What should patients with a pacemaker avoid for the first 6-8 weeks?

• A. Lifting the arm with the pacemaker leads above the head
• B. Running marathons
• C. Eating dairy products
• D. Taking antibiotics

Answer: (A)

The key issue is healing of the device pocket and securing the leads. After implantation, the leads and the pocket need time to settle, so movements that stretch the healing area should be avoided. Lifting the arm on the side with the pacemaker and raising it above the head can pull on the leads or disrupt the pocket, increasing the risk of lead displacement or hematoma. That’s why avoiding overhead arm movements for about 6–8 weeks is advised.

Other activities like running or daily food or medication choices don’t directly affect the healing of the pacemaker leads, and thus aren’t the specific restriction in this early period. Over time, activity can usually be gradually increased under clinician guidance.
