Question

question 1 of 5
what is the rhythm? (select your answer)
no pulse
no pulse
normal sinus rhythm
pulseless electrical activity (pea)
idioventricular rhythm
asystole

Explanation:

• Normal Sinus Rhythm: Has a regular rhythm with consistent P - QRS - T complexes and a pulse. This is not the case here as there is no pulse.
• Pulseless Electrical Activity (PEA): Characterized by electrical activity (as seen in the QRS complexes) but no mechanical contraction (hence no pulse). The ECG shows intermittent QRS complexes but no pulse (as indicated by "NO PULSE" labels).
• Idioventricular Rhythm: Usually has wider QRS complexes (due to ventricular origin) and may have a slower rate. But the key here is the presence of electrical activity without a pulse which is more specific to PEA.
• Asystole: Shows a flat - line (no electrical activity). But this ECG has some electrical activity (QRS complexes).

Answer:

Pulseless Electrical Activity (PEA)
