Resting systolic blood pressure and heart rate at work.
A random sample (n = 1050) of the population of a region in central Sweden performed a submaximal exercise test on bicycle ergometers. The participants were men and women aged 18 to 65 taking part in the REBUS study 1969-71 (3). This paper deals with the partial relationship between heart rate at different rates of work and systolic blood pressure measured at rest (SBP) controlling the influence of other predictors of heart rate. It was found that the relationship was non-linear and that individuals with a relatively high SBP had a lower heart rate than individuals with lower SBP. The curvilinear relationship was more pronounced in women and grew stronger with increasing rate of work.
