Tilt table testing in childhood: improved sensitivity by non-invasive haemodynamic monitoring devices?
In this study population, BRS and PSA of HRV were able to improve sensitivity of tilt testing after unexplained syncope. Specific BRS or HRV patterns in different mechanisms of neurally mediated syncope could not be identified possibly due to the small sample size.
We were unable to find any clinically useful effect modifiers for patients with acute LBP receiving the McKenzie method.
