What is a dual pacemaker?

Dual chamber pacemaker is a small, electrical device that can be implanted in the chest to regulate the heart rhythm. It works by generating electrical pulses that are sent to the right atrium and right chamber of the heart, stimulating contractions and allowing both chambers to maintain rhythm. Cardiostimulators can significantly improve symptoms and increase life expectancy in patients who have a dangerously slow heart rate, congenital heart defects or complications from heart failure. A double chamber pacemaker is essential when the heart is too weak to maintain the timing of the right atrium and the chamber. The first electrical pulse in a series signals a hall that pumps de-oxgenated blood into the chamber. The second pulse triggers the chamber to pump blood into the lungs so that it can be oxygenated and re -inserted into the heart.

The main body of the pacemaker with a double chamber, called a generator, is usually less than 2 inches (about 5 centimeters) on average. The battery generator is equipped with memoryThe chip that stores information and signals the release of electricity. Two wires run from the generator to the heart. Batteries in modern pacemakers usually last at least 10 years. When the battery starts low, the surgeon can implant a new generator and reconnect the wires that are already in place.

In most cases, surgery of pacemaker with a double chamber may be carried out in a specialized clinic or general hospital in about an hour. Before the procedure, the patient is to injection of localized anesthetics in the chest to duplicate the area. A small cut is made on the left side of the chest and the two -chamber pacemaker is secured just below the skin. With the help of an X -ray X -ray performance in a real timeg, the surgeon leads two wires to a subclavian vein and directs them to their appropriate chambers in the heart. The wires are connected to the pacemaker and tested before the closure of surgical scars.

After the procedure, most patients must remain in the hospital for at least one day so that doctors can monitor their conditions and ensure that their pacemakers work properly. Frequent subsequent visits in the first six months are important to see if you need to set the cardiac settings. When patients react well in a six -month period, they may have to visit checks only once or twice a year. When deciding on an intelligent lifestyle and participating in the planned visits of doctors, most people who receive pacemakers are able to extend their lives by years or even decades.
