Administration of adenosine in the vein (intravenously) can help medical personnel differentiate between atrial flutter and other forms of supraventricular tachycardia. This leads to the pooling of the blood in the heart and can lead to the formation of blood clots in the heart which poses a significant risk of breaking off and traveling through the bloodstream resulting in strokes.Ī supraventricular tachycardia with a ventricular heart rate of 150 beats per minute is suggestive (though not necessarily diagnostic) of atrial flutter. Similar to the abnormal heart rhythm atrial fibrillation, atrial flutter also leads to poor contraction of the atrial chambers of the heart. But rarely does it persist for months or years.
It is typically not a stable rhythm, and often degenerates into atrial fibrillation (AF). Symptoms may include a feeling of the heart beating too fast, too hard, or skipping beats, chest discomfort, difficulty breathing, a feeling as if one's stomach has dropped, a feeling of being light-headed, or loss of consciousness.Īlthough this abnormal heart rhythm typically occurs in individuals with cardiovascular disease (e.g., high blood pressure, coronary artery disease, and cardiomyopathy) and diabetes mellitus, it may occur spontaneously in people with otherwise normal hearts. Atrial flutter is characterized by a sudden-onset (usually) regular abnormal heart rhythm on an electrocardiogram (ECG) in which the heart rate is fast. When it first occurs, it is usually associated with a fast heart rate and is classified as a type of supraventricular tachycardia. Atrial flutter with varying A-V conduction (5:1 and 4:1)Ītrial flutter ( AFL) is a common abnormal heart rhythm that starts in the atrial chambers of the heart.
