    Cardioversion should not be performed without adequate anticoagulation in patients with more than 48 hours or unknown duration of AF. Anticoagulation is adequate if warfarin is given with target INR between 2 and 3 for three to four weeks prior to cardioversion, and continued for at least four weeks after cardioversion. [60]

  3. Atrial fibrillation - Wikipedia

    en.wikipedia.org/wiki/Atrial_fibrillation

    Atrial fibrillation (AF, AFib or A-fib) is an abnormal heart rhythm (arrhythmia) characterized by rapid and irregular beating of the atrial chambers of the heart. [11][12] It often begins as short periods of abnormal beating, which become longer or continuous over time. [4] It may also start as other forms of arrhythmia such as atrial flutter ...

  4. Cardioversion - Wikipedia

    en.wikipedia.org/wiki/Cardioversion

    Cardioversion is a medical procedure by which an abnormally fast heart rate (tachycardia) or other cardiac arrhythmia is converted to a normal rhythm using electricity or drugs. Synchronized electrical cardioversion uses a therapeutic dose of electric current to the heart at a specific moment in the cardiac cycle , restoring the activity of the ...

  5. Defibrillation - Wikipedia

    en.wikipedia.org/wiki/Defibrillation

    Defibrillation. 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. Although not fully understood, this process depolarizes ...

  6. Arrhythmia - Wikipedia

    en.wikipedia.org/wiki/Arrhythmia

    [22] [23] A Holter monitor is an EKG recorded over a 24-hour period, to detect arrhythmias that may happen briefly and unpredictably throughout the day. [citation needed] A more advanced study of the heart's electrical activity can be performed to assess the source of the aberrant heart beats.

  7. Wearable cardioverter defibrillator - Wikipedia

    en.wikipedia.org/wiki/Wearable_cardioverter...

    A wearable cardioverter defibrillator (WCD) is an external device with a built-in defibrillator. The WCD is worn directly on the body by patients who are at transient risk for sudden cardiac death (SCD) for short-term risk mitigation and it does not require surgery for use. A WCD is also a temporary therapeutic option in case an implantable ...

    The patient will probably feel fine within 8 to 12 hours after the procedure, but may feel a small pinch at the insertion site. After a short period of general rest, the patient may resume some minor activity such as gentle, short, slow walks after the first 24 hours. If stairs must be climbed, they should be taken one step at a time and very ...

  9. Holiday heart syndrome - Wikipedia

    en.wikipedia.org/wiki/Holiday_heart_syndrome

    Holiday heart syndrome, also known as alcohol-induced atrial arrhythmias, is a syndrome defined by an irregular heartbeat and palpitations [1] associated with high levels of ethanol consumption. [2] Holiday heart syndrome was discovered in 1978 when Philip Ettinger discovered the connection between arrhythmia and alcohol consumption. [3]
