Typical atrial flutter
ICD-10 I48.3 is a billable code used to indicate a diagnosis of typical atrial flutter.
Typical atrial flutter is a type of supraventricular tachycardia characterized by a rapid, regular atrial rhythm, typically at a rate of 240 to 340 beats per minute. It arises from a reentrant circuit in the right atrium, often associated with structural heart disease, hypertension, or valvular heart disorders. Clinically, patients may present with palpitations, dyspnea, fatigue, and in some cases, syncope. The anatomy involved primarily includes the right atrium, particularly the cavotricuspid isthmus, which is a common site for the reentrant circuit. Disease progression can lead to complications such as heart failure or thromboembolic events, including stroke, due to the potential for blood stasis in the atria. Diagnostic considerations include an electrocardiogram (ECG) showing characteristic 'sawtooth' patterns of atrial activity (F-waves) and may require further evaluation with echocardiography or electrophysiological studies to assess underlying structural abnormalities. Management typically involves rate control, rhythm control, and anticoagulation therapy to prevent thromboembolic complications.

I48.3 specifically covers typical atrial flutter, which is characterized by a regular atrial rhythm and is often associated with underlying heart conditions. It is differentiated from atypical atrial flutter and other forms of atrial fibrillation.
I48.3 should be used when the patient presents with typical atrial flutter as evidenced by ECG findings of 'sawtooth' F-waves. It is important to differentiate it from paroxysmal or persistent forms based on the duration and pattern of the arrhythmia.
Documentation for I48.3 should include a detailed clinical history, ECG results demonstrating typical atrial flutter, any relevant echocardiographic findings, and treatment plans including anticoagulation and rhythm control strategies.
