Answer

AHA recommendations for defibrillation include the following [60] :

  • Use defibrillators (using biphasic truncated exponential [BTE], rectilinear biphasic [RLB], or monophasic waveforms) to treat atrial and ventricular arrhythmias. (Class I)
  • Defibrillators using biphasic waveforms (BTE or RLB) are preferred. (Class IIa)
  • Use a single-shock strategy (as opposed to stacked shocks) for defibrillation. (Class IIa)
  • The benefit is unclear for using a multimodal defibrillator in manual instead of automatic mode. (Class IIb)
  • The value is unclear regarding VF waveform analysis to guide management of defibrillation. (Class IIb)

Overall, the ERC and ILCOR guidelines concur with those of the AHA, [61, 62]  but the ERC includes an additional recommendation for self-adhesive defibrillation pads which are preferred over manual paddles and should always be used when they are available. [62]
