氯胺酮注射后有心率增速,窦房结传导时间延长趋势(但无统计学意义);而窦房结恢复时间、校正窦房结恢复时间及窦房结恢复时间指数均明显延长(P值分别小于0.01,0.01及0.05);P-R间期无改变。r-羟基丁酸注射后有心率减慢倾向(但无统计学意义),窦房结传导时间明显缩短(P<0.01);窦房结恢复时间缩短虽不显著,而校正窦房结恢复时间及窦房结恢复时间指数明显缩短(P<0.05及0.01):P-R间期亦无改变。为此作者等认为:对
After ketamine injection, heart rate increased and conduction time of sinus node prolonged (but not statistically significant); while the recovery time of sinus node, the time to correct sinus node recovery and the recovery time of sinus node were significantly prolonged Less than 0.01, 0.01 and 0.05), no change in PR interval. The heart rate slowed down (but not statistically significant) after injection of r-hydroxybutyrate, and the conduction time of the sinus node was significantly shortened (P <0.01). Although the recovery time of sinus node was shortened, the recovery time of sinus node And sinus node recovery time index was significantly shorter (P <0.05 and 0.01): PR interval also did not change. For this reason the author thinks: yes
