Abstract Objective To explore the clinical application value of critical value reporting of ambulatory electrocardiography (AECG). Methods We enrolled 69 053 patients who had undergone AECG examination in the study, among whom a total of 376 patients with critical value reports were detected. A retrospective analysis was conducted on the detected AECG critical value reports to summarize their clinical application value. Results Out of 376 AECG critical value reports, there were 65 outpatients and 311 hospitalized patients. AECG critical value reports usually occurred in the elderly population aged 60 and above. The incidences of acute coronary syndrome and severe bradycardia were the highest in the five major categories of AECG critical values; among 13 subtypes of AECG critical values, the incidences of suspected myocardial ischemia or injury, and long PP interval of 3-5 seconds were the highest. The incidences of acute coronary syndrome and severe tachyarrhythmia were higher in male patients than those in female patients, while the incidences of severe bradycardia and significantly prolonged QT interval were higher in female patients than those in male patients, all with statistically significant differences (all P<0.05). The reports of the 13 subtypes of AECG critical values mainly originated from the outpatient and neurology departments (inpatient). Conclusion The critical values of AECG are more common in the population over 60 years old, and there are differences in critical value situations between male and female patients. Different management strategies are suggested to be adopted for patients of different sexes. And it is necessary to closely monitor the changes of electrocardiogram among patients in the outpatient and neurology departments.
