The heart rate is regularly accelerated and then retarded . 心率有规律的加速而后减慢。
2.
Sinus bradycardia occurs when the heart rate falls below 60 . 窦性心动过缓是心率低于60次。
3.
With atropine, ocular effects are accompanied by tachycardia . 用阿托品则产生眼效应，并伴有心率加快。
4.
This period of hypotension is usually associated with bradycardia, decreased pulse pressure, and decreased cardiac output . 在血压降低时期一般伴有心率减慢，脉压降低和心输出量减少。
5.
If the drug accelerates heart rate without improving coronary perfusion, myocardial ischemia will be even more pronounced . 如果此药只加快心率而不改善冠脉灌注，心肌缺血就会更加显著。
