When is an implantable cardioverter defibrillator used to treat patients with arrhythmias?

Sudden cardiac death. Icd's are utilized in patients who are at risk for sudden cardiac death or ventricular arrhythmias. These can be patients who already have significant structural heart disease or may have already suffered a sudden death episode. Also they are utilized in patient's who have certain familial conditions which may predispose them to sudden death.
It depends. When the risk for cardiac arrest is high enough, a physician may recommend a patient get an icd. This might be for patients with a weak heart, genetic disease (like hocm, long qt, arvd), or someone who has survived a cardiac arrest already.

What patients need an implantable cardioverter defibrillator?

Ventricular Arrhythm. Patients that have dangerous arrhythmias such as ventricular tachycardia or ventricular fibrillation are the usual candidates for an implanted cardio-verter defibrillator or icd. Read more...
VT/VF, certain other. In addition to preventing dangerous ventricular arrhythmias (which can cause sudden cardiac death) in people who have had these, in certain select cases cardioverter defibrillators have use for prevention of these heart rhythms in people who are at high risk for them. This can include certain cardiomyopathies, also some cases of congestive heart failure (combined with a biventricular pacemaker). Read more...

What patient aftercare is required for implantable cardioverter-defibrillator?

Office and hospital. Initial postimplantation care centers on wound healing. Subsequent followup relates to monitoring the function of the device. Regular office visits are required to assure that the device is functioning normally. As the devices can be life saving, close attention is paid to battery life so that the device can be replaced before the battery fails. Read more...

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

Prevent recurrence. Depending on the reason for cardiac arrest, an automatic implantable defibrillator can be very effective in preventing a second cardiac arrest in the future. Read more...
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...

Arrhythmias. An implantable cardioverter defibrillator (icd) is primarily used to treat abnormally rapid heart rates that are considered to be life threatening. The most common of these conditions are ventricular tachycardia and ventricular fibrillation. These devices can also act as pacemakers to treat low heart rates, but this is a secondary function.

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...
Yes. Aicd can detect rapid heart beat and stop the cardiac arrhythmias by either overdrive pacing or delivering the shock. It is programmed at certain zone of heart rate. For exemple if it is programmed at 180 beats the device will deliver the treatment at at heart rate of above 180. Read more...

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...
ICD. Icds are implanted to monitor the electrical activity of very abnormal hearts to see if a life threatening rhythm occurs. If it detects one of these rhythms, it will charge its capacitor and fire a shock to defibrillate the heart back to stable rhythm. In appropriate patients these devices save lives. Read more...

Is an implantable cardioverter defibrillator removed in heart bypass surgery?

No. The defib. Device is implatnted in the inner chambers of the heart and bypass is on the out side of the heart where the coronary arteries lie.Unless theres another reason to remove the device ie an infection the device is left in. Read more...
