15 صفحه اولEffects of thoracic blood volume on Valsalva maneuver.
The Valsalva maneuver (VM) is frequently used to test autonomic function. However, the VM is also affected by changes in blood volume and blood volume redistribution.

Larger blood volume shifts in some normovolemic individuals may be sufficient to induce decreases in blood pressure (BP) that pr...
متن کاملEffect of Valsalva Maneuver on QT Dispersion in Hemodialysis Patients.
Increased QT dispersion seems to be related to an increased risk of arrhythmia and sudden death, a common cause of mortality in hemodialysis (HD) patients. Increase in sympathetic tone has been documented in HD patients. In this study, we aimed to investigate the effect of changes in the autonomic tone on QT dispersion (QTd) in HD patients. Twenty HD patients (M/F 13/7; age, mean ±SD, 28 ± 10 y...
