EHRA Symptom Score (AF Severity Class) Calculator

EHRA Symptom Score (AF Severity Class): Explanation and Clinical Context The EHRA (European Heart Rhythm Association) symptom score is a standardized tool to quantify the severity of symptoms in patients with atrial fibrillation (AF). It categorizes patients based on the impact of AF-related symptoms on daily activities. The score ranges from EHRA I (asymptomatic) to EHRA IV (disabling symptoms), allowing clinicians to assess symptom burden, guide treatment strategies, and monitor therapeutic efficacy.

EHRA Classes: - EHRA I: No symptoms - EHRA II: Mild symptoms, normal daily activity not affected - EHRA III: Severe symptoms, normal daily activity affected - EHRA IV: Disabling symptoms This tool is widely used in clinical practice and clinical trials to standardize symptom assessment in AF patients, supporting decisions for rate or rhythm control interventions.
