  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. Acute decompensated heart failure - Wikipedia

    en.wikipedia.org/wiki/Acute_decompensated_heart...

    The treatment of heart disease is rapidly changing and thus new therapies for acute heart failure treatment are being introduced to save more lives from these massive attacks. [24] Bypass surgery is performed by removing a vein from the arm or leg, or an artery from the chest and replacing the blocked artery in the heart. This allows the blood ...

    Torsades de pointes – A type of ventricular tachycardia with a characteristic ECG appearance that can progress to ventricular fibrillation. Ventricular fibrillation (vfib) – Fibrillation of the ventricles is a life-threatening arrhythmia and should be treated by defibrillation and is a medical emergency. Vfib results from uncoordinated ...

  5. Arrhythmia - Wikipedia

    en.wikipedia.org/wiki/Arrhythmia

    Fibrillation can affect the atrium (atrial fibrillation) or the ventricle (ventricular fibrillation): ventricular fibrillation is imminently life-threatening. Atrial fibrillation affects the upper chambers of the heart, known as the atria. Atrial fibrillation may be due to serious underlying medical conditions and should be evaluated by a ...

  6. Cardiogenic shock - Wikipedia

    en.wikipedia.org/wiki/Cardiogenic_shock

    Treatment of cardiogenic shock depends on the cause with the initial goals to improve blood flow to the body. If cardiogenic shock is due to a heart attack, attempts to open the heart's arteries may help. Certain medications, such as dobutamine and milrinone, improve the heart's ability to contract and can also be used.

  7. Primary ventricular fibrillation - Wikipedia

    en.wikipedia.org/wiki/Primary_ventricular...

    12-lead ECG of ventricular fibrillation. 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. In developed countries, PVF is a leading cause of ...

    Less common causes include major blood loss, lack of oxygen, very low potassium, heart failure, and intense physical exercise. A number of inherited disorders may also increase the risk including long QT syndrome. The initial heart rhythm is most often ventricular fibrillation. [55] The diagnosis is confirmed by finding no pulse. [53]

  9. 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] At velocities of 20 miles per ...
