What is a pacemaker for?

a human heart

A pacemaker is a medical device that is used to treat abnormal heart rhythms or arrhythmias. It is a small device that is implanted under the skin, usually in the chest or abdomen, and connected to one or more wires or leads that are threaded through a vein into the heart.

The pacemaker sends electrical signals to the heart, which helps it beat at a regular rhythm and maintain a healthy heart rate. The device works by monitoring the heart's electrical activity and delivering a small electrical impulse whenever necessary to keep the heart functioning properly.

Pacemakers are typically used for people with bradycardia, a condition where the heart beats too slowly, or for people with other heart rhythm disorders. They can also be used in conjunction with other heart treatments such as medication or surgery.

Modern pacemakers are very advanced and include features such as remote monitoring, where the doctor can check the device’s performance and adjust settings remotely. They can also include multiple leads to pace multiple chambers of the heart, and can adjust the pacing rate in response to activity levels or other factors.

Pacemakers are generally very safe and can greatly improve the quality of life for people with heart conditions. However, they do require ongoing monitoring and follow-up care to ensure they are functioning properly and to make any necessary adjustments.
