Atrial flutter is a common cardiac arrhythmia that is characterized by a rapid, organized rhythm of the atria of the heart. This rhythm is produced by abnormal electrical impulses in the atria, which can cause the heart to beat at a rate of up to 400 beats per minute (bpm). The most common type of atrial flutter is called “type I,” which is characterized by a regular, rapid atrial rate of 250-400 bpm.
Atrial flutter is usually caused by an underlying structural issue in the heart, such as a congenital heart defect or scarring from a prior heart attack or surgery. It can also be triggered by certain medications, alcohol, and drugs. When atrial flutter occurs, the heart pumps inefficiently and can cause symptoms such as chest pain, shortness of breath, fatigue, and lightheadedness.
It is important to note that atrial flutter is not the same as atrial fibrillation, which is a more serious arrhythmia that can cause a much higher heart rate of up to 400 bpm. Atrial flutter is generally considered less dangerous than atrial fibrillation and is usually treated with medications or other therapies to restore a normal heart rhythm.
In summary, atrial flutter is a common cardiac arrhythmia that can cause the heart to beat at a rate of up to 400 bpm. It is usually caused by an underlying structural issue in the heart and can be treated with medications or other therapies to restore a normal heart rhythm. It is important to note that atrial flutter is not the same as atrial fibrillation, which can cause a much higher heart rate.
