The type of pacemaker you may need depends on your symptoms and the specific heart condition you have. After our diagnostic evaluation, we discuss our recommendations with you to choose the right pacemaker for your needs. This type of pacemaker has one lead that connects the pulse generator to one chamber of your heart.

Modern Pacemakers

For most people, we use the single-chamber pacemaker to control heartbeat pacing by connecting the lead to your right ventricle lower heart chamber. Depending on your symptoms and the type of pacing you need, we connect the lead to your right atrium upper heart chamber to stimulate the pacing in that chamber. With two leads, this device connects to both chambers on the right side of your heart, the right atrium and the right ventricle. The doctor programs the dual-chamber pacemaker to regulate the pace of contractions of both chambers. This pacemaker helps the two chambers work together, contracting and relaxing in the proper rhythm.

The contractions allow blood to flow properly from the right atrium into the right ventricle.

Depending on the pacing needs of your heart, a dual-chamber device may be an appropriate option for you. This pacemaker, also known as a cardiac resynchronization therapy CRT device, has three leads connected to the right atrium and both ventricles. We use the biventricular pacemaker to treat people with arrhythmias caused by advanced heart failure.

For many people with heart failure, the left and right ventricles do not pump at the same time. Our doctors program the biventricular pacemaker to coordinate the contractions of the ventricles, so that they both pump together. Implanting the pacemaker requires a minor surgical procedure performed in the cardiac catheterization laboratory.

Your doctor will discuss the implantation with you prior to the procedure. Once you and your doctor have discussed the procedure and you've had any questions answered, you'll be asked to sign an informed consent form. A pacemaker implantation procedure may be performed on an outpatient basis or as part of a stay in a hospital. The entire procedure usually lasts about two hours. During the procedure, patients will lie flat on a table for the duration of the implantation. The upper chest will be scrubbed and shaved if needed and patients will be covered with sterile sheets.

Access to the vein under the collar bone is obtained and one or more leads thin wire-like tubes are advanced to the heart. The leads are connected to the pacemaker and closed under the skin. Once the lead has been positioned, the doctor will make a two- to three-inch incision in the skin, creating a small "pacemaker pocket. The doctor will suture the incision over the pacemaker and place a dressing over it. If the procedure is performed on an outpatient basis, patients may be allowed to leave after completing the recovery process.

However, if there are concerns or problems with the ECG, patients may stay in the hospital for an additional day or longer for monitoring of the ECG. Patients should be able to return to their daily routine within a few days. The doctor will tell you if you will need to take more time in returning to normal activities. In addition, patients should not do any lifting or pulling on anything for a few weeks.

Patients may be instructed not to lift arms above the head for a certain period.

Patients will most likely be able to resume their usual diet, unless the doctor instructs differently. If you notice signs of infection or bleeding on your incision site and seek medical attention, do not let anyone insert a needle into the area around the device to remove or collect fluid as this may result in an infection. Activity on the side of the pacemaker should be limited for week six weeks recommended for biventricular pacemaker as follows:.

Cover the pacemaker site if in direct sunlight as the metal of the device will warm beneath the skin. Electromagnetic fields can interfere with the pacemaker's ability to sense an abnormal rhythm. Some devices and machines are safe to use while other devices are not:. Carry your pacemaker identification card in your wallet at all times. You will be given a temporary card upon discharge.

A permanent card will be mailed to you from the pacemaker manufacturer in weeks.

  • Please notify your pacemaker manufacturer if you have a new address or phone number. Their toll-free phone number is on the temporary and permanent identification card. It is very important that you have your pacemaker checked regularly 4 to 6 weeks after implant and every 6 months thereafter. It is recommended that you know your pacemaker parameters.

    We will tell you what heart rate your pacemaker parameters and answer any questions that you may have regarding your device programming upon discharge or during your first clinic visit for a wound check or device check. Some devices are equipped with remote monitoring capabilities where you can send information about your pacemaker from home that the clinic can view.

    We recommend that you have this capability for your routine device surveillance.

    We will discuss with you at your clinic visit. You should lie down immediately, make sure you are in a safe environment, away from any machines or moving vehicles, and call a friend or family member, or call , if you feel any of the following symptoms:. Stanford Arrhythmia Service: - for questions or problems available 24 hours a day, 7 days a week. In the past, people with pacemakers risked interference with the proper functioning of their pacemakers if they were too close to car distributors, radar, microwaves, electric blankets, and airport security detectors.

    However, with improvements in pacemaker technology, these issues are no longer of major concern. The following precautions should always be considered. Discuss the following in detail with the doctor:. Always consult your doctor if you have any questions concerning the use of certain equipment near your pacemaker. Once the pacemaker has been implanted, people with pacemakers should be able to do the same activities everyone else in their age group is doing.

    When involved in a physical, recreational, or sporting activity, a person with a pacemaker should avoid receiving a blow to the skin over the pacemaker. A blow to the chest near the pacemaker can affect its functioning. See your doctor if a blow to chest is received near the pacemaker. Always consult with the doctor when feeling ill after an activity, or if there are questions about beginning a new activity.

    Although the pacemaker is built to last several years, always check the device regularly to ensure that it is working properly. The pulse rate is a measurement of the heart rate, or the number of times the heart beats per minute. As the heart pushes blood through the arteries, the arteries expand and contract with the flow of the blood. The normal pulse rate for healthy adults ranges from 60 to beats per minute. The pulse rate may fluctuate and increase with exercise, illness, injury, and emotions.

    Girls ages 12 and older and women, in general, tend to have faster heart rates than do boys and men. Athletes, such as runners, who do a lot of cardiovascular conditioning may have heart rates in the 40s and experience no problems. As the heart forces blood through the arteries, you feel the beats by firmly pressing on the arteries, which are located close to the surface of the skin at certain points of the body.

    The pulse can be found on the side of the lower neck, on the inside of the elbow, or at the wrist. The major objective of this book is to present, in expanded form, the lectures given by internationally known basic and clinical researchers in the field of artificial pacing of the heart and to make that information available to a wider public. The experience discussed covers the principles and main methods of pacing using implantable and external, fixed rate, R-wave or P-wave triggered pacemakers with electrodes placed in the myocardium either surgically or transvenously, and powered by zinc-mercury oxide or rechargeable batteries.

    Particular emphasis was put on problems of pressing importance at the present time, such as the increase of pacemaker longevity with lithium- iodide and nuclear-powered batteries or improved electrodes, as well as the postoperative management of a steadily increasing number of pacemaker patients.
