Dual Chamber Pacemakers: Enhancing Cardiac Function
A dual chamber pacemaker is a medical device designed to provide simultaneous moderation and stimulation to both the upper and lower chambers of the heart. These pacemakers utilize leads to transmit electrical pulses from the generator to both the right atrium (the upper right chamber) and the right ventricle (the lower right chamber).
Biventricular Pacemaker
The biventricular pacemaker, also known as the cardiac resynchronization therapy (CRT) device, is a highly sophisticated pacemaker that utilizes three leads. It is primarily used for the treatment of heart failure. During the implantation procedure, the doctor strategically places the leads in three specific locations – the right ventricle, right atrium, and the coronary sinus vein. By pacing the left ventricle, these electrical impulses stimulate both lower chambers of the heart, resulting in synchronized contractions. This synchronization promotes a balanced and improved cardiac function, thereby providing significant benefits to patients with heart failure.
