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).
