Please inform me, is the dual chamber pacemaker is contraindication with atrial fibrilation? What the best pacemaker for AF people? Better ICD or PPM?

Please inform me, is the dual chamber pacemaker is contraindication with atrial fibrilation? What the best pacemaker for AF people? Better ICD or PPM?

Depends on AF??: Ask your doctor what kind of atrial fibrillation you have. If dealing with paroxysmal atrial fib. and your doctor recommended pacemaker then dual chamber pacemaker is better suitable for you. If dealing with persistent or chronic AF and you have indication for pacemaker then single chamber pacemaker. Also discuss the current medication regimen with your doctor as some medication can affect rhythm ...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

Beside taking arrhythmia medicines, what are other option for atrial fibrillation? Does a pace maker or defibrillator cure a fib?

Beside taking arrhythmia medicines, what are other option for atrial fibrillation?  Does a pace maker or defibrillator cure a fib?

Ablation: Catheter ablation (pulmonary vein isolation) can be curative. Although not curative, an av node ablation in combination with a pacemaker or defibrillator can usually eliminate the symptoms of atrial fibrillation. If you have obstructive sleep apnea using CPAP can greatly improve atrial fibrillation. ...Read more

I'm in Afib n atrial flutter. can i do some physical exercise? what is the best exercise for patient Afib n Atrial flutter like me?? thank you

Exercise is good for: You must exercise; it is not harmful to your heart rhythm. But do it with moderate pace like a brisk walk for one to two miles daily(start slowly and build it up). Avoid heavy duty weight lifting etc. Good luck ...Read more

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

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

For Atrial Fibrillation, can you still have an electrical cardio-version if drugs (Flecainide) stop working?

For Atrial Fibrillation, can you still have an electrical cardio-version if drugs (Flecainide) stop working?

Yes: Please make sure you have seen an electrophysiologist... That is really essential... In short yes you can be cardioverted, but by a specialist ...Read more

I need to undergo cardiac ablation to treat my atrial fibrillation, how do I select a doctor?

Eectrophysiologist: I agree that an electrophysiologist wil provide the best information regarding catheter ablation. It is important to ask questions regarding outcomes and success rates. I would recommend a university setting for this type of ablation that will provide the best staff as well as equipment. ...Read more

Please explain how a pacemaker does/does not control atrial fib. Also, other than heart cath, how can plaque be detected? Thanks these questions are in regards to my father's health. He has a pacemaker to control low heart rate, but pacemaker output has

Yes, : Yes, there are other options for treating atrial fibrillation as well as other diagnostic tests that can be performed to detect clots int the heart. Atrial fibrillation is an arrythmia where the person is a high risk for developing clots within the heart because the heart is unable to effectively pump blood to the body, leading to pooling of blood in the heart. Atrial fibrillation can be treated with medication or ablation, which work to get the heart's primary pacemaker to resume function. Another procedure that can be done is cardioversion. In a cardioversion, an electric shock is delivered to the heart to 'shock' the heart back to the person's normal rhythm. This procedure can be done for a person with a pacemaker, however the doctor must take measures to ensure no damage to the device. There are imaging tests, such as an echocardiogram, that can help a physician to determine the presence of clots in your heart. Echocardiography uses sound waves to create pictures of your heart. This test can detect areas of the heart where blood is not flowing properly, indicating a possible clot or blockage. Also, this test is useful for identifying parts of the heart that are not contracting well. ...Read more

Can you tell me if atrial fibrillation with ventricular standstill is recognized from fine v-fib?

Can you tell me if atrial fibrillation with ventricular standstill is recognized from fine v-fib?

Afib/vfib: ventricular standstill and fine v-fib are functionally the same the ventricle is not contracting - vfib is a slight quivering which may or may not be identifiable on ECG; if the ventricle is not contracting then it is not possible to non-invasively identify atrial fibrillation from simply sinus/atrial arrest. ...Read more

Can I have Atrial Flutter (AF) while wearing a pacemaker for complete heart block? Do I need ablation or it managable by using medication?

Can I have Atrial Flutter (AF) while wearing a pacemaker for complete heart block? Do I need ablation or it managable by using medication?

Complex question: Your best off using HealthTap Prime to ask this question, since it's complex & answer is nuanced. The only problem, as I see it, is that with ongoing AF, you can develop clots (thombus) that can dislodge & cause a stroke. Your heart RATE should be controlled by the pacemaker, so the only adverse effect of AF would be a stroke. This can be mitigated by anticoagulants (blood thinners). Use HT Prime. ...Read more

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

I have a-fib, v-tach, and angina why would tikosyn (dofetilide) be prefrable to flecanide?

Depends on the prob: Treatment of heart rhythm problems can be very complicated. Flecainide is contraindicated in patients with hx of heart attack (increased mortality) and chronic atrial fibrillation (excessive rhythm problems). ...Read more

What does someone implant to control atrial fibrillation?

What does someone implant to control atrial fibrillation?

Not much.: In reality, there are no implants that are commonly used to control atrial fibrillation. There used to be atrial defibrillators, but these are not used much any more. 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 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

What drug is superior pradaxa or warfarin? I have two metal bare stents and a history of atrial defibrillation.

Depends: Both are anticoagulants, and are used for prophylaxis in atrial fibrillation. Bare metal stents are better treated with Aspirin and plavix (clopidogrel). Between Pradaxa and warfarin, both are effective, with Pradaxa requiring no monitoring, but warfarin much less expensive. ...Read more
