Figure 1From: Initial description of changes in wall motion parameters in normal subjects undergoing rest/regadenoson stress using a tagged MRI sequenceAverage change in ventricular twist between ES and ED per slice location. Errors bars are ± standard deviation. Negative values indicate clockwise rotation (CW), positive values indicate count-clockwise rotation (CCW). P-Values with bars are for between slice student's t-test comparisons (rest and stress respectively), P-values without are for within slice comparison between rest and stress with alpha = 0.05.Back to article page
