Ventricular fibrillation. Basically the patient is dead. Atrial fibrillation causes an irregular heartbeat because the ventricles are receiving disorganized impulses from the SA node. Ventricular fibrillation is where the SA node and the AV node are not firing and the Purkinje fibers are supplying the electrical impulses to the heart. However, the Purkinje fibers are not able to supply enough electricity to contract the ventricles so the heart is twitching but not beating. A heart that is not beating is not circulating blood which means the patient is dead.

∙ 9y agoDuring atrial fibrillation, the atrium does not contract. but blood still flows passively into the ventricle which then pumps it to the body. During ventricular fibrillation, the ventricle does not contract, the body does not receive any blood, and the patient is in cardiac arrest, which is fatal if not reversed.

Atrial fibrillation is often asymptomatic. Usually it is first noticed as an irregular pulse. It can however lead to poor/insufficient heart function and more serious symptoms.

∙ 11y agoThe human heart has two upper chambers and two lower chambers. The upper chambers are called the left atrium and the right atrium - the plural of atrium is atria. The two lower chambers are the left ventricle and the right ventricle. When the two upper chambers - the atria - contract at an excessively high rate, and in an irregular way, the patient has atrial fibrillation. When the two lower chambers beat irregularly and flutter, the patient has ventricular fibrillation
atrial fibrillation refers to the two upper heart chambers
ventricular fibrillation refers to the two lower heart chambers.
Ventricular fibrillation is more serious than atrial fibrillation. Ventricular fibrillation frequently results in loss of consciousness and death,

∙ 13y agoVentricular fibrillation (irregular heart beat) is more deadlier since ventricule is the ultimate pump that pumps blood to the rest of your body.
If a person has atrial fibrillation, the atrium beats 400-600bpm. However, only 100-150 beats will pass through the AV node to the ventricles. At a rate of 100-150 beats, the person's body still receive enough blood to keep the person going.
However, if the ventricle beats 400-600 bpm, there won't be enough blood to be bumped out of the heart to the rest of the body (including the coronary blood vessel). At the end, the person with ventricular fibrillation will die to myocardial infarction or heart attack (due to lack of blood to the coronary blood vessels).

∙ 11y agoV-fib is more dangerous than A-fib, because the in A-fib the ventricles are still pumping blood to the lungs and the body, just at a lower rate than in a sinus rhythm In V-fib the ventricles are just quivering and not moving any blood, which can be a form of cardiac arrest.

What is more serious atrial or ventricular fibrilation?
Ventricular fibrillation is an immediate life threat, so it is more serious.
What heart conditions is propafenone used for?
heart arrhythmias usually of the more dangerous kind. Like ventricular tachycardia and ventricular fibrillation.
What is heart Fibrillation?
Atrial fibrillation is where the electrical impulses within the atria become very rapid and irregular. Atrial rates are usally between 300- 400 BPM or more. How it can happen: 1) Electric shock 2) ion imbalance within heart cells 3) Re- entry pathway. For more information please contactHeartquestionsanswerd@hotmail.co.uk We will answer your question for FREE however use this information as a guide ONLY. I am NOT a doctor but I have been studying the heart for many years and the information here is up=to date.Fibrillation is a medical term and refers to the quivering of a muscle, usually in the heart, as opposed to it contracting properly. Due to uncoordination of the muscle fibrils. Common terms heard are atrial and ventricular fibrillation, the first meaning that the atria of the heart (chamber that fills with blood) is not working well. When ventricular fibrillation occurs, only a small amount of blood is pumped out of the heart. This is the more serious of the two conditions.
What is the difference between ventricular fibrillation and arrhythmia?
Ventricular fibrillation (V fib, VF) is a fatal dysrhythmia that occurs as a result of multiple weak ectopic foci in the ventricles. In other words, there is NO coordinated atrial or ventricular contraction and NO palpable pulse. Ventricular tachycardia (VT or V tach) have three or more PVCs with a rate of >100
Difference between atrial fibrillation and atrial flutter?
They're he same thing. Atrial flutter is more of a slang term, and is sometimes found in patients with atrial tachycardia. Basically, atrial fibrillation is a disorder, and atrial flutter is a symptom
How dangerous is atrial fibrillation?
Atrial fibrillation (A-fib) is a very dangerous condition. In A-fib, the heart is trying to pump too fast, but is uncoordinated. This means that blood is not circulated around the body well. It also causes blood to swirl around inside the heart and can lead to forming blood clots. If one of these blood clots goes to the lungs it can cause a pulmonary embolis, or if it goes to the brain it can cause a stroke, both of which could be deadly.
What conditions require immediate cardioversion?
Ventricular tachycardia lasting more than 30 seconds and ventricular fibrillation require immediate cardioversion.
What does arrhythmia mean?
A condition in which the heart beats with an irregular or abnormal rhythm. Could be PVCs (Premature Ventricular Contractions), slow heart rate (<60 bpm = bradycardia), fast heart rate (>100 bpm = tachycardia), atrial fibrillation, and more
What is Atrial Fibrillation and How Can It Be Treated?
What is atrial fibrillation?Atrial fibrillation is a condition that occurs when the atria, which are the heart's top two chambers, begin to beat erratically. Thyroid problems, heart disease, high blood pressure and drinking alcohol all increase the risk of developing atrial fibrillation. Atrial fibrillation does not always indicate something serious, but it can sometimes lead to strokes and heart failure if it is left untreated.What are some of the symptoms of atrial fibrillation?A racing heartbeat is one of the first symptoms that people with atrial fibrillation will notice. Other symptoms include: chest pain, lightheadness, shortness of breath and decreased blood pressure. Atrial fibrillation can be classified as being acute or chronic. People who have acute atrial fibrillation experience the symptoms every now and then. The symptoms may last for a few hours, but they usually go away on their own. Those who have chronic atrial fibrillation always have an irregular heartbeat.What are some of the treatments available for atrial fibrillation?A doctor will usually prescribe an anti-arrhythmic medication such as Beta Pace and Tambocor. These medications work by helping the heart maintain a normal rhythm. The doctor may also elect to perform a procedure called electrical cardioconversion. Electrical cardioconversion involves stopping the heart with an electric shock. When the heart starts beating again, its rhythm will be normal. A patient is sedated before an electrical cardioconversion is performed.What can be done to prevent atrial fibrillation?There are a few things that people can do to reduce their risk of developing atrial fibrillation. Caffeine and alcohol beverages have a tendency to trigger this condition. That is why the consumption of those type of beverages should be limited. It is also important to limit one's intake of salt and eat more heart healthy foods such as fish, fruits and vegetables. Exercise can also help prevent atrial fibrillation as well as improve the overall health of the heart.
Who are more likely to suffer from atrial fibrillation?
often occurs in people with various types of heart disease. Atrial fibrillation may also result from an inflammation of the heart's covering (pericarditis ), chest trauma or surgery, pulmonary disease, and certain medications
what is treatment for atrial fibrillation and where can I learn more about it?
It is easy, leave the above things, as it's a precipitating cause of your atrial fibrillation. Next you can use a calcium channel blocker, or in extreme cases a ICD is implanted. Talk it out with your doctor, may be he will run a couple of tests.
Hi again, Gene. Atri?
Hi again, Gene. Atrial fibrillation is generally associated with increased morbidity and mortality, and much of this is due to its relationship with ischemic stroke and cardiac disease like heart failure. Among men, estimates range from 1.3-3.5 times more likely for strokes, cardiovascular events (e.g. heart attack), heart failure and death. In your case, however, your risks are probably lower and may even approximate those of people without atrial fibrillation; this is because you have lone atrial fibrillation (at least by some criteria-it is more commonly diagnosed among younger people). Lone atrial fibrillation is diagnosed when no underlying cause or related illness, like heart disease or diabetes, can be found. Because your atrial fibrillation is unassociated with any other symptoms or findings of heart disease, and because you are a non-smoker without obesity or hypertension, your prognosis is better than that of atrial fibrillation in general. The Pradaxa you take is to further reduce your risk of having a stroke.
