The bi-phasic waveform in Biotronik devices uses a tilt of ______ / ______ %

• A. 60/50
• B. 50/60
• C. 70/30
• D. 60/40

Answer: (A)

Biphasic pulses are shaped by how the two phases are tilted, which controls how the energy is distributed between the phases and helps balance safety with effectiveness. In Biotronik devices, the standard biphasic tilt is 60/50, meaning the first phase is set with a 60% tilt and the second phase with 50%. This configuration provides efficient defibrillation with good charge balance and reduced residual DC or electrode polarization, across a variety of patient anatomies. Compared with the other tilts, 60/50 preserves a slightly greater emphasis on the first phase without making the second phase too weak or too unevenly matched, which could compromise efficacy or safety. A reversed tilt (50/60) changes the distribution and can be less optimal for energy delivery; a much more unbalanced tilt like 70/30 increases disparity and can raise tissue injury risk or reduce efficiency; a 60/40 tilt lowers the second phase energy and can affect charge balance and safety.
