مريض في برنامج التأهيل القلبي بعد احتشاء. نبضه أثناء الراحة ٧٢. بعد المشي في الممر صار نبضه ٩٨ وضغطه نزل من ١٣٠/٨٠ إلى ١١٦/٧٤. ما التصرف الصحيح؟

A client in post-MI cardiac rehab has a resting HR of 72. After walking in the corridor his HR is 98 and BP has fallen from 130/80 to 116/74. What is the correct action?

1. Give nitroglycerin and resume walking after 5 minutes
2. Stop the activity, rest the client and reassess
3. Encourage him to finish the walk because this response is normal
4. Increase the distance next session because he tolerates effort

Answer: B) Stop the activity, rest the client and reassess. Signs of activity intolerance after MI include a heart-rate rise of more than 20 above resting and a fall in systolic pressure with exertion. Here the rise is 26 with a falling BP, so the activity stops and he is reassessed.
