An electrocardiogram analysis apparatus includes: an electrocardiogram signal inputting section to which electrocardiogram signals of measurement electrodes attached to a subject are input； a mistaken attachment determining section which, by using the input electrocardiogram signals, determines whether the measurement electrodes are mistakenly attached or not； an outputting section which, if it is determined that the measurement electrodes are mistakenly attached, notifies of mistaken attachment of the measurement electrodes； and an electrocardiogram data storing section which, in a case where there is an input indicative of confirmation of the notification, stores information indicating that the measurement electrodes have been checked, together with the input electrocardiogram signals, and, in a case where there is not an input indicative of confirmation of the notification, stores information indicating that the measurement electrodes have not been checked, together with the input electrocardiogram signals.
