Abstract
Following an administered shock in cardiac arrest, the heart commonly experiences a short phase of inability to efficiently perfuse. Despite being a commonly used feature in the ICD population, postshock pacing (PSP) is yet to be adequately explored for its utility in this pulseless phase. Notably, an overwhelming proportion of available data for transcutaneous pacing in spontaneous cardiac arrest stem from the 1980s and 1990s and revolve largely around nonshockable, as opposed to shockable rhythms. The lack of large-scale clinical trials assessing the efficacy of transcutaneous PSP and the considerable advancements in technology and training facilities since the 1990s indicates a need for reevaluation of current understanding of PSP and its applicability in cardiac arrest. Shedding light into the possible implications of transcutaneous PSP in emergency setting cardiac arrest may not only reshape the current protocols of ALS but also carry the potential of improving survival rates. This concise review serves as a summary of the existing knowledge on the subject of PSP and reveals further possible directions for the development of this therapy.
