Changes in BP, HR, and delta index during the active standing test. Comparison of the active standing test results in the BT(+) and BT(-) groups. (A1-C1) indicates absolute change (mean ± standard error of the mean); (A2-C2) indicates changes compared with the supine position (mean ± standard error of the mean); (D) indicates the changes in the BT criteria. Abbreviations: BP, blood pressure; BT, blunted tachycardia; HR, heart rate. x-axis: supine, mean value of the supine position, 1–15 min after standing
