Atrial flutter is an abnormal heart rhythm that is characterized by a rapid but often regular heartbeat. This condition is caused by an overly rapid electrical signal that circulates around the top chambers of the heart, or atria. Although atrial flutter is considered regular, it is still an abnormal rhythm that can cause serious complications if left untreated.
The regularity of atrial flutter occurs because the electrical signal that is responsible for the rapid heartbeat is traveling in a circular pattern around the atria. This circular pattern causes the heart to beat at a very rapid but regular rate. While atrial flutter is considered regular, it is still a dangerous and potentially life-threatening condition.
Atrial flutter can cause symptoms such as palpitations, chest pain, shortness of breath, lightheadedness, and fatigue. If left untreated, atrial flutter can lead to blood clots forming in the heart, which can then travel to the brain, lungs, or other organs and cause a stroke or other serious complications.
Therefore, it is important to recognize the signs and symptoms of atrial flutter and seek medical attention. Treatment for atrial flutter may include medications to control the heart rate, electrical cardioversion to restore the heart's normal rhythm, and medical procedures such as ablation to destroy the abnormal electrical pathways responsible for the condition.
In summary, atrial flutter is an abnormal heart rhythm characterized by a rapid but regular heartbeat. While the regularity of this rhythm makes it appear less dangerous than other arrhythmias, it is still an important condition to recognize and treat to prevent serious complications.
