Heart rate (calculated beat to beat) and excursions of the thoracic wall were registered continuously during exchange transfusions in the newborn period (N equals 29). Short time changes of heart rate ranging from 5 to 10 (N equals 11) and from 11 to 25 beats per minute (N equals 11) were usually present before exchange transfusion. In two cases "silent" (i.e. short time changes of heart rate lower than 5 bpm) heart rate pattern was registered before and in another two cases appeared during the exchange transfusions. This pattern is of prognostic value, 3 of these 4 children showed severe complications during the therapeutic procedure. Of particular interest is, that the "silent" pattern could be detected before other clinical signs of shock appeared. Monitoring heart frequency (beat to beat) therefore gives the possibility to start the therapy of complications early.
在新生儿期进行换血治疗期间（N = 29），持续记录心率（逐搏计算）和胸壁运动。换血治疗前，通常会出现心率短时间变化，变化范围为每分钟5至10次（N = 11）和每分钟11至25次（N = 11）。有两例在换血治疗前记录到“安静型”（即心率短时间变化低于5次/分钟）心率模式，另有两例在换血治疗期间出现该模式。这种模式具有预后价值，这4名儿童中有3名在治疗过程中出现了严重并发症。特别值得关注的是，在休克的其他临床体征出现之前就能检测到“安静型”模式。因此，监测心率（逐搏）能够尽早开始并发症的治疗。
