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.
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).

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...

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

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. Read more...
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. Read more...

What patients should get an implantable cardioverter-defibrillator (icd) for heart failure?

See Below. This is somewhat complex and will not all fit in 400 characters so I am creating initials. 1. Ischemic cardiomyopathy, i.C., with ejection fraction, ef, >30% but <35%, newyorkheartassoc, nyha, class ii or iii, and >30 days post mi/revascularization. 2. Ic, ef <30%. 3. Ic, ef between 36-40% with inducible ventricular fibrillation or tachycardia, 4. Non-ic with ef <35% and nyha class ii or greater. 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...

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...

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...
Tylenol (acetaminophen) It will improve over time- it is uncomfortable because it is quite a large device under the skin, but your body will get use to it. Until then just tylenol, (acetaminophen) and perhaps advil if you can tolerate it. Good luck. Read more...

What are the risks are associated with an implantable cardioverter-defibrillator?

AICD. First of, this is a life saving device for individuals needing one! as this is inserted using surgical techniques, risks associated are bleeding, infection etc... Once implanted the device or leads can malfunction or administer an inappropriate shock etc.. Bottom line: very high benefit (stay alive), low risk. Read more...
Tiny risk. An icd is indicated for people who are judged to be at significant risk for sudden cardiac death. Not implanting an icd in this context confers a far higher risk than the procedure which, itself, is a relatively simple and low risk minor operation done with sedation and local anesthetic. There are small risks of bleeding, blood clot and infection. Read more...

What is the morbidity rate for people with an implantable cardioverter-defibrillator?

Short vs Long Term. Device insertion is very safe, with estimated 2% risk of complications (bleeding, infection). Depending on the person's age and health status, they may have the defibrillator for many years. There is a low risk of infection of device in future (rough estimates of this are single digit to 10%), and risk of getting inappropriate shocks from the device (causing anxiety) is in this rough range as well. Read more...
Minimal. About 1% or less -- the morbidity is more from the heart disease and others but not from having an icd implanted. Read more...

What precautions should be taken in prescribing an implantable cardioverter-defibrillator?

AICD. An aicd is recommended for very specific conditions and following very specific and well documented indications as published by professional societies (american college of cardiology, american heart association, european society of cardiology etc...) any prescription/recommendation has to follow these indications.
