Which management step is not appropriate for true asystole?

In true asystole there is no electrical activity in the heart, so shocking the chest is not helpful. The best approach is to maximize perfusion and monitor for any change in rhythm. Start high-quality chest compressions immediately to maintain blood flow, and give epinephrine to improve coronary and cerebral perfusion pressures. Periodic rhythm checks are performed to detect any progression to a shockable rhythm, but these checks are brief and spaced within CPR cycles so they don’t unduly interrupt chest compressions. Immediate defibrillation is not appropriate because there is no beat to halt or reset with a shock in true asystole. The other steps are consistent with managing asystole: maintaining effective CPR, administering vasopressor support, and monitoring for a rhythm change that could indicate a shockable rhythm. Continuous rhythm checks would disrupt ongoing CPR, which is why rhythm assessment is done at intervals rather than continuously.
