背景。居住在欧洲北部强大陆性气候条件下的人群,为适应显著的季节性气温变化及其他气象因素,形成了特有的生理适应机制。分析心脏对这些季节变化的个体反应,对于理解极端气候条件下的生存与适应策略具有重要意义。
目的。基于心率与TP段持续时间的参数,探讨居住在Syktyvkar市的15–16岁青少年在1月与5月期间心脏时频特征之间的关系。
材料与方法。对22名15–16岁青少年在站立位和接受体位变换试验(从站立转为卧位)期间,于1月和5月分别记录 II 导联心电图。基于20个心动周期的记录计算心率和TP段持续时间。数据统计处理采用Excel软件。
结果。对心率和TP段持续时间的群体平均值分析未发现统计学意义上的季节差异。然而,个体数据的深入分析显示,心率和TP段持续时间均存在明显的季节性波动。在冬季,心率对体位变换试验的反应更为显著,最大变化幅度达39%,而5月为23%。TP段持续时间的变化趋势亦类似。个体化分析显示,多数受试者在不同季节表现出心率和TP段的不同程度变化。
结论。结果表明,在评估季节性环境影响时,需采用个体化评估方法。
