What is worse: ventricular fibrillation or atrial fibrillation?

What is worse: ventricular fibrillation or atrial fibrillation?

Ventricular fib: Vf is worse; it usually causes cardiac arrest which is often fatal. Atrial fibrillation, while not as severe, also has significant health risks. It increases the risk of stroke, which can be disabling or fatal. Additionally, if the af causes a fast pulse for a prolonged period of time, this may lead to weakening of the heart and cause heart failure. ...Read more

Why is ventricular fibrillation worse than atrial fibrillation?

Why is ventricular fibrillation worse than atrial fibrillation?

Fibrillation: atrial fibrillation has normal left ventricular contractions put poor atrial function. Ventricular fibrillation has no real ventricular contractions so blood pumping essentially stops. Atrial fibrillation is a rhythm you can live with. Ventricular fibrillation is a rhythm you die with unless it is corrected quickly. ...Read more

Can atrial fibrillation with rapid ventricular beat cause ventricular fibrillation?

Can atrial fibrillation with rapid ventricular beat cause ventricular fibrillation?

Not usually: Not typically; however, if you also have an accessory pathway (wolff-parkinson-white syndrome), this is a unique situation where af is known to cause very rapid ventricular activation during af, which can lead to vf. Rapid ventricular response may cause cardiac weakening over time, which in turn may increase the risk of vf. ...Read more

Does atrial fibrillation with rapid ventricular response cause ventricular fibrillation?

Only in a Very Few: Generally, the answer to this is a very solid "no." this is a rare complication of people with another condition (on top of their afib) called wolff-parkinson-white syndrome (or wpw). In certain patients having both conditions, the top chamber is too-well connected to the bottom and can trigger ventricular fibrillation. ...Read more

What is Paroxysmal atrial fibrillation?

What is Paroxysmal atrial fibrillation?

Irregular pulse: Paroxysmal atrial fibrillation is an abnormal heart rhythm that is intermittent (or paroxysmal), arising from the upper chambers of the heart (or atria), and is very chaotic, or irregular (fibrillating). It can cause problems because it usually drives the heart rate up too fast (giving symptoms and eventually weakening the heart) and can increase the risk of stroke. Causes of PAF are multiple. ...Read more

How is atrial fibrillation treated?

How is atrial fibrillation treated?

Several options: With medications to slow down the heart rate or control the heart rhythm, in the right setting blood thinners to minimize the risk of stroke, electrical shock to restore a normal rhythm and also catheter based approaches in order to remove the trigger for afib. ...Read more

Without treatment, is atrial fibrillation deadly?

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

Is atrial fibrillation inherited?

Sometimes: There is a gene that makes the tendency to get it more likely, but most a fib is due to environmental and aquired factors such as age, valvular heart disease and alcohol. ...Read more

Which treatments control atrial fibrillation?

Which treatments control atrial fibrillation?

It Varies: The most important treatment is stroke prevention, which is usually done by medications (aspirin or warfarin). Sometimes rate control medications are used, like metoprolol. If the af is severe enough, stronger anti-arrhythmic medications are used, like propafenone. If these do not work, catheter ablation may be recommended. Pacemaker and av-node ablation may be used as a last resort. ...Read more

How is atrial fibrillation diagnosed?

How is atrial fibrillation diagnosed?

EKG /Physical exam: Different ways. Listening to the heart there is obvious irregular rhythm with irregular rate. The electrocardiogram is diagnostic. Some times atrial fibrillation may appeared transiently or paroxystically. A holter monitor or cardiac monitor could show the characteristic features of the EKG changes. ...Read more

How effective is diltiazem (Cardizem) for managing atrial fibrillation?

Effective: Controlling the heart rate is an important part of treating atrial fibrillation. This can be done with a calcium channel blocker, such as diltiazem or verapamil, or a beta-blocker. Also important is anticoagulation, and consideration of restoring sinus rhythm. ...Read more

What is atrial fibrillation?

Arrhythmias: Atrial fibrillation (afib) is the most common sustained rhythm abnormality. It's characterized by an irregular heart rate. The upper chambers of the heart (atrium) do not beat but quiver. Many people don't notice it. But many do. It can lead to strokes in some patients so blood thinners are important. It can be treated with medications, ablation thru iv's in the groin or surgery. See a cardiologis. ...Read more

Can you describe non-valvular atrial fibrillation?

How effective is digoxin (Lanoxin) for managing atrial fibrillation?

Digoxin: we have used it for hundreds of years, recently it has been falling into disfavor. It needs to be used with great care and this may be why recent usage problems are seen. It is an ancient poison so it can't be taken lightly. ...Read more

Which is better and more safe in general for treating hypertension and atrial fibrillation metoprolol succinate or bisoprololesp. If s.creatinine1.56 ?

Which is better and more safe in general for treating hypertension and atrial fibrillation metoprolol succinate or bisoprololesp. If s.creatinine1.56
?

Neither. In clinical: trials, carvedilol has significantly better outcomes than either metoprolol (e.g. 3%/yr lower mortality rates continuing for many years) or bisoprolol. Creatinine is quite another issue, produced by all muscle cells, yet used to crudely estimate renal filtering function, not the 4 known responses to carvedilol. Yet the clinical trial data for all the Beta blockers is as augmenters to ACEI agents. ...Read more
