A pacemaker is a small battery-operated device that is implanted under your skin, near the heart. It monitors your heart rate, as well as regulate your heartbeat by sending small electrical pulses to your heart. Some pacemakers can also record your heartbeat to help your doctor better understand your heart rhythm.
Most pacemakers comprise of two components. The first component is the pulse generator, which is responsible for generating the electrical pulses. The second is the pacing lead, which is a small wire running from the pulse generator to the heart. The lead carries the electrical signals from the pulse generator to regulate your heartbeat.
There are two types of pacemakers commercially available:
- Single chamber pacemakers. One pacing lead is used to carry electrical pulses to the heart’s left or right atrium.
- Dual-chamber pacemakers. Two pacing leads are used. One will be placed in the right atrium and the other in the left atrium.
While pacemakers are recommended for people with an irregular heartbeat, you may also need one if you:
- Have a congenital heart disease.
- Recently had a heart attack.
- Are taking certain heart medicines, such as beta-blockers.
If you are suffering from any of the above, send us an enquiry to find out if you need a pacemaker.
