Ventricular fibrillation (V-fib or VF) is an abnormal heart rhythm in which the ventricles of the heart quiver. [2] It is due to disorganized electrical activity. [2] Ventricular fibrillation results in cardiac arrest with loss of consciousness and no pulse. [1] This is followed by sudden cardiac death in the absence of treatment. [2]
Primary ventricular fibrillation (PVF) is an unpredictable [1] and potentially fatal arrhythmia occurring during the acute phase of a myocardial infarction leading to immediate collapse and, if left untreated, leads to sudden cardiac death within minutes.
Defibrillation is a treatment for life-threatening cardiac arrhythmias, specifically ventricular fibrillation (V-Fib) and non-perfusing ventricular tachycardia (V-Tach). [1] [2] A defibrillator delivers a dose of electric current (often called a counter-shock) to the heart.
The main cause of cardiac arrest is two types of arrhythmias called ventricular fibrillation or ventricular tachycardia. Other potential causes include: ... Cardiovascular Disease Treatment.
Precordial thump is a medical procedure used in the treatment of ventricular fibrillation or pulseless ventricular tachycardia under certain conditions. The procedure has a very low success rate, but may be used in those with witnessed, monitored onset of one of the "shockable" cardiac rhythms if a defibrillator is not immediately available.
The mechanism responsible for the majority of sudden cardiac deaths is ventricular fibrillation. Ventricular fibrillation is a tachyarrhythmia characterized by turbulent electrical activity in the ventricular myocardium leading to a heart rate too disorganized and rapid to produce any meaningful cardiac output, thus resulting in insufficient ...
It is also used in the emergent treatment of wide complex tachycardias, including ventricular tachycardia, when a pulse is present. Pulseless ventricular tachycardia and ventricular fibrillation are treated with unsynchronized shocks referred to as defibrillation.
The ICD is the first-line treatment and prophylactic therapy for patients at risk for sudden cardiac death due to ventricular fibrillation and ventricular tachycardia. [1] "AICD" was trademarked by the Boston Scientific corporation, so the more generic "ICD" is preferred terminology.
