  • Heart rate variability (HRV) refers to the beat-to-beat alteration in cardiac cycle length. The objective is to study effect of posture on HRV. Five minutes ECG of children (12 females and 20 males) with mean height 138.88 +/- 11.88 cm, weight 27.66 +/- 5.87 kg and BMI 16.11 +/- 1.38 kg/m(2) were recorded in supine, sitting and standing position. HRV parameters were compared by one-way ANOVA and Bonferroni test. Standing decreases Mean interval between successive RR waves (622.69 +/- 83.24 ms… CONTINUE READING
