Patients with a pacemaker or ICD: care after implant, wound and arm care, device teaching
- Safe practice
After a pacemaker or defibrillator implant, the nurse watches the rhythm and wound, limits the arm on that side, and teaches device safety and when to call.
What it is
A pacemaker treats a heart that beats too slowly; an implantable cardioverter-defibrillator (ICD) detects a dangerous fast rhythm and delivers a shock to stop it. After the implant the nurse watches the monitor, the wound and the vital signs, and helps the patient keep the arm on the device side low and still so the leads stay in place. Teaching covers wound care, arm and lifting limits for the first weeks, carrying the device card, keeping magnets and some equipment away from the device, check-ups, and what to do after an ICD shock.
What it requires
- Rhythm monitoring after the implant and comparison with the expected device function.
- Wound care and early detection of bleeding, haematoma or infection.
- Protecting the leads: arm and lifting limits for the first weeks.
- Device teaching: card, magnets and equipment, phones, security checks, imaging tests and check-ups.
- Planning with the team what to do after an ICD shock.
How it is applied (and why)
- Attach the cardiac monitor and watch the rhythm and heart rate as ordered — shows whether the device is working as expected.
- Measure vital signs and ask about dizziness, chest pain and breathlessness — these may mean a device or lead problem.
- Inspect the dressing and the pocket for bleeding, swelling or a haematoma — the pocket can bleed in the first hours.
- Help the patient keep the device-side arm low and avoid raising it above the shoulder — a new lead can move.
- Report persistent hiccups — they are one of the warning signs after a device implant.
- Teach wound care: keep it dry as instructed, hand hygiene, no creams, and the infection signs — the pocket can become infected.
- Teach the device card, magnets and equipment distances, phone side and security checks — strong fields can interfere.
- For an ICD, agree with the team on what to do after a shock and teach it to the family — the plan avoids panic.
- Confirm the check-up dates and that every provider is told about the device before tests — some tests need settings checked.
In nursing practice
- Call for wound redness, swelling, more drainage, pain or fever.
- Call for dizziness, fainting, breathlessness, chest pain or a return of the symptoms the device was meant to treat.
- Call for persistent hiccups or a pulse well below the expected rate.
- After an ICD shock: report it; if the patient feels unwell, faints or receives several shocks, use the emergency plan agreed with the team.
- Tell every provider about the device before tests; ask the cardiologist before an MRI.
Common mistakes
- Lifting the device-side arm above the shoulder to dress the patient in the first weeks.
- Not reporting persistent hiccups.
- Forgetting to give the device card and its explanation at discharge.
- Leaving the patient without a plan for what to do after an ICD shock.
- Not telling the imaging or surgical team that the patient has a device.
Test yourself
Think of the answer, then tap the question to see it.
Why is the arm on the device side kept below the shoulder in the first weeks?
To keep the new leads from moving out of place while they become fixed in the heart.
Which symptoms after a pacemaker or ICD implant should be reported?
Wound redness, swelling, drainage or pain, dizziness, fainting, chest pain, breathlessness, persistent hiccups or the return of the old symptoms.
What should a person with an ICD do after a shock?
Report every shock to the cardiology team; if they feel unwell, faint or get several shocks, follow the emergency plan agreed in advance.
Which device precautions are taught at discharge?
Carry the device card, keep magnets and some power tools away, use the phone on the opposite side and show the card at security checks.
