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

Pacemaker (Definition)

A pacemaker is a device which sends electrical signals to the heart triggering heartbeats when needed. There are many ways to implant and configure a pacemaker; it may beat the top chambers (atria), lower chambers (ventricles) or both. Some systems stimulate both the left and right ventricles together. Pacemakers generally treat abnormally slow heart rhythms and certain ...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

What are fixed rate pacemaker and demand type pacemaker?

What are fixed rate pacemaker and demand type pacemaker?

Pacemakers: Fixed rate pacemakers stimulate the heart to beat all the time at a specified rate. Demand pacemakers only pace the heart if the rate falls below a certain set rate or irregularity in heartbeat occurs. ...Read more

How do pacemakers and defibrillators work?

How do pacemakers and defibrillators work?

Heart Rhythm: Pacemakers control the rate of the heart's beat. Defibrillators deliver shock(s) to try to return the heart to a normal rhythm. ...Read more

Do defibrillators work in asystole?

Do defibrillators work in asystole?

No: Defibrillators work to disrupt an irregular, rapid, pathological heart beat. They don't "jump start" a heart that is not beating. ...Read more

Are pacemakers and waterbeds compatible?

Are pacemakers and waterbeds compatible?

Yes: A permanent pacemaker is implanted inside a person, and the pacemaker does not know whether or not a person is on a waterbed. Pacemaker patients do not have to worry about using normally functioning common household appliances such as microwave ovens, televisions, radios, toasters, electric blankets, modern cell phones, and modern portable media players... according to UpToDate's patient brochure. ...Read more

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

Can pacemaker fix all cases of atrial fibrillations?

Can pacemaker fix all cases of atrial fibrillations?

No: Atrial fibrillation is an irregular heartbeat of the upper chambers of the heart. Its greatest danger is the formation of bloodclots within the heart which can trravel up to the brain and cause a stroke. Patients with af are generally treated with anticoagulants or blood thinners like aspirin, warfarin (coumadin) or dabigatran (pradaxa) to prevent strokes and medication to control the heart rate. ...Read more

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

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

How are cardioversion and defibrillation different?

How are cardioversion and defibrillation different?

Cardioversion: We use electrical cardioversion to convert tachyarrhythmias to normal rhythm when appropriate. When the rhythm we are shocking is atrial or ventricular fibrillation, we call the cardioversion defibrillation. ...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

How are pacemakers placed?

How are pacemakers placed?

Minor surgical proce: Pacemakers are placed in a cardiac cath or surgical suite with the visual guidance of fluoroscopy (x-ray visualization). A pacing lead is placed into the heart after access to a vein in the arm, groin, neck, chest is obtained. Specific electrical parameters of the lead are checked, then the lead attached to a pacemaker often embedded in the upper chest wall, where small incision is made. ...Read more

Can you defibrillate any patient in ventricular tachycardia?

Dr. Jesus Yap Dr. Yap
1 doctor agreed:

Yes : Yes but only when the tachycardia is fast and not tolerated . But the electric current has to be synchronized with the heart beat.This is most appropriately called cardioversion than defibrillation the latter being unsynchronized electric shock for ventricular fibrillation which is a chaotic ineffective rhythm. ...Read more

When are pacemakers necessary?

HeartRhythm or block: Pacemakers are most commonly necessary for patients with bradycardia- slow heart rate, tachycardia - fast heart rate, and heart block - when the heart stops beating for several seconds. ...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

Timeframe between heart failure and defibrillation?

Timeframe between heart failure and defibrillation?

May not happen: Heart failure generally refers to dysfunction in the pumping action of the heart (various types exist). Defibrillation is basically an electric shock designed to "reset/restart" the conduction system of the heart (during an arrhythmia). Heart failure increases risk of arrhythmia, but doesn't guarantee it will happen. Live healthy, follow tx & doctor's recc's , and hopefully it won't happen. ...Read more
