Objective To observe the effect of lidocaine on heart rate control and the excretion of thyroxine during thyroidectomy in patients with hyperthyroidism. 目的观察甲状腺功能亢进症(甲亢)手术中泵入利多卡因对术中心率增快的控制效果和对甲状腺素分泌变化的影响。
The main program is used for the initiation of the chip, flags polling, events treatment, data calculation, keys treatment, buffers of display refresh and so on. And the function of heart rate control speed is realized based on cardiotach ometer. 主程序主要实现系统初始化、各状态标志位的轮询、事件处理、数据计算、键值处理、显示缓冲区刷新等功能,并在心率计设计的基础上,实现了心率控制(HRC)速度功能。
High-dose β - blockers and tight heart rate control reduce myocardial ischemia and troponin T release in vascular surgery patients 血管外科患者接受大剂量β受体阻断剂及严格心率控制(HRC)治疗可减少心肌缺血及肌钙蛋白T释放
The dual source computed tomography is equipped with two X-ray tubes and two corresponding detectors. With its 83 ms-temporal resolution of single segment reconstruction, high quality coronary artery CT angiography can be acquired without heart rate control. 双源CT具有双球管和双组探测器,其单扇区重建时间分辨率可达83ms,可在不控制心率的情况下获得高质量的冠状动脉血管图像。
A Discussion about How to Through the Method of Heart Rate Control(HRC) Exercise Intensity 用心率测量监控运动训练强度方法的探讨
