Occurring during or at the midpoint of shock
- The current in biphasic waveforms flows in a bidirectional pattern between the paddles (i.e., the direction of current flow reverses midshock as opposed to the unidirectional pattern seen with monophasic waveforms), resulting in a lower defibrillation threshold.2011, Bruno Bissonnette, Pediatric Anesthesia:
- [...] short-duration shock via two large electrodes or paddles coated with conducting jelly or a gel pad, positioned over the upper right sternal edge and the apex. Modern units deliver a biphasic shock, during which the shock polarity is reversed mid-shock.2013, Brian R. Walker, Nicki R Colledge, Stuart H. Ralston, Davidson's Principles and Practice of Medicine:
