Ablation (Definition)

Cardiac ablation involves destruction of tissue aimed at elimination of sources of origin or propagation of arrhythmias. It may also be used to destroy part of the heart in hypertrophic cardiomyopathy. Typically it is done with a catheter inserted through a ...Read more

How much rate atrial fibrillation with slow ventricular ?

How much rate atrial fibrillation with slow ventricular ?

Usually < 60-70: Most people, left untreated, have rates between 70 and 150. It's a bit unusual to fall below that without drugs or other treatment. ...Read more

Does atrial fibrillation with rapid ventricular response cause ventricular fibrillation?

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

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

How effective are ablations for atrial fibrillations?

Not very effective. : Ablation for regular tachcardias such as supraventricular tachycardia or atrial fibrillation is very successful (>90%). Ablation for atrial fibrillation which is chaotic rhythm is either not successful or if initial success, the positive outcome is not sustained. In other words there is a high rate of recurrence. ...Read more

Would a pacemaker repair atrial fibrillation?

Would a pacemaker repair atrial fibrillation?

Not directly.: 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

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

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

What is the success rate of ablation of atrial tachycardia?

What is the success rate of ablation of atrial tachycardia?

Great question: It's variable depending on location (left vs right sided). Talk to the electrophysiologist who would perform to get best information specific. ...Read more

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

How are atrial fibrillation and atrial flutter different?

How are atrial fibrillation and atrial flutter different?

Irregular/ regular: Heart rythm problem is more unpredictable in a fib. In flutter the are more predictable and regular rate. The treatment approach differs and risk of intracardiac blood clot also in that context. ...Read more

Can pacemaker fix all cases of atrial fibrillations?

Can pacemaker fix all cases of atrial fibrillations?

No: Atrial fibrillation is an irregular heartbeat of the upper chambers of the heart. Its greatest danger is the formation of bloodclots within the heart which can trravel up to the brain and cause a stroke. Patients with af are generally treated with anticoagulants or blood thinners like aspirin, warfarin (coumadin) or dabigatran (pradaxa) to prevent strokes and medication to control the heart rate. ...Read more

Can radiofrequency cardiac ablation help cure arrhythmia?

Can radiofrequency cardiac ablation help cure arrhythmia?

Yes: The more general term for the procedure is catheter ablation. In essence the abnormal tissue in the heart that is supporting or causing the arrhythmia can be destroyed by either burning it (radiofrequency ablation) or by freezing it (cryoablation). For many arrhythmias, this treatment is highly effective with cure rates approaching 100%. ...Read more

Is an irregular heart beat usually atrial fibrillation?

Not always: It certainly can be. Although there are multiple instances when one can have an "irregular heartbeat'. You should see your doctor so an ekg can be done or possibly a monitoring device ordered to evaluate further. ...Read more
