Electrocardiograms were recorded hourly for five days in 16 caged Macaca fascicularis by means of a miniaturized ECG transmitter connected to two chest leads. The lowest heart rates were 135 +/- 35 (mean +/- SD, n= 31) beats/min at 5 a.m., and the highest were 192 +/- 22 (n = 29) beats/min at 3 p.m. Sinus arrhythmia was common. Eight of the animals were trained to exercise in a specially designed enclosed treadmill; their heart rates were recorded daily during two 10-min periods of running at 3.4 km/h. Transfer of the monkeys (n k0) to the treadmill increased heart rate from 186 +/- 24 to 228 +/- 23 beats/min; exercise further increased it to 271 +/- 8 beats/min.
通过连接到两个胸部导联的小型心电图发射器,对16只关在笼中的食蟹猕猴连续五天每小时记录一次心电图。最低心率出现在凌晨5点,为135±35(平均值±标准差,n = 31)次/分钟,最高心率出现在下午3点,为192±22(n = 29)次/分钟。窦性心律失常很常见。其中8只动物经过训练,在专门设计的封闭式跑步机上运动;在以3.4公里/小时的速度跑步的两个10分钟时间段内,每天记录它们的心率。将猴子(n = 8)转移到跑步机上时,心率从186±24次/分钟增加到228±23次/分钟;运动进一步将心率提高到271±8次/分钟。
