Infants may be at risk of life threatening episodes caused by still unknown factors. The Sudden Infant Death Syndrome (SIDS) is believed to be connected with respiration problems due to immature and developing brain breathing control, and many other factors. Currently heart rate and respiration monitoring is considered of major importance to be applied in the hospital and eventually at hoinc. The objective is accurate detection of bradycardia (heart rate below a selected limit, usually between 80 and 100 beats/min) and apnea (cessation of breathing for more than 20 s). A telemetric instrument was developed for monitoring the heart rate and respiration by extraction of the respiration signal from the electrocardiogram QRS complex peak-to-peak amplitude. It makes use of two electrodes integrated in a transmitter module, thus avoiding use of leads and also reducing artifacts to an acceptable minimum. The receiver station can be a simple detector with apnea and bradycardia alarms, a more complicated recorder or a fully developed signal analyser.
婴儿可能面临由尚不明确的因素导致的危及生命的情况。婴儿猝死综合征（SIDS）被认为与因大脑呼吸控制功能不成熟及仍在发育而出现的呼吸问题以及许多其他因素有关。目前，心率和呼吸监测被认为在医院乃至最终在家庭护理中应用都至关重要。其目标是准确检测心动过缓（心率低于选定限度，通常在80至100次/分钟之间）和呼吸暂停（呼吸停止超过20秒）。一种遥测仪器被开发出来，通过从心电图QRS复合波峰峰值幅度中提取呼吸信号来监测心率和呼吸。它利用集成在发射器模块中的两个电极，从而避免使用导联线，同时也将伪影减少到可接受的最低限度。接收站可以是一个带有呼吸暂停和心动过缓警报的简单探测器、一个更复杂的记录器或一个完全成熟的信号分析仪。
