A method for presenting an ST event in an electrocardiogram (ECG) comprises: drawing an amplitude trend graph of an ST segment in the ECG； detecting an ST event in the amplitude trend graph of the ST segment； and marking the detected ST event in the amplitude trend graph of the ST segment. In the present invention, the ST event is automatically detected and marked in the amplitude trend graph of the ST segment, so that the ST events are presented more intuitively, and the user can intuitively and quickly locate the ST event in the amplitude trend graph of the ST segment and quickly know a raised or depressed situation of the ST event； the time of subsequent analysis and summary can be effectively reduced, and a blood supply state of the heart of the subject can be timely and quickly known.
