Atrial flutter is a type of supraventricular tachycardia (SVT) that is characterized by an abnormal, rapid electrical circuit in the atria of the heart. It typically causes the heart to beat at a rate of 200-400 beats per minute, which is significantly faster than the normal resting rate of 60-100 beats per minute.
Atrial flutter is a type of SVT because it involves the heart's electrical system and causes the heart to beat in an abnormal rhythm. Unlike atrial fibrillation, which involves chaotic electrical activity in the atria, atrial flutter is caused by a single, rapid electrical circuit in the atria that causes the heart to beat at a rapid rate.
Atrial flutter is usually treated with medication or electrical cardioversion, which involves applying a shock to the chest to reset the heart's rhythm. In some cases, the abnormal rapid rhythm can be converted into a normal sinus rhythm through medication or electrical cardioversion, while in other cases, the abnormal rhythm persists and requires ongoing treatment.
Atrial flutter is an important condition to be aware of because it can lead to serious complications such as stroke and heart failure if left untreated. It is important to seek medical attention if you experience any symptoms of atrial flutter, such as palpitations, shortness of breath, chest pain, or fatigue.
