Atrial flutter

Definition

Atrial flutter is a type of supraventricular tachycardia characterized by rapid, regular atrial contractions. It results in a sawtooth pattern on an ECG and can lead to serious complications if untreated.

5 Must Know Facts For Your Next Test

1. Atrial flutter involves the atria beating at a rate of 240-400 beats per minute.
2. It often leads to symptoms such as palpitations, shortness of breath, and dizziness.
3. The condition can increase the risk of stroke due to the formation of blood clots in the atria.
4. Common treatments include cardioversion and the use of antidysrhythmic drugs like amiodarone or beta-blockers.
5. Diagnosis is typically confirmed through an electrocardiogram (ECG), which shows a characteristic sawtooth pattern.
