Abstract
A compact, rugged, solid-state heart rate recorder (63 X 94 X 22 mm, 195 g) to measure normal daily heart rates over periods of up to 33 h is described. With an interval switch a selection can be a mean heart rate over 30, 60 or 120 sec. The ECG amplifier filter is equipped with an automatic gain control to eliminate R-wave amplitude changes during physical activity. A continuous acoustic check on correct electrode attachment and sufficient signal amplitude is possible by means of an earphone. Data may be stored on punch tape, tape recorder, or processed on-line, or plotted directly one a line writer to obtain a heart rate profile over the measured time. In 45 studies with adults and children the heart rate recorder has proven to be a reliable instrument.
一个紧凑，坚固耐用，固态心率记录仪(63 X 94 X 22毫米，195克)，以测量正常的每日心率在长达33小时的时间描述。通过间隔开关，可以选择超过30,60或120秒的平均心率。心电放大器滤波器配备了自动增益控制，以消除身体活动期间r波幅度的变化。通过耳机，可以对正确的电极连接和足够的信号幅度进行连续的声学检查。数据可以存储在穿孔纸带、磁带录音机上，或在线处理，或直接在划线机上绘制，以获得测量时间内的心率曲线。在45项针对成人和儿童的研究中，心率记录仪被证明是一种可靠的仪器。
