Multiple Choice

Pulseless electrical activity (PEA) is best defined as which?

Pulseless electrical activity is when the monitor shows organized electrical activity (an organized rhythm), but there is no palpable pulse or effective cardiac output. The crucial idea is the mismatch: the heart’s electrical system is firing, yet the heart isn’t producing mechanical activity to generate a pulse. This distinguishes it from asystole, where there is no electrical activity at all, and from a rhythm with a pulse, where both electrical activity and adequate heart output are present.
