Which is more serious atrial or ventricular fibrillation?
People with AFib are five times more likely to have a stroke versus people who don't have the condition. They also have a higher risk of heart failure, heart attack, cardiac arrest, and dementia. While not as common as AFib, ventricular fibrillation is more deadly.
In AFib, the heart's rate and rhythm will become irregular. Although serious, AFib is not typically an immediately life-threatening event. In VFib, the heart will no longer pump blood. VFib is a medical emergency that will lead to death if not treated promptly.
During ventricular fibrillation, the lower heart chambers contract in a very rapid and uncoordinated manner. As a result, the heart doesn't pump blood to the rest of the body. Ventricular fibrillation is an emergency that requires immediate medical attention. It's the most frequent cause of sudden cardiac death.
Ventricular fibrillation is more serious than atrial fibrillation. Ventricular fibrillation frequently results in loss of consciousness and death, because ventricular arrhythmias are more likely to interrupt the pumping of blood, or undermine the heart's ability to supply the body with oxygen-rich blood.
Permanent atrial fibrillation
This means your heart is in a state of AFib all the time. According to research , this type of AFib may result in more severe symptoms, lower quality of life, and an increased risk of a major cardiac event.
Atrial fibrillation isn't usually life-threatening or considered serious in people who are otherwise healthy. However, atrial fibrillation can be dangerous if you have diabetes, high blood pressure or other diseases of the heart. Either way, this condition needs to be properly diagnosed and managed by a doctor.
SCD is the most common cause of cardiovascular death in patients with atrial fibrillation and has several distinct predictors, some of which are modifiable. These findings may be considered in planning research and treatment strategies for patients with atrial fibrillation.
The chance of survival from ventricular fibrillation (VF) is up to ten times higher than those with other cardiac arrest rhythms.
In AFib, the abnormal heart rhythm is due to irregular electrical activity in the upper chambers of the heart muscles, the atria, mainly the right atrium. Usually, it results in a fast and irregular heartbeat. VFib occurs when the electrical signal is irregular within the lower chamber heart muscles (ventricles).
Ventricular fibrillation is a type of arrhythmia, or irregular heartbeat, that affects your heart's ventricles. Ventricular fibrillation is life-threatening and requires immediate medical attention.
What is the best treatment for ventricular fibrillation?
External electrical defibrillation remains the most successful treatment for ventricular fibrillation (VF). A shock is delivered to the heart to uniformly and simultaneously depolarize a critical mass of the excitable myocardium.
Amongst the group of patients aged between 55-74 years, the 10 year mortality was 61.5% in men with AF compared to 30% in men without AF. Amongst women in a similar age group, the 10 year mortality was 57.6% in the AF group versus 20.9% in women without AF.
You may need a pacemaker if: You have atrial fibrillation that comes and goes. And you have a fast heart rate when you are in atrial fibrillation and a slow heart rate when you are not in atrial fibrillation. This is called tachy-brady syndrome.
First call 911 or your local emergency number. Then start CPR by pushing hard and fast on the person's chest — about 100 to 120 compressions a minute. Let the chest rise completely between compressions. Continue CPR until an automated external defibrillator (AED) is available or emergency medical help arrives.
It shows an irregular wide-complex tachycardia with different degrees of QRS widening, consistent with preexcited atrial fibrillation with very fast conduction to the ventricles. At the end of the strip, QRS complexes become smaller and erratic as atrial fibrillation turns into ventricular fibrillation.
Heart failure
If your atrial fibrillation is persistent, it may start to weaken your heart. In extreme cases, it can lead to heart failure, as your heart is unable to pump blood around your body efficiently.
This is alarming, because having AFib carries serious risks including stroke, congestive heart failure and death. One of the most common heart rhythm disorders, AFib is a serious, but treatable condition characterized by a racing or fluttering heartbeat.
“But poor sleep is just one of many triggers for Afib,” said Ghannam, noting alcohol, excessive exercise, dehydration, stress and consuming large meals as some of the more common ones. “It just depends on the individual and his or her experience.”
While patients who have elevated stroke risks may be able to manage symptoms of AFib — such as a racing heartbeat — with other medications or medical procedures, they will still need to take blood thinners to protect against stroke.
Yes. Your risk of developing atrial fibrillation, a common heart rhythm disorder, increases as you become older. Atrial fibrillation is much more common in older adults. Atrial fibrillation can occur at any age, but when it develops in younger people, it's usually associated with other heart conditions.
What is the latest treatment for atrial fibrillation?
Treating AFib
However, the expert heart care team at Adventist HealthCare White Oak Medical Center now offers a new treatment for AFib, the WATCHMAN™ heart implant. The implant is placed during a one-time, minimally invasive procedure and lowers the risk of bleeding and stroke in AFib patients.
- Warfarin (also known as Coumadin and Jantoven)
- Apixaban (also known as Eliquis)
- Rivaroxaban (also known as Xarelto)
- Aspirin.
- Enoxaparin (also known as Lovenox)
- Clopidogrel (also known as Plavix)
- Heparin.
- Dabigatran (also known as Pradaxa)
Certain situations can trigger an episode of atrial fibrillation, including: drinking excessive amounts of alcohol, particularly binge drinking. being overweight (read about how to lose weight) drinking lots of caffeine, such as tea, coffee or energy drinks.
New-onset AF has been associated with cardiovascular drugs such as adenosine, dobutamine, and milrinone. In addition, medications such as corticosteroids, ondansetron, and antineoplastic agents such as paclitaxel, mitoxantrone, and anthracyclines have been reported to induce AF.
A dual chamber pacemaker paces the atrium and ventricle. A biventricular pacemaker paces both ventricles. An implantable cardioverter-defibrillator can work as a pacemaker would. In addition, if it detects ventricular tachycardia or ventricular fibrillation, it sends out a shock to reset the heart to a normal rhythm.
Ventricular fibrillation seldom terminates spontaneously, since several re-entrant wavefronts, independent from each other, coexist, and the simultaneous extinction of all the circuits is unlikely.
Ventricular fibrillation and consciousness are not mutually exclusive.
Heart failure, which occurs when the heart can't pump enough blood to the rest of the body, is one of the most common complications associated with atrial fibrillation. Once patients with atrial fibrillation develop heart failure, their risk of death significantly increases.
Is AFib or VFib more serious and dangerous? By far, VFib is more serious. If ventricular fibrillation isn't treated immediately, the patient will have a “sudden death” or “cardiac arrest” and die.
AFib is a serious diagnosis. While this condition isn't fatal in itself, it can lead to potentially life-threatening complications. Two of the most common complications of AFib are stroke and heart failure, both of which can be fatal if not managed quickly and effectively.
Is atrial or ventricular tachycardia worse?
Although both atrial fibrillation and ventricular fibrillation may cause serious medical problems with a patient. Ventricular fibrillation, especially if it is sustained, is considered far more serious as the patient can quickly develop "sudden death" or "cardiac arrest," and die.
Untreated AFib can raise your risk for problems like a heart attack, stroke, and heart failure, which could shorten your life expectancy. But treatments and lifestyle changes can help prevent these problems and manage your risks.
People with atrial fibrillation are at increased risk of having a stroke. In extreme cases, atrial fibrillation can also lead to heart failure.
- Go to a healthier-fat, low-salt diet. Avoid saturated fat, trans fat, and salt to help control your blood pressure and cholesterol levels. ...
- Limit caffeine. ...
- Cut back on alcohol. ...
- Regular amounts of vitamin K.
A beta blocker, such as bisoprolol or atenolol, or a calcium channel blocker, such as verapamil or diltiazem, will be prescribed. The medicine you'll be offered will depend on what symptoms you're having and your general health. A medicine called digoxin may be offered if other drugs are not suitable.
Certain situations can trigger an episode of atrial fibrillation, including: drinking excessive amounts of alcohol, particularly binge drinking. being overweight (read about how to lose weight) drinking lots of caffeine, such as tea, coffee or energy drinks.

The good news is that although AF is a long-term condition, if managed correctly, you can continue to lead a long and active life. There are a number of steps you can take that will help you manage your condition, lower your risk of stroke and relieve any worries you may have.
Yes. Your risk of developing atrial fibrillation, a common heart rhythm disorder, increases as you become older. Atrial fibrillation is much more common in older adults. Atrial fibrillation can occur at any age, but when it develops in younger people, it's usually associated with other heart conditions.
With proper treatment, individuals with atrial fibrillation can live normal and active lives. Atrial fibrillation, commonly referred to as AF or a-Fib, is the most commonly occurring arrhythmia, or heart rhythm problem. AF is characterized by an abnormal or irregular heart rhythm that causes a rapid heart rate.
How do you know if your atrial fibrillation is permanent?
In persistent AFib, your symptoms last longer than seven days, and your heart's rhythm isn't able to regulate itself anymore. The other two main types of AFib are: paroxysmal AFib, in which your symptoms come and go. permanent AFib, in which your symptoms last for more than a year.
