How does quinidine, procainamide, and disopyramide treat atrial fibrillation?

Variable. These medications are older antiarrythmics that have been around for decades and may suppress af. They must be used very cautiously and only by very experienced cardiologists, due to their potential to actually cause potentailly life threatening ventricular arrythmias in certain patients - called a pro-arrthymic effect..Newer medications have been shown to be both safer and more effective.
Slow conduction. These medications, known as class i antiarrhythmics, work by blocking sodium channel conduction in the heart. This causes cardiac excitation to progress more slowly, hopefully preventing the formation of the driving force behind atrial fibrillation.

(1) Is bisoprolol used to treat atrial fibrillation? (2) If a person becomes hypotensive e.g.102/55, 102/68, & 106/63 should he stop using bisoprolol?

Yes. This beta blocker is used to treat or control the ventricular response to atrial fibrillation. It can lower blood pressure and, of course, slow the ventricular rate too much(below 60). If you're experiencing side effects, discuss this with your physician or cardiologist who may lower the dose of prescribe another beta blocker or even switch to digoxin although this medication is less popular now.

How can atrial fibrillation and flutter be treated?

Meds and procedures. Medications are used to control the heart or restore normal rhythm. Depending on the risk factors, blood thinners may be prescribed to lower the risk of stroke. Catheter and surgical procedures are also available in some patients to restore sinus rhythm. Read more...
Similar. Both are atrial arrhythmias. They often occur in the same person, sometimes moments apart. In fib, the atrial electrical activity is completely disorganized. In flutter, the atrial rate is usually 300. In untreated fib, the ventricular rate is usually 160-200. In flutter, the vr is usually 150. Read more...
Three options. Generally speaking, we can attempt to control the rate, we can attempt to keep you in a normal rhythm with medications, or we can attempt a long-term tour of the rhythm using a catheter ablation. There are also surgical treatment for the arrhythmias, but these are generally not first-line treatments unless you have another reason to have heart surgery. Read more...

How is atrial fibrillation usually treated?

Slow down the heart. Beta blockers and digoxin are often used first to slow down the heart when there is rapid heart rate of af. In some patients, electric shocks can be utilized to convert the irregular rate of af to normal. In most all cases, blood thinners such as Coumadin (warfarin) and new drugs like Pradaxa are utilized to reduce the risk of blood clots forming inside the heart and causing complications such as strokes.

I understand that atrial fibrillation is a type of arrhythmia. Is ablation used to treat only afib or other arrhythmia conditions?

Many dysrhythmias. Ablation is a procedure used to treat many different types of dysrhythmias; atrial fibrillation is only the latest in a long line of dysrhythmias treated successfully by ablation. Ablative therapy has been used to treat supraventicular tachycardias such as av nodal reentrant tachycardia, atrial flutter, wolff-parkinson-white and others. It is also used to treat types of ventricular tachycardias. Read more...
