Abstract 25: Accuracy of Patient Identification of Atrial Fibrillation in the Clinic Setting

Background: Atrial fibrillation (AF) related symptoms are commonly reported but often difficult to directly correlate with arrhythmia. Given that symptoms largely drive management, correct patient awareness of AF is critical to implementation of appropriate therapy. Objective: To determine accuracy of patient identification of their own atrial rhythm. Methods: All AF patients in our center undergo patient reported outcome assessment with the Toronto AF Severity Scale (AFSS) immediately prior to clinic visit. Using the validated questions from the AFSS, we assessed if patients were able to accurately determine their rhythm (AF or not) compared to an electrocardiogram (ECG) during the same clinic visit. Results: We identified 254 unique patients (Table 1) with interpretable ECG and AFSS data available from the same visit. Based on ECG, 81% (n=206) were not in AF. 20 of these 206 patients (9.7%) incorrectly identified themselves in AF (Figure 1). Patients who incorrectly thought they were in AF were signific...
