Inclusion criteria
Inclusion criteria: 1. Retrospective study: The patients who visited our hospital and underwent electrocardiogram (ECG) more than twice from January 2015 to May 2023 were selected as the research subjects. According to whether atrial fibrillation was detected in the second examination, they were classified into two categories: the normal group and the atrial fibrillation group. The ECGs of the patients' first examination, that is, the electrocardiograms of sinus rhythm, were collected to construct an ECG database. 2. Prospective study: The electrocardiograms collected in the Cardiac Function Room of our hospital from April 2024 to June 2024 were collected. Based on the improved AlexNet model, AI electrocardiograms were formed. According to the output values of the AI electrocardiograms, the subjects were divided into the low atrial fibrillation (AF) risk group and the high AF risk group, with 100 people included in each group.
Exclusion criteria
Exclusion criteria: 1. If the electrocardiogram examination shows atrial fibrillation or atrial flutter for the first time or if the quality of the graphic acquisition is not good, the subjects will not be included in the study. 2. Prospective study: Patients will not be included in the research subjects if they are diagnosed with atrial fibrillation/atrial flutter during the electrocardiogram (ECG) examination; if the quality of the graphic acquisition is poor; if they are unable to participate in the clinical study; or if they refuse to sign the informed consent form.
