Figure 1 Flow diagram describing the relationship between the two study groups (ICD and conventional) and the entire MADIT II population. Heart Rhythm 2009 6, 180-186DOI: (10.1016/j.hrthm.2008.10.045) Copyright © 2009 Terms and Conditions
Figure 2 Kaplan-Meier curve showing time until the experience of an appropriate ICD therapy for VT or VF as a function of QTVN in the top quartile (high risk) for men and women compared with the bottom three quartiles. Men in the high-risk quartile had a significantly shorter time until VT/VF compared with those in the low-risk quartile (P = .001), while there was no difference between the groups among women.

Figure 3 Kaplan-Meier curve showing time until the experience of an appropriate ICD therapy for VT or VF as a function of QTVI in the top quartile (high risk) for men and women compared with the bottom three quartiles. Men in the high-risk quartile had a significantly shorter time until VT/VF compared with those in the low-risk quartile (P = .008), while there was no difference between the groups among women.

Figure 4 Kaplan-Meier curve showing time until the experience of an appropriate ICD therapy for VT or VF as a function of coherence in the bottom quartile (high risk) for men and women compared with the top three quartiles. Women in the high-risk quartile had a significantly shorter time until VT/VF compared with those in the low-risk quartile (P = .024), while there was no difference between the groups among men.
