How Long Should Ventricular Fibrillation Last
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. ...Read more
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

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. ...Read more

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. ...Read more
ECG: There may actually be a P wave in some vfib. You won't see it because of the vfib waves. ...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
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
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
None: Vf is a life threatening emergency which requires immediate cardioversion. ...Read more
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
Let me help myou:
Digoxin is a heart stimulant with a very narrow range of safe doses.
Ventricular tachycardia is very common adverse side effect of digoxin, and would likely make this condition worse or increase the frequency of the episodes.
Stimulating a heart that is already beating too fast (tachycardia) could be fatal. Good luck. ...Read more

When should u worry about escape rhytms and ventricular fibrillation due to overactive parasympathic nervous system? And heartblock?
Complicated question: Hard to answer without more info and more space. Escape rhythms are like a "back-up" rhythm, and are generally protective rather than concerning. Lower grade heart block also is usually not symptomatic, and it doesn't sound like you're dealing with anything that might progress to 3rd degree AV block. As for VFib, an overactive parasympathetic system shouldn't really put you at risk for that. ...Read more
Can small VSD cause ventricular fibrillation in young adult? Ped. Cardiologist said no need for SX, because VSD is too small. Very worried!
Complicated question: Use HealthTap Prime to get better advice, as we're limited in characters in this forum. How young is the young adult? Half or more of VSDs can close (or shrink) with age. So there may be time to grow out of it. Large VSDs are associated with arrhythmias like VFib (upto 25%). If you've had VFib, that's one thing, but if you've never had it, then surgery isn't preventive & carries its own risk. FYDA ...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
Very likely: Very likely especially if the first one was not treated. Somewhat less likely if the first one was treated and predisposing factors were identified and eliminated, but still possible e.g. Unidentified additional predisposing factors or just heart tissue being more sensitive. ...Read more
Yes: Usually propel who have CHF have a poor lv function; less than 35%. With this diagnosis your heart has the propensity to go into very dangerous rhythms: ventricular tachycardia and ventricular fibrillation. With these arrhythmias you are rendered dead, without a blood pressure, etc. Hence, why you are recommended to get an implantable cardioverter defibrillator when you have a cardiomyopathy. ...Read more
Help plz! Can severe hypoxia cause bradydysrhythmias more often than ventricular fibrillation and why?
What is the difference between ventricular fibrillation and ventricular re-entrant tachycardia? And which is more severe?
Circulation: Ventricular fibrillation is totally disorganized and does not effectively pump blood. Untreated, this will be fatal. Ventricular tachycardia is organized, and depending on the rate, and the part of the heart it originates from, may be able to generate an effective blood pressure, at least for awhile. Serious, but not always fatal. ...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
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
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
