Atrial Fibrillation Vs Ventricular 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
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
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
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
It can be: If afib is difficult to treat ie unable to convert patient to normal rythm or unable to slow rate down with medicines, or perhapse the patient can't tolerate the medications to treat the problem, a person can be disabled. Pts with pre existing heart problems may not tolerate afib as well. Ablation therapy is not always effective and some patients may need a pacemaker. Just depends on pt ...Read more
Only if…: Only if the atrial rate is conducted in a very rapid fashion to the lower chamber. Your heart has built-in protection to keep this from happening. However, patients with a condition known as Wolff-Parkinson-White sometimes lack this protection and under the right circumstances can die as a result of atrial fibrillation. ...Read more
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
It depends on: A number of factors. Most people will feel an irregular and skipping or racing sensation in their chest. If the heart rate is too fast or the heart is very weak, you may feel short of breath, weak or even chest pressure. Many people have atrial fibrillation with no obvious symptoms. ...Read more
It depends: Atrial fibrillation is an irregular rhythm in which the atria beat at nearly 400 beats/min. It is common in older patients as a reflection of aging of the conduction system. In younger patients it can be caused by alcohol and drug abuse. It can also occur when the heart dilates as in congestive heart failure. The abnormal contractions put patients at risk for blood clots which may cause strokes. ...Read more
Heart rate / stroke: Two issues with afib. The first is stroke. Afib is a risk for stroke, and thus all patients with afib need some sort of blood thinner. Whether that is an Aspirin or full anticoagulants such as Coumadin (warfarin) depends on your risks and your doctor will let you know that. The second is heart rate. If the afib is too fast or too slow, the rate will need to be treated also. ...Read more
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. ...Read more
Electrocardiogram: If the atrial fibrillation is ongoing then an electrocardiogram will show it. If it only occurs from time to time, then there are different types of monitors that a patient can use at home to record the heart rhythm; this is another type of electrocardiogram sometimes referred to as an event recorder. ...Read more
Irregular: Atrial fibrillation occurs when the atria, which deliver blood to the ventricles, receive an abnormal electrical signal and then beat erratically instead of in a coordinated, strong beat. The danger of atrial fibrillation is that the blood in the atria tends to stay there instead of getting pumped fully into the ventricles. This slow moving blood in the atria can then form blood clots. ...Read more
Atrial fibrillation: You need to see a doc and verify if you have/had afib. Then some basic workup to see if the why can be elucidated. You may or may not need treatment but should be sure the decision is made from the proper information. ...Read more
