Abstract Objective: To investigate the clinical value of 24h dynamic electrocardiogram [heart rate variability (HRV), QT interval variability (QTV)] combined with the neutrophil lymphocyte ratio (NLR) in predicting malignant arrhythmia after acute myocardial infarction (AMI). Methods:96 patients with AMI (AMI group) who were admitted to cardiology department in the hospital from August 2014 to August 2018 and 60 normal volunteers (control group) who underwent physical examination in the hospital during the same period were included in the study. Patients in AMI group were divided into the malignant group (38 cases) and the non-malignant group (58 cases) according to the occurrence of malignant arrhythmia. All subjects were given 24h dynamic electrocardiogram examination. Changes of HRV , QTV and NLR value were monitored and compared. The value of HRV, QTV indicators and NLR values in predicting the occurrence of malignant arrhythmia was analyzed by receiver operating characteristic (ROC) curve. Results:The values of SDNN, SDNN-index, SDANN-index, rMSSD, 24h-QTV, Day-QTV, Night-QTV and NLR in AMI group were significantly lower than those in the control group (P<0.05). Except rMSSD, the values of SDNN, SDNN-index, SDANN-index, 24h-QTV, Day-QTV, Night-QTV and NLR in the malignant group were significantly lower than those in the non-malignant group (P<0.05). ROC curve analysis indicated that the value of HRV and QTV indicators combined with NLR values in predicting the occurrence of malignant arrhythmia after AMI was greater, and the area under ROC curve was the largest (0.892). Conclusion: HRV and QTV indicators combined with NLR values can predict the occurrence of malignant arrhythmia after AMI.
