This device senses when your heart is beating irregularly or too slowly. It sends a signal to your heart that makes your heart beat at the correct pace. A pacemaker is implanted under the skin. This procedure takes about 1 hour in most cases. You will be given a sedative to help you relax.
You will be awake during the procedure. A small incision cut is made. Most often, the cut is on the left side if you are right handed of the chest below your collarbone. The pacemaker generator is then placed under the skin at this location. The generator may also be placed in the abdomen, but this is less common.
A new "leadless" pacemaker is a self-contained unit that is implanted in the right ventricle of the heart. Using live x-rays to see the area, the doctor puts the leads through the cut, into a vein, and then into the heart. The leads are connected to the generator. The skin is closed with stitches.
Most people go home within 1 day of the procedure. Pacemakers may be used for people who have heart problems that cause their heart to beat too slowly. A slow heartbeat is called bradycardia. Two common problems that cause a slow heartbeat are sinus node disease and heart block. Some pacemakers can be used to stop a heart rate that is too fast tachycardia or that is irregular. Other types of pacemakers can be used in severe heart failure.
These are called biventricular pacemakers. They help coordinate the beating of the heart chambers. Most biventricular pacemakers implanted today can also work as implantable cardioverter defibrillators ICD.
ICD restore a normal heartbeat by delivering a larger shock when a potentially deadly fast heart rhythm occurs. A pacemaker senses if the heartbeat is above a certain rate.
When it is above that rate, the pacemaker will stop sending signals to the heart. Your doctor may recommend this device to keep your heartbeat from slowing down to a dangerously low rate. The heart is a pump made up of muscle.
The muscle is stimulated by electrical signals. These signals normally follow a specific circuit within the heart. These signals organize contractions of the different parts of the heart. This makes it beat at a rate that keeps blood flowing around the body the way it should.
A pacemaker may be needed when there are problems with the electrical signals in the heart. Your heart may sometimes beat too slowly, or at an irregular rate. A pacemaker is made of 3 parts.
They include a pulse generator, 1 or more leads, and an electrode on each lead. A pacemaker signals the heart to beat when the natural heartbeat is too slow or irregular. Your healthcare provider may advise a pacemaker when your heart beats too slowly and this can't be fixed with other treatments. A pacemaker will cause a faster heart rate. Problems with the heart rhythm may mean your heart is not pumping enough blood to the body.
If your heart rate is too slow, the blood is pumped too slowly. If the heart rate is too fast or too irregular, the heart chambers are unable to fill up with enough blood to pump out with each beat. Medicines are often used to slow down these fast heart rhythms. But the medicines can also result in slow heart rates when the rhythm is normal. When the body does not get enough blood, symptoms such as tiredness, dizziness, fainting, or chest pain may occur.
Tachy-brady syndrome. This is characterized by alternating fast and slow heartbeats. Heart block. This occurs when the electrical signal is delayed or blocked as it travels through the heart muscle. There are several types of heart blocks.
Bleeding that can occur from the heart with blood accumulating in the sac pericardium surrounding the heart pericardial effusion. Lead displacement. This means the wires of leads of the pacemaker become disconnected or displaced. You may need another procedure to reposition them. For some people, having to lie still on the procedure table for the length of the procedure may cause some discomfort or pain. There may be other risks. This depends on your specific health condition.
Be sure to discuss any concerns with your healthcare provider before the procedure. Your healthcare provider will explain the procedure to you and ask if you have any questions. You will be asked to sign a consent form. This gives your permission to do the procedure. Read the form carefully. Ask questions if anything is not clear. Tell your healthcare provider if you are sensitive to or are allergic to any medicines, iodine, latex, tape, or anesthetic agents local and general.
You will need to fast not eat or drink for a certain period before the procedure. Your healthcare provider will tell you how long to fast, usually overnight or at least 8 hours before the procedure.
Tell your healthcare provider if you are pregnant or think you might be, or if you are breastfeeding. Be sure your healthcare provider knows about all medicines, vitamins, herbs, and supplements that you are taking.
This includes both prescription and over-the-counter medicines. Tell your healthcare provider if you have a history of bleeding disorders or if you are taking any anticoagulant blood-thinning medicines. This includes aspirin, or other medicines that affect blood clotting. You may need to stop taking some of these medicines before the procedure. Tell your healthcare provider if you have heart valve disease. You may need to take antibiotics before the procedure.
You may get a sedative before the procedure. This is to help you relax. If a sedative is used and you go home right afterward, plan to have someone to drive you home. You will likely spend at least 1 night in the hospital after the procedure. This is to watch your heart and make sure the pacemaker is working the way it should. Based on your health condition, your healthcare provider may request other specific preparation.
A pacemaker insertion may be done on an outpatient basis. Or it may be done as part of your hospital stay. The procedure may vary depending on your health and how your healthcare provider does the procedure. You will be asked to remove your clothing and will be given a medical gown to wear. An IV intravenous line will be started in your hand or arm before the procedure.
This is to give you medicine and fluids. You will be connected to an electrocardiogram ECG monitor. This records the electrical activity of your heart. It monitors your heart during the procedure using small, plastic electrodes that stick to your skin. Your vital signs will also be watched during the procedure.
