MSNA responses to upright tilt during the EF and ML phases

MSNA (A) burst frequency, (B) burst incidence and (C) total activity of POTS patients during supine and passive upright tilt at 60 deg in the EF and ML phases. Data are presented using the last stable data carry forward method for subjects who experienced presyncope. 1, 2, 3, 4, 5 indicate early minutes of tilting; 10, mean from 7–10 min; 20, mean from 17–20 min; 30, mean from 26–29 min; 40, mean from 36–39 min; 45, mean from 42–45 min. Error bars indicate the SD. There were no differences between phases in the MSNA response to upright tilt.
