Key result
Visual reaction time was significantly slower during the middle of the cardiac cycle compared to earlier in the cycle, but this effect was not more pronounced among individuals at increased risk for hypertension.

Does cardiac cycle phase (baroreceptor stimulation) affect visual reaction time in normotensive individuals at varying risk for hypertension?

Baroreceptor effects on reaction time appear hypertension-risk independent; leaves open clinical relevance and requires prospective validation.

Does cardiac cycle phase (baroreceptor stimulation) affect visual reaction time in normotensive individuals at varying risk for hypertension?
Baroreceptor stimulation during the middle of the cardiac cycle impairs sensorimotor functioning (reaction time) in normotensive individuals, regardless of their underlying risk for developing hypertension.
Stewart et al. (2006) conducted a cross-sectional in Varying risk for hypertension (n=93). Baroreceptor stimulation during the middle of the cardiac cycle vs. Early in the cardiac cycle (reduced baroreceptor stimulation) was evaluated on Visual reaction time. Visual reaction time was significantly slower during the middle of the cardiac cycle compared to earlier in the cycle, but this effect was not more pronounced among individuals at increased risk for hypertension.
