The symptoms of atrial flutter relate to tachycardic heart rate either causing palpitations or decreased overall cardiac output (from loss of atrial contraction and fast ventricular rates ...

Atrial flutter is similar to atrial fibrillation (AF) in regard to symptoms and thromboembolic risk, including stroke. However, the pathophysiology and management differ. Symptoms of AF reflect ...

Therefore, the rhythm is atrial flutter with 2:1 AV block. Importantly, the only supraventricular rhythm with an atrial rate > 260 beats/min (up to 320 beats/min) is typical atrial flutter.
