MSNA burst frequency and incidence in POTS patients who did and did not become presyncopal during the last 3 min of upright tilt in the EF and ML phases

A and B, burst frequency in non-presyncopal and presyncopal subjects, respectively. C and D, burst incidence in non-presyncopal and presyncopal subjects, respectively. E and F, MAP in non-presyncopal and presyncopal subjects, respectively. There were no differences between phases in MSNA in women who did not become presyncopal; however, MSNA was greater during EF than ML in presyncopal subjects. Error bars indicate the SD.
