Atrial fibrillation medications

Fast, chaotic contraction of the atria is the most common arrhythmia and is represented by atrial fibrillation. Atrial fibrillation is rare before the age of 60 years, but is found in 6-8% in 70 years of age, and in 10% of 80 year olds. Wear and tear on the heart makes the condition occur in older people.

During atrial fibrillation, the electrical activities of the atria are not coordinated. The atria beats so fast 300-600 beats per minute, that the seemingly shaking (fibrillerer) fortunately, when not all of these atrieimpulsene forward to the ventricles. AV node between the atria and ventricles work as a door opener, and it allows only a fraction of impulses through. Nevertheless, some additional impulses reach the ventricles. This means that atrial fibrillation can increase your heart rate to 150 beats per minute or more. In addition to the ventricles atrieimpulsene arrive at inconsistent intervals, resulting in an irregular pulse.

atrial fibrillation guidelines

Atrial fibrillation may come as seizures and last from minutes to hours or days or more before it switches to a regular rhythm (sinus rhythm). Atrial fibrillation can also be chronic and be a continuing problem.

Atrial fibrillation is rarely life-threatening arrhythmia, but over time it can cause other serious conditions such as stroke.

Classification of tachycardias

  • In the atria

  1. Atrial fibrillation
  2. Atrial flutter
  3. Supraventricular tachycardias
  4. Wolff-Parkinson-White syndrome (WPW)

  • The ventricles

  1. Ventricular tachycardia
  2. Ventricular fibrillation
  3. Long QT syndrome
