Can ventricular fibrillation stop on its own?
Ventricular fibrillation seldom terminates spontaneously, since several re-entrant wavefronts, independent from each other, coexist, and the simultaneous extinction of all the circuits is unlikely.
Can you be conscious in V fib?
Defibrillators don't treat cardiac arrest. Instead, they treat ventricular fibrillation, one form of cardiac arrest. That's why they're called de-fibrillators. There's absolutely no way a patient with ventricular fibrillation could be awake; no blood flowing through the brain makes the patient unconscious.
How does amiodarone stop ventricular fibrillation?
Amiodarone is a potent antiarrhythmic agent that is used to treat ventricular arrhythmias and atrial fibrillation. The drug prevents the recurrence of life-threatening ventricular arrhythmias and produces a modest reduction of sudden deaths in high-risk patients.

Treatment of torsade de pointes includes: isoproterenol infusion, cardiac pacing, and intravenous atropine. Intravenous magnesium sulfate, a relatively new mode of therapy for torsade de pointes, was proven to be extremely effective and is now regarded as the treatment of choice for this arrhythmia.
What is VF in cardiac arrest?
Ventricular fibrillation (VF or V-fib) is the most common initial heart rhythm in patients with out-of-hospital cardiac arrest (OHCA), and the most salvageable one . 5 In VF, the etiology of arrest is often attributed to either acute ischemia or non-ischemic arrhythmia. 8
What are the causes of VF?
The easiest way to remember the most common causes of VF are to review the reversible “Hs and Ts” in cardiac arrest. The Hs include hypoxia, hypovolemia, hypothermia, hyper/hypokalemia, and hydrogen ions (acidosis). The Ts are tension pneumothorax, cardiac tamponade, toxins, and thrombosis (pulmonary or coronary).
What is a cardioverter defibrillator?
An implantable cardioverter defibrillator is a device for people who are prone to life-threatening rapid heart rhythms. It is slightly larger than a pacemaker and usually is implanted beneath the skin below the collarbone. It is connected to a defibrillation/pace wire (s) positioned inside the heart via a vein. It has the capability of delivering an electric shock to the heart when it determines the heart rate is too fast. It also is capable of pacing or stimulating the heart when it is going too slow.
How to cure atrial flutter?
Currently, atrial flutter is successfully "cured" by radiofrequency catheter ablation; but treatment to restore atrial fibrillation to sinus rhythm has been the traditional use of medications and external cardioversion.
What is radiofrequency ablation?
A technique pioneered at UCSF, radiofrequency catheter ablation destroys or disrupts parts of the electrical pathways causing the arrhythmias, providing relief for patients who may not have responded well to medications, or who would rather not or can't take medications.
How do pacemakers work?
They are small devices that are implanted beneath the skin below the collarbone and connected to a pace wire (s) positioned inside the heart via a vein; this delivers a small electrical impulse to stimulate the heart to beat when it is going too slow.
When was internal cardioversion developed?
Internal cardioversion for conversion of atrial fibrillation and atrial flutter to a normal sinus rhythm was developed here at UCSF Medical Center in 1991. Internal cardioversion is low energy electrical shock (1 to 10 joules) delivered internally in the heart through two catheters inserted in a vein in the groin and a small electrode pad applied to the chest. This procedure is performed in the electrophysiology lab by our electrophysiologist.

What is worse AFib or VFib?
Which Is Worse, AFib or VFib? Although both atrial fibrillation and ventricular fibrillation may cause serious medical problems with a patient. Ventricular fibrillation, especially if it is sustained, is considered far more serious as the patient can quickly develop “sudden death” or “cardiac arrest,” and die.
Can stress cause ventricular fibrillation?
Stress can cause a heart attack, sudden cardiac death, heart failure, or arrhythmias (abnormal heart rhythms) in persons who may not even know they have heart disease. Lower threshold for abnormal heart rhythms including ventricular tachycardia, ventricular fibrillation, and atrial fibrillation.
Which type of fibrillation is the most serious?
Ventricular fibrillation is more serious than atrial fibrillation. Ventricular fibrillation frequently results in loss of consciousness and death, because ventricular arrhythmias are more likely to interrupt the pumping of blood, or undermine the heart’s ability to supply the body with oxygen-rich blood.
Can V fib be cured?
Key points about ventricular fibrillation CPR and defibrillation can restore your heart to its normal rhythm and may be life saving. Medicines and certain procedures after an episode of ventricular fibrillation can prevent or reduce the chances of another episode. An ICD can promptly treat V-fib.
Is ventricular fibrillation hereditary?
There are a number of inherited disorders that can cause arrhythmias and sudden cardiac death. Some of these are very rare. The more common ones include: Brugada Syndrome: a genetic disorder of the heart rhythm that can cause ventricular fibrillation and sudden cardiac arrest.
What is the difference between atrial fibrillation and PVC?
In atrial fibrillation, the starting and conduction cells are abnormal. This causes an abnormal rhythm or beating pattern of the heart. Any abnormal pattern is called an arrhythmia. Palpitations are commonly caused by premature contractions of the ventricles (the large heart chambers) and are called PVCs.
