I48.3
Typical atrial flutter
Clinical Classification Guidelines
Inclusion Terms
- Type I atrial flutter
Medical Intelligence & Overview
Typical atrial flutter, classified under ICD-10 as I48.3, is a type of abnormal heartbeat that originates in the atria, the upper chambers of the heart. It is characterized by rapid, regular heart rhythms due to electrical signals traveling in a reentrant circuit within the right atrium. This condition often affects individuals with underlying heart disease but can occur in healthy hearts as well. Recognized as Type I atrial flutter, it represents a common form of supraventricular tachycardia, which can impact blood flow and overall heart function if not properly managed.
Causes & Symptoms
Clinical Causes: Heart diseases such as coronary artery disease, heart failure, or prior heart surgery High blood pressure (hypertension) Lung diseases like chronic obstructive pulmonary disease (COPD) Thyroid problems, especially hyperthyroidism Alcohol consumption and substance abuse Electrolyte imbalances, including low potassium or magnesium levels Previous episodes of arrhythmia or other heart rhythm disorders Congenital heart defects Stress or intense physical activity Certain medications that influence heart rhythm
Key Symptoms: Palpitations or a fluttering sensation in the chest Shortness of breath, especially during exertion Dizziness or lightheadedness Fatigue or weakness Chest discomfort or pain Feeling of anxiety or unease Rarely, fainting episodes
Diagnostic & Treatment
Diagnosis Path: Diagnosis of typical atrial flutter is generally confirmed through electrocardiogram (ECG), which records the electrical activity of the heart. The characteristic 'sawtooth' pattern seen on ECG, especially in leads II, III, and aVF, helps differentiate atrial flutter from other arrhythmias. Additional tests such as Holter monitoring, echocardiography, or stress testing may be employed to assess overall heart function and identify underlying causes. Electrophysiological studies can also be conducted in some cases to pinpoint the exact location of abnormal electrical circuits within the atria.
Treatment Protocols: Management of typical atrial flutter aims to restore and maintain normal heart rhythm and prevent complications like stroke. Treatment options include:
