Patients‘ characteristics
All 100 patients were enrolled in the study according to specific inclusion and exclusion criteria. The average number of recorded points was 4580±1035 (interquartile range; IQR 2466-7711). Of the 100 patients, the ACZ was observed in 95 patients (95%), and the ACZ was linearly distributed (Figure 1 ). To investigate the characteristics of patients with ACZ, we divided all patients into two groups as follows: non-ACZ group (n=5) and ACZ group (n=95). Patients‘ characteristics are listed in Table 1 . All five patients in the non-ACZ group had PAF. Patients in the ACZ group had significantly elevated body mass index (BMI), higher prevalence of hypertension, and larger LA diameter/BSA than those in the non-ACZ group. Baseline medication therapy and the other TTE findings did not differ between the non-ACZ group and the ACZ group.
