What kind of ventricular fibrillation is not dangerous?

What kind of ventricular fibrillation is not dangerous?

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

How long does ventricular fibrillation last?

How long does ventricular fibrillation last?

Ventricular or Atria: Fibrillation is a random chaiotic electrical pattern. Atrial fibrillation is common a 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 lose consciousness in seconds. True vf is life threatening in seconds. ...Read more

What are the symptoms of ventricular fibrillation?

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 are the tests for ventricular fibrillation?

What are the tests for ventricular fibrillation?

Immediate ECG: Ventricular fibrillation is a potentially fatal heart arrhythmia which is 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

Does atrial fibrillation with rapid ventricular response cause ventricular fibrillation?

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

How do class 1b antiarrhythmic drugs help in treating ventricular fibrillation?

How do class 1b antiarrhythmic drugs help in treating ventricular fibrillation?

Sodium Channels: Sodium channels are responsible for the action potential, the depolarization of the heart. These drugs decrease the excitability of the heart because they interfere with the sodium channels. So it will help against ventricular fibrillation. ...Read more

How do antiarrythmic drugs help in the treatment of ventricular fibrillation?

How do antiarrythmic drugs help in the treatment of ventricular fibrillation?

Channel Poisons.: All antiarrhythmic medications are targeted at the channels that allow sodium, potassium, and calcium into and out of cardiac muscles, myocytes.
They target certain channels at a cellular level to slow or break the abnormal rhythm. They often do nothing to fix or correct the problem. ...Read more

How long does ventricular fibrillation usually last without treatment?

Until out of energy: Ventricular fibrillation is a lethal heart arrhythmia which results in no notable blood flow to all the organs. If it does not resolve quickly, either spontaneously, or with defibrillation (shocking), organ damage starts after just a few minutes. If not converted, the rhythm will continue for several minutes until the heart is out of cellular energy,. ...Read more

Is there a cure for ventricular fibrillation?

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

Can beta blockers such as propranolol or toprol (metoprolol) help prevent ventricular fibrillation in susceptible individuals?

Beta Blockers: Yes. Beta blockers are antiarrythmic medications as well as an anti-hypertensive medication. It counteracts the effects of catacholamines like Epinephrine which can cause tachycardia, hypertension and in susceptible individuals ventricular fibrillation. ...Read more

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

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

Ventricular fibrillation fatal?

Ventricular fibrillation fatal?

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

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

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
