Description
AF: Atrial Fibrillation;
a: EHRA IIa and IIb can be distinguished by assessing whether AF symptoms affect the patient's function. The most common AF-related symptoms are fatigue/exhaustion, exertional dyspnea, or less commonly, palpitations and chest pain.
To facilitate follow-up of AF patients, the severity of AF symptoms is quantified internationally using the EHRA score.
