Atypical atrial flutter
ICD-10 I48.4 is a billable code used to indicate a diagnosis of atypical atrial flutter.
Atypical atrial flutter is a type of supraventricular tachycardia characterized by a reentrant circuit in the atria, leading to an abnormal heart rhythm. Clinically, patients may present with palpitations, dyspnea, fatigue, or chest discomfort. The anatomy involved includes the atria, particularly the right atrium, where the reentrant circuit often occurs. Disease progression can lead to persistent atrial flutter, which may increase the risk of thromboembolic events, such as stroke, due to potential blood stasis in the atria. Diagnostic considerations include an electrocardiogram (ECG) showing characteristic atrial flutter waves, typically a sawtooth pattern known as 'F-waves.' Additional diagnostic tools may include echocardiography and Holter monitoring to assess the duration and frequency of episodes. Management often involves rate control, rhythm control strategies, and potential catheter ablation for definitive treatment.

I48.4 specifically covers atypical atrial flutter, which is distinct from typical atrial flutter and other arrhythmias. It is characterized by a reentrant circuit and may present with various symptoms including palpitations and fatigue.
I48.4 should be used when the clinical presentation and diagnostic findings confirm atypical atrial flutter, differentiating it from other forms of atrial flutter or atrial fibrillation, which have distinct management and implications.
Documentation should include ECG findings showing atrial flutter waves, clinical symptoms experienced by the patient, and any treatment interventions undertaken. Comprehensive notes on the patient's history and response to treatment are also necessary.
