Biventricular cardiac pacemaker
Updates to Article Attributes
Body
was changed:
Biventricular cardiac pacemakers, also known as cardiac resynchronisation therapy (CRT), refers to surgically implanted cardiac conduction devices with one lead in each ventricle. Used mainly in patients with severe cardiac failure not well controlled on maximal medication therapy.
Components
- lead in the right atrium
- lead in the right ventricle
- lead in the coronary sinus
veinto pace the left ventricle
Function
When the heart rate drops below a certain predetermined rate, the device generates electrical impulses that stimulate both ventricles to contract simultaneously, thus improving cardiac output.
