Overview: A pacemaker is a battery-powered device that sends electrical signals to your heart to help it beat at a proper rhythm. The pacemaker is surgically placed under your skin, beneath your collarbone, and is connected to your heart by one or more or leads. Depending on your heart condition, your doctor will either recommend a single or dual chamber pacemaker. For dual chamber, both the right atrium and right ventricle are paced. This requires two pacing leads. One of which is placed in the right atrium, and another which is placed in the right ventricle.
Dual chamber pacemakers are used to treat bradycardia and atrial fibrillation associated with bradycardia.Learn More
During the surgery, one or more flexible, insulated wires (leads, or electrodes) are inserted into a major vein under or near your collarbone and guided to your heart with the help of X-ray images. One end of each wire is secured to the appropriate position in your heart, while the other end is attached to the pulse generator, which is usually implanted under the skin beneath your collarbone.
Bradycardia- Refers to abnormally slow heartbeats. Bradycardia may result when electrical signals are not produced faster than required, or when these signals do not reach your heart’s ventricles.
Atrial fibrillation- Refers to irregular heartbeat in which abnormal electrical signals originate in the atria. Atrial fibrillation can result in the rate of the lower chambers to slow down, thus causing bradycardia.
