Pacemaker

An electric pacemaker (electric + pacemaker; synonym: artificial pacemaker, pacemaker) is a device designed to artificially stimulate the heart using electrical impulses. It is used for heart rhythm disturbances, when the natural electrical activity of the heart is weakened or completely absent.

A pacemaker consists of a pulse generator and one or more electrodes. The pulse generator is placed under the skin in the subclavian region or in the abdominal cavity. A connecting wire extends from it to an electrode, which is placed in the heart cavity or on its surface.

An electrical impulse from the generator passes through the electrodes to the heart muscle, causing it to contract. The frequency of electrical stimulation is selected individually for each patient. Modern pacemakers can automatically change the pacing rate depending on the patient's needs.

Pacemakers significantly improve the quality of life of patients with cardiac arrhythmias by allowing the heart muscle to function adequately. Their use helps prevent life-threatening conditions associated with arrhythmia.

A pacemaker, also called a pacemaker or electronic pacemaker, is an electronic device that creates electrical signals that stimulate the heart to maintain a normal heart rhythm. The use of such devices has become particularly common for the treatment of bradycardia (slow heart rate), tachycardia (increased heart rate) and cardiac cycle disorders (eg, Wolff-Parkinson-White syndrome). ES are typically used as a permanent device placed under the skin, sometimes through surgery or another safe method such as a percutaneous insert that can be inserted through the arm or neck. All modern stimulators usually have the ability to continuously magnetically recharge to further extend battery life.
