What kind of pacemakers are available

This moves blood through your heart, to your lungs, allowing oxygenated blood back in, and then forcefully pumping it out to your body and brain. If the electrical impulses are interrupted for any reason, your heart rate can go too slowly and that may make a pacemaker necessary. But if the electrical impulses disorganize, your heart may go too rapidly and require an implantable defibrillator. Pacemakers are implantable devices that consist of:.

Defibrillators rescue the heart from a rapid and confused heart rhythm which is usually fatal. Some people need help with both problems. These ventricular arrhythmias can occur without warning and are often fatal. Defibrillators can help:. But most defibrillators also have pacemaker abilities. That means this system is a fit for patients whose intrinsic heart rhythm is normal but who just have a block between the upper and lower chambers. Cunnane: This style of device is going to be the way forward as we imagine the future of cardiac implantable devices.

The next iteration of the new Micra AV will likely be a dual chamber leadless device that can pace for both the upper and lower chambers. That would be a new option for patients with both AV block and bradycardia, or too slow of a heart rate. If we can move to a more modular system, we could one day add or subtract components as patients need changes over time. Disclosure: Cunnane has advised companies including Medtronic, Inc.

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. The doctor will give a local anesthetic to numb the skin and tissue at the site of the pacemaker implantation.

After the area is numb, the doctor will guide the leads through the vein and into the heart's right-side chambers using fluoroscopy X-ray monitors. 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. We suggest that you wear a Medic Alert Emblem. Please ask for the form if you have not been given one.

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. Information on this site should not be used as a substitute for talking with your doctor.
