Pacemakers and defibrillators — what they do and what life looks like after

This article is for educational purposes only and does not constitute medical, legal, or financial advice. Every family situation is different, and you should consult with appropriate professionals about your specific circumstances.

Your parent's cardiologist has recommended a pacemaker or a defibrillator, and the word device carries a particular kind of weight. A device. In the chest. Electrical impulses. Surgery. It sounds sci-fi and serious and permanent in a way that pills somehow don't feel. Your parent might be thinking about having something foreign inside their body, about what happens if it breaks, about whether they'll be normal anymore. You might be thinking about whether this is necessary, whether it's major surgery, whether your parent will survive the procedure.

Step back for a second. Pacemakers and defibrillators are among the most successful interventions in modern medicine. Millions of people have them. They work brilliantly. Most people feel dramatically better after getting one. The procedure itself is usually quick and well-tolerated. The recovery is usually easy. This is not a last-ditch desperate measure. This is a really good solution to a specific problem.

The fear around having a device implanted is understandable. But understanding what the device does and how it works and what recovery looks like will help your parent make peace with the decision and help you support them through it.

What These Devices Actually Do

A pacemaker is a small, battery-powered device that helps regulate your heart's rhythm. Your parent's heart normally has its own electrical system that tells the heart when to beat. If that system is malfunctioning—if the heart is beating too slowly, or if the electrical signal isn't getting where it needs to go—the heart might not be pumping efficiently or at all. A pacemaker sends electrical impulses to the heart to trigger contractions at an appropriate rate.

A defibrillator, sometimes called an ICD (implantable cardioverter-defibrillator), does more. It monitors the heart's rhythm and can deliver a shock if the heart develops a dangerous, life-threatening rhythm. It's basically a cardiac arrest prevention device. If your parent's heart starts fibrillating or doing another dangerous arrhythmia, the defibrillator detects it and delivers an electrical shock to reset the heart back to a normal rhythm.

Some people get pacemakers alone. Some get defibrillators alone. Some get a device that combines both functions, called a CRT (cardiac resynchronization therapy) device, which also helps both sides of the heart beat in better coordination. The specific device your parent needs depends on what their heart problem is.

Why would your parent need a pacemaker? The heart's electrical system can slow down. Sometimes the signal from the upper chambers to the lower chambers gets blocked, called a heart block. Sometimes the heart's natural pacemaker, the SA node, just fires too slowly, a condition called sick sinus syndrome. Sometimes people have fainting episodes because their heart rate drops dangerously low. These situations can be life-threatening—if the heart beats too slowly, it can't pump enough blood to the brain and your parent can lose consciousness. A pacemaker prevents this by making sure the heart beats at an adequate rate.

Why would your parent need a defibrillator? If they've had a heart attack and the damaged scar tissue is prone to developing dangerous arrhythmias, or if they have certain inherited conditions that make dangerous arrhythmias likely, or if they've already had a life-threatening arrhythmia and survived it, a defibrillator can be life-saving. It's prevention for cardiac arrest.

Both devices improve quality of life and prevent death. These are not things to be ambivalent about.

The Procedure and Recovery

The procedure to insert a pacemaker or defibrillator is usually outpatient surgery. Your parent goes to the hospital, gets local anesthesia at the placement site (usually under the collarbone), and the cardiologist or cardiac surgeon makes a small incision and guides the leads through a vein to the heart. The generator,the actual device,is placed under the skin, and the leads are attached to the generator. The whole procedure usually takes an hour or so, sometimes less.

Your parent is usually awake during this procedure, though sedated. They might feel pressure or tugging but not pain. They might hear the doctor asking them to take a deep breath or cough to help position something. It's not as bad as it sounds. Many patients say the anticipation was worse than the actual procedure.

After the procedure, your parent goes to recovery for a few hours, then usually goes home the same day. The incision is small, maybe an inch and a half, and it's usually closed with dissolvable stitches. There's typically some soreness and bruising at the site for a week or two, but this is mild compared to what people expect.

Recovery is surprisingly quick. Your parent might feel tired the first few days, but within a few days to a week, most people feel pretty much normal. They're restricted from heavy activity for a few weeks,no lifting more than ten to fifteen pounds, no reaching overhead with the arm on the side of the pacemaker, no swimming or submerging the incision until it's fully healed. After those restrictions are lifted, your parent can go back to normal activities.

Many people report feeling better almost immediately after device implantation. If they were experiencing fainting spells or severe fatigue from a slow heartbeat, those symptoms resolve as soon as the device is working. If the device is preventing dangerous arrhythmias, your parent doesn't feel it doing so, but the security of knowing they're protected is genuinely psychologically helpful.

Living With the Device

Your parent's life does not fundamentally change after getting a pacemaker or defibrillator, but there are some practical considerations.

The device has a battery that lasts roughly five to ten years depending on how much the device is working. When the battery gets low, the device needs to be replaced. This is a simpler procedure than the original insertion because the leads are already there. The generator just gets replaced, which takes even less time than the original procedure. Your parent will get regular check-ups that monitor the battery level, so the replacement never happens as a surprise.

Your parent needs to avoid strong magnetic fields, including MRI machines. This used to be an absolute contraindication, but modern devices are often MRI-safe, especially newer ones. Your parent should carry an ID card that indicates what device they have, and should always tell medical personnel about the device so they can decide whether any particular scanning or imaging is safe. In most emergency situations, an alternative imaging method to MRI can be found, so this is not as limiting as it sounds.

Airport security sometimes reacts to the metal in the device, setting off metal detectors. Your parent should mention the device to security so they can do a hand-wand search instead of sending them through a metal detector. This is quick and not a big deal.

Some electronics can interfere with pacemakers, though this is less of an issue with modern devices. Your parent should avoid holding cell phones directly against the side of the body where the device is implanted. Very powerful magnets, like those used in industrial settings, should be avoided. But normal household electronics,microwaves, televisions, computers,are fine. Your parent can use tools, can work in yards, can live a normal life.

Your parent needs regular follow-up appointments with the cardiologist for device checks. These appointments involve checking how well the device is working, how it's sensing the heart's rhythm, how the battery is doing. Some devices can be checked remotely now, which is incredibly convenient. Your parent can have a remote monitor in their home, and data from the device uploads automatically, so some check-ups can be done without going to the office.

If the device is a defibrillator, your parent needs to understand what to do if it delivers a shock. Most shocks feel like a kick in the chest, strong and startling. After a shock, your parent should call their cardiologist immediately. The shock means a dangerous rhythm occurred, and that information is important for managing the condition. Your parent should not be alarmed if this happens,it means the device did exactly what it's supposed to do.

The Hard Ethical Question

This is the part that's uncomfortable to talk about, but it's important. At the end of life, when your parent is dying and the devices are not preserving quality of life anymore, there's a question of whether to disable the device or let it continue attempting to restart the heart.

If your parent has a defibrillator and is dying of an illness like advanced cancer or end-stage dementia, the defibrillator might keep giving shocks to try to restart the heart when it stops. This can prevent a peaceful death. Some people don't want that. They want to be allowed to die peacefully when the time comes.

This is a conversation worth having with your parent while they're well and able to express their values. Do they want the device to be disabled at end of life? Do they want everything done to keep them alive as long as possible? The answers matter, and the time to discuss it is before the crisis, not during it.

If your parent is in the hospital dying, the doctors can disable the defibrillator so it doesn't continue shocking the heart if it stops. This is ethical and appropriate at the end of life. But it helps if your parent has already expressed that this is what they want, and if you know this is what they want, so you can advocate for it if they can't speak for themselves.

This is not a common occurrence, but it's real, and it's worth thinking about.

Normalizing It

Here's the thing: more people than you realize have pacemakers or defibrillators. Your parent's neighbor probably has one. Your parent's friend from church probably has one. The friend from your parent's exercise class definitely has one. These devices are common, and most people adjust to having them quickly.

Many people report that the device gives them freedom rather than restricting it. Before the device, they were limited by symptoms,fainting, fatigue, fear of the heart stopping. After the device, those limitations are gone. They can exercise more. They can be more active. They can live with less fear.

Your parent might worry about whether people will judge them for having the device, or whether it makes them seem weak or old. This is understandable, but it's not something that usually becomes an issue. The device is internal. No one knows about it unless your parent tells them. It doesn't change how your parent looks or how they interact with the world. It just quietly does its job.

The psychological adjustment to having a device can take some time, especially if your parent is someone who resists depending on medical technology. Some people mourn the loss of a "normal" body. Some people feel relief that a problem has been solved. Most people probably feel both at different moments. These feelings are valid and normal.

Your role includes normalizing the device for your parent. Not minimizing the reality that they have a device in their chest, but helping them see it as a tool that improves their life, not a sign that something is fundamentally broken about them.

Many people live for decades with pacemakers or defibrillators. They work, they raise families, they travel, they retire, they enjoy their lives. The device becomes something they sometimes think about, like glasses if they wear them, or a chronic medication if they take one. It's part of their medical care, but it's not their identity.
