Cardiac Pacing

For patients whose heart is beating too slowly will require a pacemaker. Cardiac pacemaker is an electronic device used to stimulate the heart to beat at a programmed rate. It is about 2 inches in diameter and 1/3 inch thick, and consists of a battery (usually lasts 5 to 10 years), electronic components, and pacing leads to convey electrical signals between the pacemaker and the heart.

One or two pacing leads are used depending on the medical condition.

During the operation, pacing leads are inserted into a vein and guided to the heart under fluoroscopy. The leads are then connected to the pacemaker which is implanted under the skin. The procedure takes 1 to 2 hours and the patient is hospitalized for one to a few days. Patients with pacemakers can return to normal lives. However, regular follow-up with the cardiologist is required.

Since the battery usually lasts for 5 to 10 years, patients would have to undergo the operation again once the battery has run down.
