Is Atrial Fibrillation Or Ventricular Fibrillation More Serious
Any chances to "recover" from vfib one need to be in an intensive care an hooked to an ekg. And a slim chance to live. If someone collapses on the street, help has to come in minutes to jump heart back to normal rhythm. People who go in vfib have an underlying and severe heart disease.
Conclusion vfib kills a afib can be controlled, even normal rhythm may be restored. Big difference! ...Read more
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
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
It depends: Ventricular fibrillation is from the bottom chamber; vf is worse; it usually causes cardiac arrest which is often fatal. Atrial fibrillation - from the top chamber- while not as severe, also has significant health risks. It increases the risk of stroke, which can be disabling or fatal. ...Read more
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
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 makes atrial fibrillation not immediately life threatening while ventricular fibrillation is?
A circuit breaker: The rhythms in the top chamber during atrial fibrillation can reach and exceed 600 bpm. If this were conducted directly to the lower chamber, it would be as fatal as ventricular fibrillation. However, nature built in a circuit breaker called the av node between the two such that only some of the top chamber heartbeats in fibrillation make it to the bottom chamber. ...Read more
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
AF vs vf: Good question, they could look alike on ECG. Both would also result in cardiac arrest. As no perfusion would result, one would expect AF waves to be less visible than VF very quickly. If arrest had been present for say more than 30sec., VF would be more likely as the AF waves should likely not be visible. ...Read more
Can you tell me if atrial fibrillation with ventricular standstill is recognized from fine v-fib?
Ventricular standstill and fine v-fib are functionally the same the ventricle is not contracting - vfib is a slight quivering which may or may not be identifiable on ECG;
if the ventricle is not contracting then it is not possible to non-invasively identify atrial fibrillation from simply sinus/atrial arrest. ...Read more
Does left ventricular atrial fibrillation in te past wid medication hav a say on sex life. Does impotency n premature ejaculation result from it.
Would echo, ekg, stress test, xray, bloodwork rule out any arrhythmia problem such as premature ventricular contraction and paroxysmal atrial fibrillation?
No: Occasional PVCs are normal. Paroxysmal atrial fibrillation by definition is only present some of the time and the tests you list could easily miss this if done while the heart is in normal rhythm. Diagnosis of intermittent arrhythmias can be difficult and frequently requires consultation with a cardiologist subspecialized in electrophysiology, Holter monitor test is frequently used. ...Read more
Do beta blockers such as toprol (metoprolol) help to prevent atrial and ventricular fibrillation?
Yes to an extent: More beneficial to prevent af than vf! ...Read more
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. ...Read more
Both can be: Atrial fibrillation and flutter are both common arrythmias. Flutter tends to degenerate into fibrillation; the difference is that flutter tends to be regular and fibrillation irregular. Generally speaking, irregular is worse than regular because there is a higher risk of clots forming in the heart which can then cause strokes and other potential problems. Most flutter will become fibrillation. ...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. Talk to your dr. About it if you have it. ...Read more
Not usually: Atrial fibrillation may be a consequence of structural abnormalities of the heart, which can indeed be serious. However, if the rhythm disturbance is the only abnormality then it can usually be controlled sufficiently that the patient can be free of symptoms. In older patients with af there is significant risk of stroke, but this too can be mitigated by treatment to reduce blood clots. ...Read more
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. ...Read more
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. ...Read more
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. ...Read more
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. ...Read more
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. ...Read more
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. ...Read more
