![]() ![]() Ask your health care team what machines or equipment you should avoid. The longer you’re exposed to the potentially interruptive device and the closer it is to your ICD, the more likely it will affect your ICD’s performance. If you have an ICD, be aware of your surroundings and the devices, such as those with strong magnetic fields, that may interfere with its operation. What should I ask my doctor or nurse about living with an ICD? Stored information can help your doctor optimize the ICD for your needs. They also offer other functions such as storage of detected arrhythmic events. Some devices also provide “overdrive” pacing to electrically convert a sustained ventricular tachycardia (fast heart rhythm) and "backup" pacing if bradycardia (slow heart rhythm) occurs. When your heartbeat is too fast or chaotic, it gives defibrillation shocks to stop the abnormal rhythm.If your ICD has a pacemaker feature when your heartbeat is too slow, it works as a pacemaker and sends tiny electric signals to your heart.It detects an abnormal heartbeat and tries to return the heartbeat to normal. ![]() Wires or leads run from the pulse generator to positions on the surface of or inside the heart and can be installed through blood vessels, eliminating the need for open-chest surgery. The generator is about the size of a pocket watch. In infants, it may be placed in the abdomen. A congenital heart disease or other underlying conditions for sudden cardiac arrestĪ battery-powered pulse generator is implanted in a pouch under the skin of the chest, often just below the collarbone, or along your ribs.Your health care team may recommend an ICD if you or your child is at risk of a life-threatening ventricular arrhythmia because of having: Electrolyte imbalance and drug toxicity.Myocardial ischemia (inadequate blood flow to the heart muscle).Acute myocardial infarction ( heart attack).It detects arrhythmias and responds with electrical signals to restore your heart's normal rhythm.Ī person is a candidate for an ICD if they have a life-threatening arrhythmia without correctable causes, such as the following: If an abnormal heart rhythm is detected the device will deliver an electric shock to restore a normal heartbeat.Īn ICD is implanted under the skin, just under the collarbone. Thin wires connect the ICD to your heart. What is an Implantable Cardioverter Defibrillator?Īn ICD is a battery-powered device placed under the skin that keeps track of your heart rate. Most ICDs, called transvenous ICDs, have a dual function and also serve as a pacemaker. ![]() These include ventricular tachycardia (VT) or ventricular fibrillation (VF). ICDs are useful in preventing sudden death in people who have a high risk of a life-threatening arrhythmia.
