What are the tests for ventricular fibrillation?

Immediate ECG. Ventricular fibrillation is a potentially fatal heart arrhythmia which if not reversed back to a normal rhythm, can cause permanent stoppage of the heart. It always causes patients to lose conciousness and cause cardiovascular collapse. These patients need to have immediate confirmation of their rhythm disturbance and be defibrillated immediately to prevent death. Read more...

What are the symptoms of ventricular fibrillation?

Cardiac arrest. Ventricular fibrillation is a fatal arrhythmia that results in death unless reversed with defibrillation. The main symptoms are cardiovascular collapse with absence of blood pressure, pulselessness, and total unresponsiveness to any stimuli. Read more...

What kind of ventricular fibrillation is not dangerous?

None. Ventricular fibrillation is a condition in which there is uncoordinated contraction of the cardiac muscle of the ventricles in the heart, making them quiver rather than contract properly. Ventricular fibrillation is a medical emergency and a commonly identified arrythmia in cardiac arrest patients. Ventricular fibrillation is a medical emergency that requires prompt emergency intervention. Read more...
Ventricular fibrilla. Ventricular fibrillation means the heart is not mechanically contracting and thus isn't pumping blood. There is no kind of ventricular fibrillation that isn't life threatening unless it is the kind which is pseudovfib meaning it isn't really fibrillating, it just looks that way on the ecg.

Ventricular fibrillation fatal?

Usually. Almost always. It may terminate on it's own in some circumstances, but not very often. If you had a internal or external defibrillator, then you could terminate the vf before it was fatal. Read more...
Possibly.. In ventricular fibrillation, vfib, the heart is quivering and there is no blood flow so the person is clinically dead. If the heart cannot be restored to a rhythmn where there is blood flow, the patient will then be pronounced dead. Treatment for this rhythmn includes electrically shocking the heart as quickly as possible. Performing CPR in the meantime can be life-saving. Read more...
Vf. yes, if it does not stop in time or of if its not stopped by defibrillation in time. Read more...

Is there a cure for ventricular fibrillation?

I do not think so. Absolutely not. This is the most dangerous arrhythmia one can have because it can quickly deteriorate to asystole. V-fib is a shockable rhythm and a victim will most likely be pulseless. It must be treated with defibrillation, cpr, epinephrine/vasopressin, amiodarone, Lidocaine and/or magnesium. It's not something you can treat at home with a cup of herbal tea. And anyway, you'd be unconscious. Read more...

Is there a P wave in ventricular fibrillation?

Not visibly. . There is usually atrial activity, either the occasional retrograde atrial activation, or just the normal sinus rate progressing along unaffected by the vf. However, with the continuous ventricular activity in vf, it would typically be impossible to make out a p wave on the surface ekg. When we have catheters in the heart (during an ep study) we see the atrial activity in vf. Read more...
No... There is no organized rhythmn in ventricular fibrillation so no p wave is present. There is also no qrs complex present. There is no blood flow as the heart is quivering so the patient is clinically dead. The heart needs to be shocked as quickly as possible to hopefully restore a normal rhythmn. Read more...
Vf. they are masked by extremely rapid electrical storm in the heart, so can't see them in ECG. Read more...

How come there is no P wave in ventricular fibrillation?

P waves are atrial. "p" wave are a finding on the ECG (electrocardiogram) which represents atrial contraction. During ventricular fibrillation there is no organized atrial activity and therefore there will be no p wave generated. Read more...

What causes a person to sweat when they have ventricular fibrillation?

Sympathetic system. Ventricular fibrillation, which is usually a very short-lived event, usually occurs in a high sympathetic output state, at times the high sympathetic output actually is the cause for ventricular fibrillation but in any case the end result is the same. As the sweat glands receive their innervation from this system of nerves, their output increases and the person sweats profusely. Read more...
Vfib. Ventricular fibrillation causes the heart to not contract, blood flow to the body ceases and the patient will die if normal or contractile rhythm isn't returned. Sweating is a response to low blood pressure. When blood pressure drops with atrial fibrillation patients may have sweating. Ventricular fibrillation long enough to cause perceived sweating unlikely unless reversed to better rhythm. Read more...
