胎儿心率的测量是妇产科临床监护的重要项目之一.人工测量心率的方法是累计一分钟之内心脏搏动次数,由此测得的心率称为平均心率,它表示一分钟之内心脏平均搏动心率.临床上要求仪器测定的是瞬时心率R_f;R_f=1/T_f(次/分),式中T_f是相邻两次胎心搏动的时间间隔,以分为单位.
Fetal heart rate measurement is one of the important clinical obstetrics and gynecology items.Artificial heart rate measurement method is to accumulate a heartbeat within a minute, the heart rate is measured as the average heart rate, which means that within a minute the average heart Pulsatile heart rate. Clinical requirements of the instrument is measured instantaneous heart rate R_f; R_f = 1 / T_f (times / min), where T_f is the interval between two adjacent fetal heartbeats, divided into units.
