结果发现非起搏心率较高的患者出现死亡或心衰住院等主要终点的风险更高（p<0。
Higher intrinsic (unpaced) HR was associated with greater risk of achieving the primary end point of death or heart failure hospitalization (P<0.001).
它持续监测心跳节律，如果心跳过慢就像起搏器一样发挥作用，如果出现室速或室颤它就会发射不同能量的除颤电流，使心率恢复正常。
The ICD continuously monitors your heart rhythm. If it detects a rhythm that's too slow, it paces the heart as a pacemaker would.
利多卡因一般在预防室性心律失常是无效的，就像心脏起搏或阿托品对心率增加没有帮助一样。
Lidocaine is generally ineffective in preventing ventricular arrhythmias, as is cardiac pacing or atropine to increase the heart rate.
大部分起搏器有感受装置，当心率超过一定水平时自动关闭，当心率过慢时打开，这叫做按需式起搏器。
Most pacemakers have a sensing device that turns itself off when the heartbeat is above a certain level. It turns back on when the heartbeat is too slow.
比较心脏起搏器治疗前心气虚证、心血虚证症候积分与CO、心率的相关性。
The difference of the syndrome manifestation scores on the heart Qi-deficiency and the heart Blood-deficiency and co, HR before treatment of heart pacemaker.
比较心脏起搏器治疗前心气虚证、心血虚证症候积分与CO、心率的相关性。
The difference of the syndrome manifestation scores on the heart Qi-deficiency and the heart Blood-deficiency and co, HR before treatment of heart pacemaker.
