Objective To analyze the actual application effect of evidence-based nursing in patients with arrhythmia after acute myocardial infarction. Methods 88 patients with acute myocardial infarction complicated with arrhythmia who were admitted to our hospital from July 2024 to July 2025 were selected as the research objects. They were randomly divided into the control group (n=44) and the study group (n=44) by the envelope method. The patients in the control group were given routine nursing, while the patients in the study group were given evidence-based nursing intervention in addition to the routine nursing. The quality of life of the two groups before and after the intervention was compared, and the length of hospital stay and the occurrence of related complications were statistically analyzed. Results Compared with before the intervention, the scores of each dimension of the quality of life of the patients in the study group after the intervention were significantly improved and higher than those of the control group at the same period (P<0.05); the hospital stay of the patients in the study group was shorter than that of the control group, and the incidence of complications was lower than that of the control group (P<0.05). Conclusion Implementing evidence-based nursing intervention for patients with arrhythmia after acute myocardial infarction is conducive to promoting the rehabilitation process of patients, shortening the treatment cycle, and has significant effects on improving the quality of life of patients and reducing the incidence of complications. It is worthy of clinical promotion and application.
