Authors: Hong-yan Yang, Fang-fang Zhang, Ru Liu, Zhong-Jian Li




 

Aims: To explore the ECG changes of malignant tumor patients before and after treatment, thus provide basis for clinical treatment.

 

Method: We chose 7201 malignant tumor patients with chemotherapy or radiation therapy in Chenzhou No.1 People’s Hospital from June to December during 2011 as the study subject(Group 1),including 4343 males and 2858 females,the age ranged from 13 to 90 years old , analyzed and compared the ECG results before and after the treatment, at the same time we choose 7200 non-malignant tumor patients as control group(Group2), including 3477 males and 3723 females, the age ranged from 1 to 95 years old, compared the ECG results of the two groups before treatment,then analyzed the ECG results of the malignant tumor group before and after the treatment.

 

Results: The abnormal rate of ECG between the two group was statistically significant (P < 0.05). The abnormal rate of ECG in the malignant tumor group before and after the treatment was also statistically significant (P < 0.05). The abnormal ECG includede cardiac arrhythmia, ST - T changes and low QRS voltage.

 

Conclusion: The ECG changes of malignant tumor and the non-malignant tumors and malignant tumor patients before and after treatment is due to the damage of primary malignant tumor , chemotherapy or radiation therapy on myocardial directly or indirectly, nutrition and a lack of energy and so on. So we should prevent organ damage in the treatment of malignant tumor as early as possible to maintain and support a healthy heart.
