Figure 2 Kaplan-Meier survival curves comparing the survival of the different treatment groups described in Table 2. Survival time analysis with each patient survival time (in years) indicated with a symbol at the time of death or when censored alive. (A) NST group (n = 20, filled circles); the monotherapy CDßB group (n = 15, open triangles); and the monotherapy HDßB group (n = 16, filled triangles). (B) Total CDßB group (n = 18) is shown with circles around patients with additional anti-arrhythmic therapy (n = 3); total HDßB group (n = 26) is shown with filled diamonds for patients with additional disopyramide therapy (n = 10). The NST group is shown for reference (filled circles). See Results for statistical comparisons using log-rank t test.
