  2. Ventricular fibrillation - Wikipedia

    en.wikipedia.org/wiki/Ventricular_fibrillation

    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]

  3. Cardiac arrest - Wikipedia

    en.wikipedia.org/wiki/Cardiac_arrest

    Cardiac arrest is also identified by a lack of central pulses and abnormal or absent breathing. [1] Cardiac arrest and resultant hemodynamic collapse often occur due to arrhythmias (irregular heart rhythms). Ventricular fibrillation and ventricular tachycardia are most commonly recorded. [14]

    Cardiac arrest. Cardiac arrest is a medical emergency when your heart stops beating suddenly. ... The main cause of cardiac arrest is two types of arrhythmias called ventricular fibrillation or ...

  5. Defibrillation - Wikipedia

    en.wikipedia.org/wiki/Defibrillation

    Within the group of people presenting with cardiac arrest, the specific cardiac rhythm can significantly impact survival rates. Compared to people presenting with a non-shockable rhythm (such as asystole or PEA), people with a shockable rhythm (such as VF or pulseless ventricular tachycardia) have improved survival rates, ranging between 21 and ...

    Unlike cardiac arrest, a heart attack is a circulation problem. When circulation is blocked or cut off in some way and blood is no longer supplied to the heart muscle, this can damage that muscle ...

  7. Commotio cordis - Wikipedia

    en.wikipedia.org/wiki/Commotio_cordis

    Ventricular fibrillation was more easily induced in smaller, leaner animals. [1] The velocity of the impact by a hard object is a critical factor for the onset of commotio cordis: impacts at 40 miles per hour (64 kilometres per hour) were the most likely to cause ventricular fibrillation in an animal model. [1]

  8. Chain of survival - Wikipedia

    en.wikipedia.org/wiki/Chain_of_survival

    Most adults who can be saved from cardiac arrest are in ventricular fibrillation or pulseless ventricular tachycardia, which means their heart has fallen out of rhythm. [14] Early defibrillation is the link in the chain most likely to improve survival since defibrillation can help shock the heart back into a regular beat. [15]

  9. Precordial thump - Wikipedia

    en.wikipedia.org/wiki/Precordial_thump

    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.
