Implantable Cardioverter Defibrillator (Overview)

An implantable cardioverter defibrillator, or icd, is a small device that can automatically detect abnormally fast heart rhythms and stop them with a rapid pulse of paced beats or a shock. It monitors the heart rate and delivers the treatment through special wires, or leads, that may be attached to the inside or outside of the heart or placed under the skin. Most icds also have pacemaker function.

What is an implantable cardioverter defibrillator?

Life saver: An implantable cardioverter defibrillator (icd) system has leads (wires) that are inserted through the veins under the collarbone and threaded to the heart. The leads are attached to a box that goes under the skin. The box has a computer that continuously monitors the signals from your heart for a dangerous arrhythmia. If this occurs, the icd stops the arrhythmia by delivering an internal shock. ...Read more

What benefit does the implantable cardioverter-defibrillator give to patients who have had a cardiac arrest or heart attack?

What benefit does the implantable cardioverter-defibrillator give to patients who have had a cardiac arrest or heart attack?

It may prevent death: Implantable cardioverter-defibrillators (icds) are used to treat ventricular tachycardia or ventricular fibrillation, which if untreated, may cause a fatal cardiac arrest. Icds can often quickly treat these conditions before permanent brain or heart damage can be done. Icds are not used to treat or prevent heart attacks, which are a "plumbing" issue. ...Read more

How do you relieve pain from implantable cardioverter defibrillator surgery?

Pain and AICD: Post-operative pain is normal but should not be excessive. First, what is the cause of the pain? If the surgical site is red, swollen, or oozing fluid, contact the implanting physician immediately. The problem could be serious. ...Read more

How does an implantable cardioverter defibrillator function?

How does an implantable cardioverter defibrillator function?

Defibrillators: The device has an antenna that monitors the electrical activity of the heart. If the recorded parameters fit those of ventricular tachycardia or ventricular fibrillation, the device will charge its capacitor and deliver programmed shocks to try and return the rhythm to normal. It is a computer and programmed to do its functions. They are very effective but not perfect. ...Read more

Is an implantable cardioverter defibrillator usually efficient?

Yes: Implanted cardioverter defibrillators (icds) are the most effective treatment in terminating dangerous arrhythmias. Icds are not 100% effective, but are significantly better than medication alone. ...Read more

What is the function of an implantable cardioverter-defibrillator?

What is the function of an implantable cardioverter-defibrillator?

Terminate arrhythmia: These are devices which may detect and automatically treat malignant (life-threatening) arrhythmias. Those include ventricular tachycardia and ventricular fibrillation. They use either bursts of rapid pacing or one or more high energy shocks. Patients receive these either after an arrhythmic event or prophylactically because they are at risk for these arrhythmias. ...Read more

Defibrillator (Definition)

Defibrillation is a common treatment for life-threatening cardiac dysrhythmias, ventricular fibrillation, and pulseless ventricular tachycardia. Defibrillation consists of delivering a therapeutic dose of electrical energy to the affected heart with a ...Read more
