Diagnosis often begins with a thorough history and physical examination. Key diagnostic tools include:
Electrocardiogram (ECG): The primary tool for diagnosing dysrhythmias, providing a snapshot of the heart's electrical activity. Holter monitor: A portable device worn for 24-48 hours to capture intermittent dysrhythmias. Event monitor: Similar to a Holter monitor but worn for longer periods, allowing the patient to record events as they occur. Echocardiogram: An ultrasound of the heart to identify structural abnormalities that may contribute to dysrhythmias. Electrophysiological study (EPS): An invasive procedure that maps the heart's electrical pathways to pinpoint the source of the dysrhythmia.
