Implantable Cardioverter Defibrillator (Definition)

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 ...Read more

Is an implantable cardioverter defibrillator removed in heart bypass surgery?

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

Are implantable cardioverter defibrillators safe? Effective?

Are implantable cardioverter defibrillators safe? Effective?

Yes and yes: While there have been specific manufacturer recalls of various leads and devices, overall implantable cardiac defibrillators are among some of the safest medical devices implanted. They are extraordinarily effective at terminating the potentially fatal heart rhythms they are implanted to treat. ...Read more

What is an implantable cardioverter defibrillator?

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

How does an implantable cardioverter defibrillator function?

How does an implantable cardioverter defibrillator function?

Detection: It detects fast heart beats above a threshold set by the cardiologist and programmed into the defibrillator and delivers a shock or atp - pacemaker override, depending on the heart rate. It will deliver subsequent shocks depending on the heart rate it detects. ...Read more

I can't decide: implantable cardioverter defibrillator or heart bypass surgery?

I can't decide: implantable cardioverter defibrillator or heart bypass surgery?

Different things: Bypass surgery (CABG) treats the blockages in the heart vessels, while the defibrillator (icd) treats dangerous heart beats such as ventricular tachycardia or fibrillation. A person may need both, depending on their medical condition. ...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

Can I play laser tag with an implantable cardioverter defibrillator?

Can I play laser tag with an implantable cardioverter defibrillator?

Yes: There would be no interference with your device from a laser. Also it's good exercise! talk to your doctor to be sure it's ok to get your heart rate up and to help you avoid inappropriate shocks by confirming your device programming. ...Read more

Is it common to remove an implantable cardioverter defibrillator during heart bypass surgery?

Is it common to remove an implantable cardioverter defibrillator during heart bypass surgery?

No: It was put in for a reason so unless something has changed, it will ordinarily be left in place unless the battery is failing, in which case it would be replaced. ...Read more

What can be done for implantable cardioverter defibrillator versus heart bypass surgery?

What can be done for implantable cardioverter defibrillator versus heart bypass surgery?

Different indication: Aicd for arrhythmias and ventricular tachycardia and does not revascularize. Bypass for coronary blockage (which can have arrhythmias) to improve circulation and sometimes stops arrhythmias induced by ischemia- low flow. ...Read more

What things interfere with pacemakers and implantable defibrillators?

What things interfere with pacemakers and implantable defibrillators?

Not much: Common household appliances and cellular phones are generally safe to use near an implantable defibrillator. It is best to avoid sources of significant electric current. For example, you should keep your icd 2 feet from an arc welder. You should not lean over your car engine while it is running. It is best to also keep large magnets off your device as well since this can affect its performance. ...Read more

How does bystander lightning (not a direct strike) affect implanted pacemakers, defibrillators, vagus nerve stimulators, etc...?

How does bystander lightning (not a direct strike) affect implanted pacemakers, defibrillators, vagus nerve stimulators, etc...?

Usually no effect.: The lightning strike (even as a bystander - it travels through the soil & can pop up at distances far from the original strike) can have deleterious effects on your heart (causing arrhythmia) or brain (causing unconsciousness) but these are just as likely with or without an implanted device. All electronic implants have a floating ground, which means they cannot short out because of an external ch ...Read more

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. ...Read more

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

New Guidelines: 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%, newyork heartassoc, 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

Would a pacemaker repair atrial fibrillation?

Would a pacemaker repair atrial fibrillation?

Not directly.: Pacemakers might be implanted as part of a care plan for af - but this only prevents slow pulses that might come as a result of medications for the af or after av-node ablation. Pacemakers themselves can not prevent or control af. ...Read more

What can interfere with pacemakers and implantable defibrillators?

What  can interfere with pacemakers and implantable defibrillators?

Pacemakers: Strong magnetic fields such as those used in security metal detectors and magnetic fields produced by large electric motors can interfere with pacemaker and defibrillator function. They may not necessarily turn a device "off" but can interfere with its programming. With only rare exceptions, patients with these devices need to avoid MRI scanners. Patients with these devices can have ct scans. ...Read more

Implantable defibrillator, is it forever?

Depends : The life of the device is several years. Depending on the reason it was placed and condition of the patient at the end of device life, in some individuals the device may not be exchanged. In most though, the device will remain in place and will be exchanged once battery reaches end of its life. ...Read more
