Upper chest passmaker inplantation2/25/2023 These are slow heart rhythms that may arise from disease in the heart's electrical conduction system (such as the SA node, AV node or HIS-Purkinje system). Pacemakers are usually used to treat the following: Your doctor will do tests to find out for sure. If your heart is having trouble maintaining its own rhythm, you may need one. This causes the heart muscle to contract, creating a heartbeat. When your heart rate drops below that set rate, your pacemaker generates (fires) an electrical impulse that passes through the lead to the heart muscle. The doctor will program your minimum heart rate. Biventricular pacemaker uses three leads: one placed in the right atrium, one placed in the right ventricle, and one placed near the left ventricle.Dual-chamber pacemakers use one lead in the atria and one lead in the right ventricle of your heart.Single chamber pacemakers use one lead in the upper chambers (atria) or lower chambers (ventricles) of the heart.The pacemaker may have one to three leads, depending on the type of pacemaker needed to treat your heart problem. They send impulses from the pulse generator to the heart muscle, as well as sense the heart's electrical activity.Įach impulse causes the heart to contract. The leads are wires that are threaded through the veins into the heart and implanted into the heart muscle. The pulse generator houses the battery and a tiny computer, and resides just under the skin of the chest. The pacemaker has two parts: the leads and a pulse generator. Often, a pacemaker device can correct it. But some hearts don't beat regularly, a problem called arrhythmia. The heart has its own pacemaker that regulates the rate at which it beats. The healthy heart has its own pacemaker that regulates the rate at which the heart beats. It is implanted just under the skin of the chest during minor surgery. A pacemaker may also be used to treat fainting spells (syncope), congestive heart failure, and, rarely, hypertrophic cardiomyopathy. A pacemaker is a small device that sends electrical impulses to the heart muscle to maintain a suitable heart rate and rhythm.
