Atrial fibrillation (AF) patients can present with a range of symptoms, but these are a poor guide to diagnosis.
AF patients may present with heart failure, myocardial infarction or another ACS, stroke or haemodynamic collapse and a variety of other, typically, non-specific symptoms (Figure 7).32
However, 12% to 33% of AF patients are asymptomatic.19,2 On the other hand, AF patients often experience debilitating symptoms despite treatment (Figure 8).2
Women tend to be develop more frequent and severe AF symptoms than men. For instance, women show longer paroxysmal episodes. Moreover, the ventricular response rates during paroxysmal episodes are faster in women than among men.6
The European Society of Cardiology (ESC) and the European Heart Rhythm Association (EHRA) guidelines recommend using the modified EHRA symptom scale (Table 4) to quantify the symptomatic burden in clinical practice.5 However, their non-specific nature makes symptoms alone an unreliable guide to diagnosis, the topic of the next section.
