Atrial Fibrillation With Aberrant Conduction
Atrial fibrillation: Atrial fibrillation, or afib, is a very common rhythm disturbance, the most common in this country. It is most often associated with hypertension, but can also be associated with valvular disease specifically mitral valve disease. It can be treated with either rate control or converting back to the normal sinus rhythm. Patient are often placed on blood thinners to prevent complications.See 1 more doctor answer
Read...: As per epocrates: CAD (coronary disease) hypertension, heart failure, valvular disease, pericardial and pleural diseases, diabetes, thyroid disorders, disorders of the lung, and advanced age are known risk factors for the development of acute af. However, af may occur in the absence of any underlying cardiac or noncardiac diseases, for example, as a result of heavy alcohol intake.See 2 more doctor answers
Depends: New onset atrial fibrillation is often self limited, going away by itself. But the cause dictates the subsequent course. Thus treating things like high blood pressure, heart valve disease, heart failure, over active thyroid hormones, coronary disease, and avoiding alcohol may be important. Some drugs are useful to maintain rate and rhythm. If needed, electric shock (cardioversion) is effective.See 2 more doctor answers
Depends: Atrial fibrillation is a very common arrhythmia, often unclear in origin, but usually due to enlarged upper heart chambers (atria). High blood pressure, heart valve problems, heart failure, hyperthyroidism, coronary disease, alcohol, or even spontaneous in normal people. Some drop in energy may be noted, but one can live normally with it. Blood thinners to minimize strokes important if persists.See 2 more doctor answers
Atrial fibrillation: Flying in a commercial aircraft pressurizes to about 8000ft, this level doesn't cause hypoxia so unlikely to be a trigger unless something else like anxiety or other stress supervenes. If something goes on stressful in the aircraft, one could imagine a trigger possibility. I have seen patients get a gas bubble in their GI tract at altitude and be anxious for instance.See 1 more doctor answer
Atrial fibrillation: We have a variety of medications we use for afib. First we need to diagnose that its there and why before we choose medications. We have anticoagulants, rate control medications and rhythm modulating medications. There are multiple choices for each with advantages and disadvantages to each. There is no one 'best', we choose depending on the patient's status and individualize for each.
Rate or rhythm?: Some meds are good to control the heart rate in af, others are to try to control the rhythm and maintain normal sinus rhythm. In addition, blood thinners (anticoagulant meds) need to be considered for some people. So, there is not an easy answer. If this applies to you and you are only 40, you should also consider a curative ablation procedure.
Define cured: Atrial fibrillation is a degenerative disease of the upper chamber which results in deposition of microscopic amounts of scar tissue, a generally irreversible process. However, certain procedures such as a surgical maze or catheter ablation can prevent patients from developing the rhythm of atrial fibrillation, or, barring that, the symptoms from the arrhythmia with up to ~70% success.See 1 more doctor answer
Cardiologist: You should really see a cardiologist who can go over all of the options with you and well as work out any possible underlying causes such as elevated thyroid. You need to carefully discuss whether it is best to try and keep you out of afib with a procedure or medications or not. This is a long discussion that needs to be tailored to the individual.See 1 more doctor answer
Lots of choices: If the goal is just to control the heart rate, the common choices are drugs that slow the heart rate like a beta blocker or calcium channel blocker and a blood thinner to lower the risk of stroke. Classically coumadin, (warfarin) but there are newer ones (xarelto, for example). Sometimes there are drugs given after the heart has been restored to a normal rhythm that help maintain this, such as amiodarone.
Sometimes: Af tends to progress over time in the majority of patients, but this progression is slow, often over years or even decades. Uncontrolled hypertension, other heart diseases, obstructive sleep apnea etc. Can accelerate this process. Treatment of af with medications (antiarrhythmic drugs), and treatment of the predisposing conditions, often slows or prevents progression.
Atrial Fibrillation: Atrial fibrillation is a condition where the atria of the heart no longer have an organized electrical activity and hence do no longer fulfill their pumping function properly. The typical ECG finding is for an irregularly irregular rhythm with absence of p-waves.See 1 more doctor answer
