Does radiation therapy cause atrial fibrillation - Doctor answers
Which drugs are mostly recomended to start therapy for patients with atrial fibrillation. Is quinidine a good chioce?
Atrial fibrillation: Quinidine is only rarely used any more. We older doctors learned years ago that we killed some folks with it. There are more recent and safer drugs that we use now. Talk to your doctor to discuss if you have afib, a cloud doctor shouldn't be advising you without knowing your situation. ...Read more
Atrial fibrillation: Afib is a rapid irregular heart rhythm which can decrease heart efficiency as much as 20% in some patients. It can also be associated with clotting and clots travelling around the body to cause stroke or other problems. Some people have atrial fibrillation as their normal rhythm. We use drugs to control rate, rhythm and if not successful, ablation therapy by electrophysiologist. ...Read more
Yes: All catheter-based techniques are considered minimally invasive. Conventional techniques are up to 75% effective though multiple procedures are frequently required. There is a mini-thoracotomy procedure they can do with slightly improved efficacy over this but it involves making a lot of scar tissue around the left atrium; we usually reserve that for people needing other procedures in the chest. ...Read moreSee 1 more doctor answer
Depends: It depends on how many other diseases you have. For the people with the highest risk, it can cause strokes, which can be deadly. Anyone with this condition needs to see a Cardiologist. ...Read more
Yes: Vagal-mediated atrial fibrillation typically occurs at night while people are sleeping or may occur when drinking something cold or going to the bathroom. An antiarrhythmic called norpace, or disopyramide, works well in this situation, as it has anti-vagal properties. ...Read moreSee 1 more doctor answer
Taking 200 mg of Flecainide daily and still having episodes of atrial Fibrillation and PVCs. What should the next course of treatment be? Thanks
Follow your MD lead: You need to be patient and stick to the treatment offered by your cardiologist or electro physiologist and discuss your options and doubts with them. Do NOT over read or look for answers on the internet. This can be harmful when the arrhythmia, in general, is not. ...Read more

What meds can I use to control my a fib? What are the risks and side effects of medications to control my atrial fibrillation or to reduce the risk of stroke? What are the risks/benefits of other treatment options?
The treatment of atrial fibrillation has two important components: 1) treating the rhythm, and 2) preventing stroke. There are two strategies for treating the rhythm. The first is called the rate control strategy, and involves using medicines to prevent the heart rate from going too fast. These medicines do not prevent atrial fibrillation episodes, but are generally effective at preventing fast rhythms and also tend to have few side effects. This is a good strategy for people who do not have severe symptoms from atrial fibrillation, such as older less active people. The second strategy is called the rhythm control strategy, and involves using medications that are designed to maintain normal sinus rhythm and prevent episodes of atrial fibrillation. This strategy may be more desirable for people who are vey symptomatic when in atrial fibrillation such as young, active people. Unfortunately, this strategy tends to be less successful because recurrence of atrial fibrillation is common. The rhythm control medications also tend to have more side effects than the rate control medicines, and in some cases the side effects can be severe. Neither strategy is better than the other at preventing stroke.
For stroke prevention, warfarin (also called coumadin) is typically used for people at moderate or high risk. This medication has been shown to be superior in preventing stroke, but it also increases the risk of dangerous bleeding because it is a blood thinner. Patients at lower risk for stroke may just take an Aspirin tablet daily. This has a lower bleeding risk than warfarin.
Lastly, some people are candidates for surgical or catheter-based ablation procedures. These procedures can cure atrial fibrillation, but are not always successful and not all people are good candidates. ...Read more
I have been to the ER for a rapid heartbeat. Sometimes it's diagnosed as sinus tachycardia and sometimes atrial fibrillation. I have tried cardyzeme and metopral without much success. What happens if I don't seek treatment next time?
I agree with dr. Guyton's excellent and thorough answer and would like to emphasize that with atrial fibrillation there are two main issues:
1) heart rate - a fast heart rate is typically what most people present with, and typically can be managed with medications to control heart rate such as the two you described, although there are others. Sustained high heart rates are not good for the heart, but as long as you are not having chest pain, shortness of breath, dizziness, or loss of consciousness then you can call your physician before rushing to the er.
2) stroke - afib presents a very real increase risk of stroke if not properly treated. For this reason, an accurate diagnosis is a must, and if it is indeed afib the you should discuss with your physician whether you are high enough risk to require blood thinners such as Coumadin (warfarin) or pradaxa. This is a long term risk so can be discussed in the outpatient setting with your docotor or a cardiologist. ...Read more
If atrial fibrillation with sick sinus syndrome changes from intermittent to continuous, is further treatment needed? Taking Coversyl & Pradaxa now.
AF: This discussion should be with your doctor who knows you and your entire situation. In general if maintaining sinus rhythm is no longer realistic, we still need to continue rate control and usually anticoagulation. These treatments however need to be patient specific. ...Read more
For young (<60), asymptomatic, paroxysmal atrial fibrillation patients on NOACs with LVH, should the patient seek out catheter ablation for treatment?
Depends: On left atrial size and function, frequency. Ablation is a big deal and frequently unsuccessful. I would try to suppress with a beta blocker like Bystolic, get magnesium level to 2.1-2.4, potassium to 4.1-4.5, stay off stimulants/alcohol, use hawthorne berry, avoid many other supplements, get general labs checked. Why the LVH? HRS, MD, FACC. Www. Thepmc. Org ...Read more
Why the atrial fibrillation causing thromboembolic phenomena while atrial flutter don't cause it?
Short answer: Atrial fib has increased risk secondary to irreg. Firing of atria and valves causing damage to blood cells. In flutter there is a more regular rate and atrial contractile function offers some protection but there is still a slightly increased risk. In chronic flutter, coagulation is necessary given the risk of stroke is the same as atrial fib. Pts with chronic flutter often have a fib as well. ...Read moreSee 2 more doctor answers
Improved Ablation: The techniques we use to ablate afib haven't changed much in the past 10 years or so, but there's a new technique we're just finishing the early trials on which may potentially be a game-changer. It should be on the market late this year and will probably start being widely available next year. ...Read moreSee 1 more doctor answer
In the right patient: An invasive procedure called an atrial fibrillation ablation using either radio frequency or a freezing technology called cryoablation actually has a relatively high rate of cure in carefully selected patients. I would recommend that you speak with a cardiologist who then can recommend the best electrophysiologist (a type of cardiologist) in your area for this procedure. ...Read moreSee 1 more doctor answer
What causes atrial fibrillation? Is stress the main cause of atrial fibrillation, and is it genetic?
Not Really: The main cause in ~90% of cases from young persons like you is extra heartbeats starting in structures called the pulmonary veins. Sometimes that's all it is; more often than not though, the top chambers (atria) also have dilation and scar tissue which helps sustain the fib once it starts. Only a small portion of afib is clearly known to be genetic. Stress triggers extra htbeats -? -> fib. ...Read moreSee 2 more doctor answers
No: Our best understandings of afib require that the heart muscle have undergone changes over a prolonged period of time to enable afib. While it's possible the stress of an accident could have "set off" an afib attack, if it sticks around, you were likely at risk in the first place. A truly severe wreck can bruise the heart, but the fib would pass as the bruise heals. ...Read moreSee 1 more doctor answer
