How long does ventricular fibrillation usually last without treatment?

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

Ventricular Fibrillation (Definition)

Ventricular fibrillation is a condition where there is an uncoordinated electrical stimulation to the ventricles of the heart, causing the muscles to contract individually rather than together as a group response. The heart is unable to pump ...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 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

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

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

When should u worry about escape rhytms and ventricular fibrillation due to overactive parasympathic nervous system? And heartblock?

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

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

Is it common for people with CHF to experience ventricular fibrillation?

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

What is the difference between atrial fibrillation and ventricular fibrillation?

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
