Atrial Flutter

Atrial Flutter is a type of abnormal heart rhythm that originates in the atria, the upper chambers of the heart. It is characterized by rapid, organized electrical impulses that cause the atria to beat faster than normal, usually at a rate of 200 to 350 beats per minute. This results in inefficient atrial contraction and may cause symptoms like palpitations, dizziness, fatigue, or shortness of breath.
