You'll be attached to a special monitor so the medical team can keep an eye on your heart rhythm.
The monitor consists of a small box connected by wires to your chest with sticky electrode patches.
The box displays your heart rhythm on several monitors in the nursing unit. The nurses will be able to observe your heart rate and rhythm.
A chest X-ray will be carried out to check your lungs, as well as the position of the pacemaker and leads.
You may feel some pain or discomfort during the first 48 hours after having a pacemaker fitted, and you'll be given pain-relieving medication.
There may also be some bruising where the pacemaker was inserted. This usually passes within a few days. Tell the staff if your symptoms are persistent or severe.
Most people are able to go home on the same day they have the procedure. Occasionally, some people stay a day or two in hospital.
You'll need to arrange for someone to pick you up from hospital and take you home.
Before going home, you'll be given a pacemaker registration card, which has the details of the make and model of your pacemaker. Always carry the card with you in case of an emergency.
You may also want to wear a MedicAlert bracelet or necklace engraved with important information, such as the type of pacemaker you have, a personal identity number and a 24-hour emergency phone number.
If you have an ordinary driving licence, you can start driving again after 1 week as long as:
You must also tell the Driver & Vehicle Licensing Agency (DVLA) and your insurance company that you have a pacemaker.
If you drive a large or passenger-carrying vehicle, you'll have to wait 6 weeks after your pacemaker is fitted before driving again.
You may be able to feel the pacemaker and it may feel uncomfortable when you lie in certain positions, but you'll soon get used to it.
Modern pacemakers are now so small they're almost completely hidden by the chest tissue and are barely noticeable.
You should feel back to your usual self, or even better, very quickly.
It's best to avoid reaching up on the side you had your operation for 4 to 6 weeks. That means not hanging out washing or lifting anything from a high shelf, for example.
But it's important to keep your arm mobile by gently moving it to avoid getting a frozen shoulder. A physiotherapist can show you how to do this.
You'll usually be able to do all the things you want to do after around 4 weeks.
The time you need off work will depend on your job. Your cardiologist will usually be able to advise you about this.
Typically, people who have had a pacemaker fitted are advised to take 3 to 7 days off.
People who drive for a living, such as bus and lorry drivers, won't be allowed to drive these types of vehicles for 6 weeks after the pacemaker is fitted.
You should avoid strenuous activities for around 4 to 6 weeks after having your pacemaker fitted. After this, you should be able to do most activities and sports.
But if you play contact sports such as football or rugby, it's important to avoid collisions. You may want to wear a protective pad.
Avoid very energetic activities, such as squash.
Don't get your wound wet until your stitches have been taken out. After that, avoid wearing anything that rubs against the area of your wound, such as braces.
Women may need a new bra with wider straps. Avoid exposing your wound to sunlight in the first year as this can cause a darker scar.
It depends on the kind of stitches used. Many doctors use soluble stitches that dissolve on their own. Before you go home, you'll be told what type of stitches you have.
If you need to have your stitches removed, it'll usually be after about 7 to 10 days.
You'll usually have your pacemaker checked after 4 to 6 weeks at the hospital where it was fitted.
Provided this check is satisfactory, you'll have your pacemaker checked every 3 to 12 months.
If after having the pacemaker fitted and leaving hospital you feel you're not getting as much benefit as you imagined, your pacemaker may need some small adjustments.
The cardiologist or cardiac technician will be able to do this.
Signs that your pacemaker isn't working as it should or you have developed an infection or blood clot include:
Contact your GP or cardiologist as soon as possible for advice if you experience any of these problems after having a pacemaker fitted.
Anything that produces a strong electromagnetic field, like an induction hob, can interfere with a pacemaker.
Most common household electrical equipment, such as hairdryers and microwave ovens, won't be a problem, as long as you use them at least 15cm (6 inches) away from your pacemaker.
If you have an induction hob, keep a distance of at least 60cm (2ft) between the stove top and your pacemaker.
If this is a problem, you may want to consider replacing the appliance with something more suitable.
If you feel dizzy or feel your heart beating faster while using an electrical appliance, simply move away from it to allow your heart beat to return to normal.
Read on for some advice on using common electrical devices.
It's safe to use a mobile phone, but make sure you keep it more than 15cm (6 inches) from your pacemaker. Use a headset or the ear on the opposite side to the pacemaker.
Walking steadily through an anti-theft detector in a shop doorway shouldn't affect your pacemaker, but don't stand too close to this type of security device for long.
Airport security systems don't usually cause problems with pacemakers, but carry your pacemaker identification card with you and tell security staff you have a pacemaker.
Security staff in some countries may insist you pass through the scanner. Move quickly through it and don't linger nearby.
Handheld metal detectors shouldn't be placed directly over your pacemaker.
MRI scanners aren't usually used for people with pacemakers because they produce strong magnetic fields.
MRI-safe pacemakers and implantable cardioverter defibrillators (ICDs) are becoming more common.
Other types of medical tests are safe, but always tell the person treating you that you have a pacemaker.
TENS machines shouldn't be used without first consulting your pacemaker clinic or manufacturer. They produce small electrical impulses that could interfere with your pacemaker.
If your job brings you into contact with strong electrical fields, such as arc welding, diathermy or working with high-power radio or TV transmitters, or you have direct contact with car ignition systems, check with your cardiologist or pacemaker technician before returning to work.
Avoid wearing magnetic bracelets and magnets near your chest.
Most pacemaker batteries last for 6 to 10 years. After this, you may need to have the batteries changed.
Ask your doctor how you'll know when the battery needs to be replaced or recharged.
Changing the batteries involves replacing the pacemaker box with a new unit. This is a simple procedure that may or may not require an overnight stay in hospital.
The original lead or leads can usually be left in place, although occasionally they'll also need to be replaced.
You'll need follow-up appointments for the rest of your life after having a pacemaker fitted.
These may be every 3 to 12 months, depending on the type of pacemaker you have and how well it works.
At your follow-up appointment, the technician or doctor will analyse the discharge rate of your pacemaker, measure the strength of the electrical impulse, and record the effects of the impulse on your heart.
Most modern pacemakers can store information about the state of the battery and the performance of the pulse generator.
Your pacemaker can then be reprogrammed to the best settings for you, if necessary.
There's no reason you can't continue to have a good sex life after having a pacemaker implanted and you're feeling better.
But you should avoid positions that place pressure on the arms and chest for the first 4 weeks of your recovery.
The risk of sex triggering a heart attack is low (around 1 in 1 million).
You should also tell your family and close friends that you have a pacemaker fitted. Tell them what to do if you lose consciousness or collapse.
Most people who have a pacemaker fitted feel it has a tremendously positive impact on their life.
Having a pacemaker can help you be more active. It may also help you stay out of hospital and live longer.
Above all, you should feel better. Previous symptoms, such as breathlessness or dizziness, should disappear.
