我在家测量血压时,一条手臂的读数总是更高。这种现象是否正常?

通常,双臂的血压读数存在微小差异是正常的。但差异超过 10 毫米汞柱(mm Hg)就应该引起注意了。此差异可能见于血压读数的顶部数字(收缩压),也可能见于底部数字(舒张压)。

如果手臂间舒张压差异反复超过 10 至 15 mm Hg,血管疾病风险可能增加,心脏病风险也可能随着时间的推移而增加。

手臂间血压测量值差异反复超过 10 mm Hg 可能是某种健康状况的征兆,例如:

  • 手臂血管堵塞,称为外周动脉疾病。
  • 手臂血管之间非典型连接,称为瘘管。
  • 从心脏发出的两条主要血管之间始终有一个开口,称为动脉导管未闭。

如果双臂之间的血压读数有很大差异,请咨询医疗护理专业人员。医疗护理专业人员在将来可能使用血压读数较高的一侧手臂来测量您的血压。
