رجل عمره ٥٨ سنة عنده جهاز صدمات مزروع (ICD) بعد توقف قلب سابق. اتصل من البيت: أعطاه الجهاز صدمة واحدة قبل ١٠ دقائق وهو جالس، والآن يشعر أنه بخير تماماً بدون ألم صدر أو دوخة أو ضيق نفس. ما النصيحة الأنسب؟

A 58-year-old man with an implanted cardioverter-defibrillator after previous cardiac arrest calls from home: the device gave one shock 10 minutes ago while he was sitting, and he now feels completely well, with no chest pain, dizziness or breathlessness. What is the best advice?

1. No need to tell anyone because the device is working
2. Tell the device clinic today; call an ambulance if shocks recur
3. Stop rhythm medicines until the clinic visit
4. Go to the ED by ambulance immediately in every case, even when feeling well

Answer: B) Tell the device clinic today; call an ambulance if shocks recur. A single shock followed by feeling well needs a call to the device clinic so the data can be reviewed. Repeated shocks, or a shock with chest pain, syncope or dyspnoea, need emergency care.
