pigs was 16 (8–26)% more, than BQS pulse, in 3 pigs 12 (9–13)% less than BQS pulse p
