Question 1

how long does ventricular fibrillation last?

Accepted Answer

Ventricular or Atria: Fibrillation is a random chaiotic electrical pattern.  Atrial fibrillation is common an some older adults live in continuous a-fib and feel ok while on medications that slow the ventricular response to the atrial rate.
Ventricular fibrillation is not tolerated, meaning someone having true ventricular fibrillation will loose consciousness in seconds.  True vf is life threatening in seconds.

Question 2

what are the tests for ventricular fibrillation?

Accepted Answer

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.

Question 3

what are the symptoms of ventricular fibrillation?

Accepted Answer

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.

Question 4

what kind of ventricular fibrillation is not dangerous?

Accepted Answer

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.

Question 5

what causes a person to have ventricular fibrillation vfib?

Accepted Answer

Low oxygen...: Anything that results in low oxygen to the heart muscle can result in ventricular fibrillation including a myocardial infarct, or mi.

Question 6

what is the definition or description of: ventricular fibrillation?

Accepted Answer

Sudden cardiac death: fibrillation of ventricle results in cardiac arrest and sudden cardiac death due to very fast (more tan 300 beats/min) in lower heart chambers

Question 7

how can someone know if they are experiencing ventricular fibrillation?

Accepted Answer

Fatal: Ventricular fibrillation is usually fatal if not treated immediately with defibrillation.

Question 8

what is the disease where ventricular fibrillation happens all the time or a lot of the time?

Accepted Answer

V-fib???: V-fib that lasts more than a few seconds is typically lethal and results in sudden death.  Atrial fibrillation (a-fib) is a different thing entirely, which is a common heart rhythm abnormality.  Some people live in constant afib, some people their afib is come-and-go.  If it is afib you are referring to, it is commonly managed with a combination of medications and procedures.

Question 9

is there a p wave in ventricular fibrillation?

Accepted Answer

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.

Question 10

how come there is no p wave in ventricular fibrillation?

Accepted Answer

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.
