"WebDec 16, 2016 · If DFT was greater than 600 V in the tuned waveform group, then the efficacy of 600 V shock was tested with SVC coil turned on. If DFT was greater than 600 V in the 50/50% tilt group, then the efficacy of 600 V shock was tested with a tuned waveform. If all shocks failed, the DFT is defined as 800 V (DFT—delivered energy as 36 J). " - Dft in cardiology
