Diagnosis of atrial flutter in neonates typically involves several steps:
1. Clinical Presentation: Symptoms may include rapid heart rate, poor feeding, irritability, or signs of heart failure. 2. Electrocardiogram (ECG): An ECG is the primary diagnostic tool, revealing characteristic saw-tooth flutter waves. 3. Echocardiography: This imaging technique helps assess structural heart abnormalities and cardiac function. 4. Holter Monitoring: Continuous ECG monitoring can capture intermittent arrhythmias that may not be present during a standard ECG.
