The heart machine that helps the heart beat at the correct pace is called a pacemaker.
Understanding Pacemakers
A pacemaker is a small, battery-operated device designed to regulate the heartbeat, particularly when the heart beats too slowly.
How Pacemakers Work
- Sensing Heartbeat: The pacemaker continuously monitors the heart's natural rhythm.
- Sending Signals: When it detects that the heart is beating too slowly, it sends electrical signals to the heart.
- Regulating Beat: These signals stimulate the heart, causing it to beat at the correct pace.
Key Features of a Pacemaker
- Battery-Operated: Pacemakers are powered by a small, long-lasting battery.
- Implantable: They are typically implanted under the skin, near the collarbone.
- Programmable: Doctors can adjust the settings of a pacemaker to meet the specific needs of the patient.
Importance of Pacemakers
Pacemakers are vital for individuals with certain heart conditions. They help maintain a regular heart rhythm, ensuring that the body receives an adequate blood supply. This can alleviate symptoms such as fatigue, dizziness, and shortness of breath, significantly improving the quality of life.
Who Needs a Pacemaker?
Pacemakers are typically recommended for people with:
- Bradycardia: A condition characterized by a slow heart rate.
- Heart Block: A problem with the heart's electrical system that disrupts the normal heartbeat.
- Other Arrhythmias: Irregular heartbeats that can be managed with a pacemaker.
