Heart rates of beaver (Castor canadensis) under free-ranging captive conditions for active behaviors and resting in water (approximately 121 beats/min) were significantly (P less than 0.01) higher than for resting on land (100 beats/min). 2. Although no transient recovery tachycardia was evident in swimming heart rates following diving, average swimming heart rates were higher (127 beats/min) after diving than after other precursor behaviors (123 beats/min). 3. Beaver exhibited bradycardia when sleeping (75 beats/min), diving (61 beats/min), and when threatened on land (57 beats/min). 4. The respiratory sinus arrhythmia indicated a respiratory rate of 15 breaths/min. 5. Cold temperatures (approximately 0 degree C) elicited higher heart rates than did warmer temperatures (approximately 20 degrees C) in active, non-diving behaviors (P less than 0.05).

在自由放养的圈养条件下，海狸（加拿大海狸）在进行活跃行为以及在水中休息时的心率（约121次/分钟）显著（P小于0.01）高于在陆地上休息时的心率（100次/分钟）。2. 尽管潜水后游泳心率中未出现明显的短暂恢复性心动过速，但潜水后的平均游泳心率（127次/分钟）高于其他前驱行为后的平均游泳心率（123次/分钟）。3. 海狸在睡眠时（75次/分钟）、潜水时（61次/分钟）以及在陆地上受到威胁时（57次/分钟）会出现心动过缓。4. 呼吸性窦性心律不齐表明呼吸频率为15次/分钟。5. 在活跃的非潜水行为中，低温（约0摄氏度）比温暖温度（约20摄氏度）引发更高的心率（P小于0.05）。
