目的总结近年来儿童急性白血病诊治过程的心电图情况并加以分析。方法收集血液病房和门诊经骨髓细胞学检查确诊的白血病患者,对患者进行治疗前、诱导缓解期末、巩固治疗期末和治疗后4个时期所进行的心电图进行统计,了解异常的心电图的发生情况,进一步确认并了解其心功能的损害。结果在儿童白血病治疗过程中,异常心电图发生率为30.9%,其中以诱导缓解期末发病率最高,发病率为45.7%。诱导缓解期末与治疗前和治疗后相比,差异有统计学意义(P>0.05)。结论对白血病患者诱导缓解期治疗时应加大对心功能的保护,并及时进行心电图监测。 Objective To summarize and analyze the situation of electrocardiogram in diagnosis and treatment of childhood acute leukemia in recent years. Methods Patients with leukemia diagnosed by bone marrow cytology in blood wards and outpatients were collected and the electrocardiogram was performed before treatment, at the end of induction remission, at the end of consolidation treatment and at 4 post-treatment periods to understand the occurrence of abnormal ECG, To further confirm and understand the damage of their cardiac function. Results During the treatment of childhood leukemia, the incidence of abnormal ECG was 30.9%, of which the incidence of induction remission was the highest, the incidence rate was 45.7%. Compared with before treatment and after treatment, the difference was statistically significant (P> 0.05). Conclusion The protection of cardiac function should be increased in patients with leukemia induced remission and timely monitoring of ECG.
