A non-shockable rhythm is a cardiac arrest rhythm that will not respond to defibrillation because there is no organized electrical activity for a shock to reset. The two non-shockable rhythms are asystole (a flatline, with no electrical activity) and pulseless electrical activity (PEA), in which electrical signals are present but produce no effective pulse.
Because a shock offers no benefit, treatment centers on uninterrupted high-quality CPR, administration of epinephrine, and a focused search for and correction of reversible causes (the Hs and Ts). Distinguishing non-shockable from shockable rhythms quickly and accurately is a fundamental skill, since it determines the entire treatment pathway during resuscitation.
