Electrocardiogram analysis apparatus and electrocardiogram system

An electrocardiogram system which includes an electrocardiograph that acquires electrocardiogram data of a subject, and an external computer that stores the electrocardiogram data acquired by the electrocardiograph, and in which the electrocardiograph and the external computer are communicable with each other, wherein

• the electrocardiograph includes:
• an electrocardiogram signal inputting section to which electrocardiogram signals of a plurality of measurement electrodes that are attached to the subject are input;
• a mistaken attachment determining section which, by using the input electrocardiogram signals, is configured to determine whether the measurement electrodes are mistakenly attached or not;
• and
• a notifying section which, if it is determined that the measurement electrodes are mistakenly attached, is configured to notify of mistaken attachment of the measurement electrodes, and
• the external computer includes:
• an electrocardiogram data storing section which, in a case where there is an input indicative of confirmation of the notification, is configured to store 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, is configured to store information indicating that the measurement electrodes have not been checked, together with the input electrocardiogram signals;
• and
• an outputting section that is configured to output the information indicating that the measurement electrodes have been checked, or the information indicating that the measurement electrodes have not been checked, together with the electrocardiogram signals.
