رجل عمره ٦٣ سنة في وحدة القلب بعد احتشاء أمس، كان يتكلم مع زوجته. فجأة ظهر على الشاشة خط متموج غير منتظم بدون مركبات QRS، وانطلق الإنذار. ما أول إجراء؟

A 63-year-old man in the coronary unit after yesterday’s MI was talking to his wife. Suddenly the monitor shows an irregular wavy line with no QRS complexes and the alarm sounds. What is the first action?

1. Check the client’s responsiveness and pulse
2. Give adrenaline 1 mg IV
3. Check the leads and electrodes first, then the client
4. Prepare an unsynchronised shock without checking the client

Answer: A) Check the client’s responsiveness and pulse. A VF-like trace may be real or artefact from movement or a loose lead. The first step is the client: responsive with a pulse? If not, start CPR and defibrillate at once.
