We provide pacemaker implantation and follow-up to give your heart a little help and keep you living life to the fullest.
Sometimes your heart needs a little help. In those situations, implantable devices offer life-improving – and life-saving – options. Over the next three days, we’ll take a close look at the three most common types of cardiac devices, what they do, and how they are implanted. We begin with pacemakers.
What is a pacemaker?
A pacemaker is a small, battery-powered device placed in the chest to keep the heart from beating too slowly. It constantly monitors the heart rate and rhythm and only works when it is needed.
Why would someone need a pacemaker?
Your cardiologist may recommend a pacemaker if you have certain types of slow heart rhythms such as sick sinus syndrome or complete heart block, or if you require medications for another condition, such as atrial fibrillation, that make your heart beat too slowly.
How does it help me?
When your heart beats too slowly (generally less than 60 beats per minute), your body’s cells may not get enough oxygen. This can cause problems like fatigue, easy tiring, lightheadedness, fainting (syncope), shortness of breath, chest pain, even confusion and memory problems. Your pacemaker speeds your heart up to resolve this issues. Note that athletes may have slower heart rates with no problems.
What is the procedure like?
We perform pacemaker insertions in the Cardiac Cath Lab at St. Mary’s Hospital and in the surgical suite at St. Mary’s Good Samaritan Hospital. Most patients need only moderate sedation but some may undergo general anesthesia. The left upper chest area is numbed and a small incision is made. A wire (or multiple wires, depending on your condition) is placed into the heart in specific areas. High resolution imaging is used to ensure proper placement. Those wires, or leads, are then connected to the device, which is placed under the skin and the incision is closed. Complications are rare; your cardiologist will talk with you about them before the procedure. You can expect to go home after a few hours in our recovery room.
What should I do after the procedure?
After the procedure, you cannot drive or shower for one week. For one month, you should not lift your left arm (the same side as the device) straight up. For most patients, there are no restrictions after the first month. If you are frequently around large machinery, engines, or arc welding, you should let your cardiologist know before the procedure. Monitor the site for signs of infection such as redness or pus. Follow up regularly with your cardiologist and device specialist to monitor the device. Also, if you ever need an MRI, be sure the doctor and technologist know you have a cardiac device.
How long does the battery last?
The battery typically lasts 5-10 years. Battery life is monitored and when it is time to change the battery, it is done with a minor outpatient procedure.
Are there different types of pacemakers?
Yes. There is a new type of “leadless” pacemaker called the Micra that implants directly inside your heart and does not need wires. Battery life is 8-13 years. Micra is a good choice for patients who only need pacing from the bottom chamber of the heart, may not be able to comply with arm lifting restrictions, or who may not want a visible scar on their chest. Your cardiologist will help you decide if Micra is right for you.
