What is the most common type of supraventricular arrhythmia?

  1. Sinus tachycardia

  2. Atrial flutter

  3. Atrial fibrillation

  4. Focal atrial tachycardias

The correct answer is: Atrial fibrillation

Atrial fibrillation is the most common type of supraventricular arrhythmia. It is characterized by rapid and irregular electrical activity in the atria, leading to an irregular and often rapid heart rate. Atrial fibrillation is a significant health concern due to its association with an increased risk of stroke, heart failure, and other cardiovascular complications. Sinus tachycardia is a normal physiological response to stress, exercise, or certain medications, but it is not considered a type of arrhythmia. Atrial flutter is a type of supraventricular tachyarrhythmia, but it is less common than atrial fibrillation. Focal atrial tachycardias are also a type of supraventricular tachyarrhythmia, but they are less common than atrial fibrillation as well.
