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

Atrial Fibrillation (Definition)

A heart condition, in which the electrical activity of the heart is abnormal. This abnormal electrical signal causes the heart muscle to contract when it is not supposed to and thus blood is ...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

What is more dangerous, atrial fibrillation or ventricular fibrillation?

For: 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

What is the difference between atrial fibrillation and ventricular fibrillation?

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

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 makes atrial fibrillation not immediately life threatening while ventricular fibrillation is?

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

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

How does atrial fibrillation with ventricular standstill differ from fine v-fib?

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?

Afib/vfib: 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

Would echo,ekg,stress test,xray,bloodwork rule out any arrhythmia problem such as premature ventricular contraction and paroxysmal atrial fibrillation?

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

Does atrial fibrillation get worse as one gets older?

Worsening AF: Af is usually a progressive issue. The progression varies with each person - months, years, decades. It usually increases in frequency or duration over time but there is no defined interval in any specific person. Af causes changes in the electrical properties of the atrium to increase the chances for more af. Therapy with drugs or ablation may decrease the chances of progression. Talk to you md. ...Read more

Are there any steps I can take to prevent mild atrial fibrillation from getting worse?

Are there any steps I can take to prevent mild atrial fibrillation from getting worse?

Stay or get healthy: There are many things that may worsen atrial fibrillation. These include excessive alcohol use, caffeine and being overweight. If any of these apply to you, try to improve them. You should also work with your doctor to ensure you don't have an underlying heart valve problem, coronary artery disease or a thyroid disorder that is causing atrial fibrillation. ...Read more

What can make my atrial fibrillation worse? What are the risks that my atrial fibrillation will become worse? (more symptomatic)

Symptoms can be wors: The symptoms of atrial fibrillation can get better or worse. But this does not mean the a fib is itself getting worse. Anything that makes you heart go faster, will give you a more significant sensation. Things like fever, stimulants (caffeine), stress, excitement will make your heart beat faster. But, again, this does not mean your condition is at all worse. Medications can also affect symptoms. ...Read more
