Twenty four hour recordings of heart rate and respiration were made on 60 infants with lower respiratory tract infection (LRTI) during the acute phase of the illness, on 20 infants with upper respiratory tract infection (URTI) and on 21 control infants. Infants with LRTI and URTI had more apnoeic episodes of longer than 10 seconds compared with controls. The length of apnoeic episodes was greatest in the LRTI group but their frequency decreased with age. In both the LRTI and URTI groups apnoea was associated with bradycardia but the LRTI group also suffered an appreciable number of episodes of bradycardia without apnoea.
在疾病急性期,对60名患有下呼吸道感染(LRTI)的婴儿、20名患有上呼吸道感染(URTI)的婴儿和21名对照婴儿进行了24小时心率和呼吸记录。与对照组相比,患有LRTI和URTI的婴儿出现了更多持续时间超过10秒的呼吸暂停发作。呼吸暂停发作的时长在LRTI组中最长,但发作频率随年龄降低。在LRTI组和URTI组中,呼吸暂停均与心动过缓相关,但LRTI组也出现了相当数量的无呼吸暂停的心动过缓发作。
