## Direct answer
A pacemaker is an implanted electronic device that delivers electrical impulses to the heart muscle when the intrinsic rhythm fails, used for symptomatic bradycardia, complete heart block, sick sinus syndrome and certain tachyarrhythmias. Nursing care after implantation focuses on wound care, preventing lead displacement, monitoring the paced pulse, and teaching lifelong safety around electromagnetic fields. The patient leaves with a device identity card and the habit of counting their own pulse every day — a fall below the programmed lower rate is the key warning sign to report.

## What you must remember
- Common indications: symptomatic third-degree AV block, Mobitz II block, sick sinus syndrome and symptomatic bradycardia; temporary pacing supports patients awaiting permanent implantation.
- Basic modes: VVI (ventricular pacing, single lead) for atrial fibrillation with slow ventricular rate; DDD (dual chamber, sequential atrio-ventricular pacing) mimics physiological conduction.
- Pulse generator is implanted subcutaneously below the clavicle with leads through a vein; battery life commonly ranges from 6 to 10 years depending on pacing dependence.
- Immediate post-op care: monitor ECG and vital signs, check the incision for bleeding, haematoma and infection, and keep the arm on the operated side in a sling for about 24 hours.
- Avoid vigorous shoulder movement or sudden jerking of that arm for the advised weeks to prevent lead displacement.
- Teach daily radial pulse for one full minute; a rate below the programmed minimum, dizziness, syncope, hiccups or wound signs must be reported promptly.
- Electromagnetic safety: keep mobile phones on the opposite ear or more than 15 cm from the device, avoid strong magnetic fields, welding and transformers, and inform airport security staff carrying the pacemaker card; MRI is avoided unless the device is MRI-conditional.

## Common confusion
Students confuse the sensing and pacing functions. A modern pacemaker works on demand — it senses the patient's own rhythm and paces only when the intrinsic rate falls below the lower programmed limit, so a pulse near that limit is expected and normal. Also, passing through an airport doorway metal detector is generally acceptable if the patient walks through briskly and does not linger; it is the handheld security wand held over the device that should be avoided.

## Exam-focused takeaway
Examiners test the education points hardest: daily one-minute pulse check, arm sling and restricted shoulder movement after implantation, mobile phone use on the opposite side, carrying the pacemaker identification card, and battery replacement by elective procedure every few years. MCQs may ask which activities or environments interfere with pacemakers, and viva questions often cover VVI versus DDD in one line each.

## Frequently asked questions

### Why should a pacemaker patient check the pulse daily?
Counting the radial pulse for one full minute each morning verifies that the device maintains at least the programmed lower rate. A consistently lower rate or giddiness needs review.

### What restrictions follow pacemaker implantation?
The arm on the operated side is supported in a sling for about a day, and strenuous shoulder movement and heavy lifting are restricted as advised. This protects the fresh lead.

### Can pacemaker patients use mobile phones and household appliances?
Ordinary microwaves and televisions are safe. Mobiles are held to the ear opposite the device and never carried in a pocket over it, keeping at least 15 cm away.

### Is MRI safe with a pacemaker?
Conventional systems are avoided because the magnetic field can reprogram the circuitry; only certified MRI-conditional devices under strict protocol are permitted. The device card must confirm this first.

### What are the signs of pacemaker malfunction or infection?
Dizziness, fainting, a pulse below the set minimum, unexplained fatigue, plus fever or wound redness over the pocket. Any of these warrants immediate medical contact.
