Palpitation score, HADS score, and the correlations between them
The medians of the participants’ palpitation score, HADS-A score, and HADS-D score were 3 (IQR, 2-4), 9.5 (IQR, 6.75-14), and 8 (IQR, 5-10.25), respectively. Among the 22 patients, 15 (68.2%) had anxiety symptoms (HADS-A ≥ 8), and 13 (59.1%) had depression symptoms (HADS-D ≥ 8) (Table 1). Patients with anxiety symptoms (HADS-A ≥ 8) were associated with higher palpitation score when compared with those without anxiety (median [IQR], 3 [3-4] vs 2 [1-3],P =0.01) (Figure 4A). Similarly, the palpitation score was also significantly higher in patients with depression (HADS-D ≥ 8) than those without depression (median [IQR], 3 [3-4.5] vs 2 [1-3],P =0.02) (Figure 4B). In addition, both HADS-A score (r=0.609; 95% CI, 0.25-0.82; P <0.01) and HADS-D score (r =0.516; 95% CI, 0.12-0.77; P =0.01) were positively related to palpitation score (Figure 5A-B).
