Comparison of event rate between study and reference period
The number of patients that suffered from any arrhythmic event did not differ significantly from that of the reference period (χ2 = 1.09, p = 0.29). A comparable rate of VT, VF, ATP and shocks was also found (see Table 2).
The overall mean event number per person during the timeframe of the study was 0.19 events/person, not significantly higher than 0.15 events/persons in the reference period (difference 0.04, p = 0.36).
