【摘要】：目的探讨超重、肥胖儿童及代谢综合征(MS)患儿的心率减速力(DC)、心率加速力(AC)及心率变异性(HRV)差异;体质指数(BMI)与DC、AC、HRV各指标间的相关性。方法选择≥10岁的超重、肥胖儿童103例,其中诊断为MS患儿48例;测定DC、AC、HRV各指标。结果 MS组DC值为(5.97±1.77)ms,低于非MS组的(7.93±1.56)ms;AC值为(-6.78±1.56)ms,高于非MS组的(-8.17±1.61)ms;HF值为335.2 ms~2(157.03~659.33 ms~2),低于非MS组的497.5 ms~2(345.6~767.1 ms~2);BMI为(29.64±2.83)kg/m~2,高于非MS组的(26.79±1.83)kg/m~2,差异均有统计学意义(P0.05)。超重、肥胖儿童BMI与DC呈显著负相关(r=-0.241,P=0.014),与AC呈正相关(r=0.199,P=0.044)。结论 MS患儿的自主神经功能受损,表现为迷走神经张力降低。肥胖程度越高,迷走神经张力越低,机体对心脏的保护力就越差,越易引起心血管疾病的发生。
[Abstract]:Objective to investigate the difference of heart rate deceleration (DC), heart rate acceleration (AC) and heart rate variability (HRV) in overweight and obese children and children with metabolic syndrome (MS), and the correlation between BMI and HRV in DCACA. Methods 103 overweight and obese children aged more than 10 years were selected, 48 of them were diagnosed as MS, and the HRV parameters of DCV ACV were measured. Results DC in MS group was (5.97 卤1.77) Ms, lower than that in non-MS group (7.93 卤1.56) Ms (-6.78 卤1.56) Ms, higher than that in non-MS group (-8.17 卤1.61) Ms HF was 335.2 ms~2 (157.03 卤659.33 ms~2), lower than that in non-MS group (497.5 ms~2 (345.6767.1 ms~2) was (29.64 卤2.83) kgm-2, higher than that in non-MS group (26.79 卤1.83 kg / m-2) (P0.05). The BMI of overweight and obese children was negatively correlated with DC (r = -0.241) and positively correlated with AC (r = 0.199P ~ (0.044). Conclusion the autonomic nervous function of MS children is impaired and the vagal tension is decreased. The higher the degree of obesity, the lower the vagal tension, the worse the body's heart protection, and the more likely to cause cardiovascular disease.
