Electrical Remodeling of Ventricular Repolarization Abnormality after Treatment in Pheochromocytoma: U Wave Finding in a Retrospective Analysis

Figure 3

Correlation between U wave amount and levels of urinary metanephrine, 3-methoxytyramine and tumor size and reduction of U wave after surgery treatment. (a) Concentrations of urinary metanephrine plotted against number of U wave. (b) Concentrations of urinary 3-methoxytyramine plotted against U wave amount. (c) Tumor size plotted against U wave amount. (d) Reduction of U wave amount after surgery in each patients. Linear regression was performed in (a), (b),and (c) plots, and the r² value was shown for each analysis. Wilcoxon signed rank test was performed in (d) plot, and the p value was shown.
