Biventricular Pacemaker Implantation

A biventricular pacemaker implantation is a procedure to place (implant) a pacemaker into both of the lower chambers (ventricles) of the heart. A pacemaker is a small, battery-powered device that helps control the heartbeat. If the heart beats irregularly or too slowly (bradycardia), the pacemaker will pace the heart so that it beats at a normal rate or a programmed rate. Parts of a biventricular pacemaker include:
• Pulse generator. The pulse generator contains a small computer and a memory system that is programmed to keep the heart beating at a certain rate. The pulse generator also produces the electrical signal that triggers the heart to beat. This is implanted under the skin of the upper chest, near the collarbone.
• Wires (leads). The leads are placed in the left and right ventricles of the heart. The leads are connected to the pulse generator. They transmit electrical pulses from the pulse generator to the heart.
This procedure may be done to treat:
• Bradycardia.
• Symptoms of heart failure.
• Loss of consciousness that happens repeatedly (syncope).
• Shortness of breath (dyspnea) due to heart problems.

• Any allergies you have.
• All medicines you are taking, including vitamins, herbs, eye drops, creams, and over-the-counter medicines.
• Previous problems you or members of your family have had with the use of anesthetics.
• Any blood disorders you have.
