Sydäntahdistimet

Sydäntahdistimet, also known as pacemakers, are small electronic devices implanted in the body to help regulate abnormal heart rhythms. They are typically used when the heart beats too slowly, too fast, or irregularly, a condition known as arrhythmia. The primary function of a pacemaker is to ensure the heart maintains a consistent and appropriate heart rate.

The device consists of a pulse generator containing a battery and circuitry, and one or more leads that are inserted through veins into the heart chambers. These leads monitor the heart's electrical activity and deliver electrical impulses when necessary to stimulate the heart muscle to contract. Modern pacemakers are sophisticated and can be programmed to adapt to a person's activity level, increasing or decreasing the heart rate as needed.

Pacemaker implantation is a common surgical procedure performed under local anesthesia. The pulse generator is usually placed in a pocket created under the skin, typically in the upper chest area. After implantation, regular check-ups are necessary to monitor the device's function and battery life, which typically lasts for several years before replacement. Sydäntahdistimet significantly improve the quality of life for individuals suffering from heart rhythm disorders, alleviating symptoms such as fatigue, dizziness, and fainting, and allowing them to lead more active lives.
