Effects of diesel exhaust exposure on heart rate. Change from baseline heart rate levels in beats per minute (BPM) during exposure to FA followed by 100, 200, or 400 μg/m3 of DE for eight weeks (D1 – D8) and in the three weeks following that where there was no exposure (P1 – P3). No data was collected for the group exposed to 200 μg/m3 after D8. Data represent the mean +/− SEM. * p-value < 0.05 compared to FA.
