4.2 Clinical implication of RR interval variability of VT on ICD management.
Since VT regularity is highly reproducible in an episode or in an individual, it could be possible to construct more effective ICD settings according to the RR interval variability of VT (i.e. considering aggressive ATP therapy for regular VTs and extending the VT detection time and initiation of therapy in cases of irregular VTs).
In addition, it could be possible to develop a more effective algorithm based on the variability of the RR interval. Further research is needed for this purpose.
