本组15例急性 CO 中毒病人,男7例女8例,14例属中度到重度中毒,只有一例发觉较早而未昏迷,年令范围18～73岁。10例是在中毒好转后自觉心悸、胸闷等症状而描记心电图的,5例自昏迷起描记心电图。由于急性 CO 中毒病人在昏迷时和清醒后的心电图改变都较明显,且彼此间无显著差别,故皆以首次心电图的改变列表说明如下说明:(1)器质性室性早跳指此例室性早跳的 QRS 波宽达0.14秒,R 波有切迹且振幅<15毫米;(2)QTc 延长:QTc>0.44;(3)T 波异常中,6例左胸导联 T 波高尖对称,其中5例昏迷病人,清醒后4例 T 波转为倒置。总之,15例以 T波异常的发生率最高,其次是 QTc 延长和心率的增快。介绍二例如下:
The group of 15 patients with acute CO poisoning, 7 males and 8 females, 14 cases of moderate to severe poisoning, only one case found earlier without coma, the annual range of 18 to 73 years old. 10 cases were improved after poisoning palpitations, chest tightness and other symptoms while describing the ECG, 5 cases of ECG from the coma. Because of acute CO poisoning patients in coma and awake after the ECG changes are more obvious, and no significant difference between each other, it is the first list of changes in ECG instructions as follows: (1) organic ventricular premature jump refers to this example (2) QTc prolongation: QTc> 0.44; (3) In T-wave abnormalities, 6 cases of left chest lead T-wave tip Symmetry, including 5 cases of coma patients, 4 cases of awake after T wave into inversion. In conclusion, 15 cases had the highest incidence of T wave abnormalities, followed by QTc prolongation and heart rate increase. Two examples are as follows:
