本文回顾分析安置心脏起搏器患者的动态心电图(DCG)记录。以观察在心率固定状态下的Q—T间期是否存在变化。有25例患者的44份记录符合下列条件:(1)动态记录时间足24小时,(2)全部为起搏心律。44份DCG中,19份记录于未服任何药物时,25份记录于服药期间。分别于0、4、8、12、16、20时复录心电图并测量Q～T间期。结果发现:(1)未服药组与服药组的Q—T间期在24小时6个时刻测值差异均无显著性,(2)睡眠与清醒两种状态的Q—T间期其测值无显著性。表明心率固定时Q—T间期无明显昼夜变化。(3)老年人与中、青年人在各时的Q—T间期值差异无显著性。表明不同年龄组Q—T间期无明显日内变化。(4)基础情况无明显改变的5例患者,间隔5～7天复录DCG,其Q—T间期测值极为相近,表明Q—T间期日间差异极少。(5)服用
This article reviews the analysis of ambulatory electrocardiogram (DCG) recordings in patients with pacemakers. To observe whether there is a change in the Q-T interval at a fixed heart rate. Forty-four records of 25 patients met the following criteria: (1) dynamic recording time was 24 hours, and (2) all were paced rhythm. Of the 44 DCGs, 19 were recorded when no medication was taken and 25 were recorded during the medication period. At 0, 4, 8, 12, 16, and 20 respectively, electrocardiogram was recorded and the Q ~ T interval was measured. The results showed that: (1) There was no significant difference in the Q-T interval between the non-medication group and the medication group at 24 hours and 24 hours; (2) The Q-T interval between sleep and awake No significant. That heart rate Q-T fixed period without significant diurnal changes. (3) There was no significant difference in Q-T value between the elderly and middle-aged and young people at all times. Show that different age groups Q-T interval no significant intraday changes. (4) Among the 5 patients who had no significant changes in their basic conditions, DCG was reproduced from 5 to 7 days apart. The Q-T interval was very similar, indicating very little difference between days in Q-T interval. (5) taking
