Heart rate variability (HRV) is associated with increased cardiac risk factor in several conditions. The iron status of an individual may play an important role in cardiovascular health.
To evaluate heart rate variability in patients with iron deficiency anemia.
Twenty-three patients with iron deficiency anemia (mean hemoglobin (Hb) 8.6+/-2.2 g/dl) and 10 healthy people (mean Hb 13.9+/-1.2 g/dl) were assessed with 24-hour ambulatory Holter recordings during in hospital course having limited physical activity.
Although mean heart rate was significantly higher in patients with anemia, there was no significant difference regarding HRV parameters compared to the healthy group.
There was no significant difference in HRV parameters between patients with iron deficiency anemia with limited physical activity and healthy ambulatory people.
心率变异性（HRV）与多种情况下的心脏风险因素增加有关。个体的铁状态可能在心血管健康中发挥重要作用。
评估缺铁性贫血患者的心率变异性。
在住院期间，23 名缺铁性贫血患者（平均血红蛋白（Hb）8.6+/-2.2 g/dl）和 10 名健康人（平均 Hb 13.9+/-1.2 g/dl）进行了 24 小时动态 Holter 记录，活动量有限。
尽管贫血患者的平均心率明显较高，但与健康组相比，HRV 参数没有显著差异。
在活动量有限的缺铁性贫血患者和健康的活动人群之间，HRV 参数没有显著差异。
