Table 2. Number of patients shocked (PS) and cumulative success rate (CSR) at each ECV shock for patients (AF+AFL) grouped to BTE waveforms (PE and LE). The values are reported as % (number of patients N). The last shock delivered is a monophasic shock (MS). Both groups (PE and LE) are compared with Model 1 and Model 2, reporting their respective OR [95% CI].

*OR were not assessed for PS 4 due to the too small sample size.
