Heart Failure and Biventricular Pacemakers
How Do I Prepare for a Biventricular Pacemaker Implant?
Ask your doctor what medications you are allowed to take before your pacemaker is implanted. Your doctor may ask you to stop certain drugs several days before your procedure. If you have diabetes, ask your doctor how you should adjust your diabetic medications.
Do not eat or drink anything after midnight the night before the procedure. If you must take medications, drink only small sips of water to help you swallow your pills.
When you come to the hospital, wear comfortable clothes. You will change into a hospital gown for the procedure. Leave all jewelry and valuables at home.
What Happens During the Pacemaker Implantation?
Pacemakers can be implanted two ways:
Inside the heart (endocardial, transvenous approach): This is the most common and simple technique used. A lead is placed into a vein (usually under your collarbone), and then guided to your heart. The tip of the lead attaches to your heart muscle. The other end of the lead is attached to the pulse generator, which is placed under the skin in your upper chest. This technique is done under local anesthesia (you will not be asleep).
Outside the heart (epicardial approach): Your chest will be opened and the lead tip is attached to the outside of the heart. The other end of the lead is attached to the pulse generator, which is placed under the skin in your abdomen. This technique is done under general anesthesia (you will be asleep) by a surgeon.
Your doctor will decide which approach is best for you, although almost all patients receive the transvenous approach.
