1. An electrocardiogram analyzer comprising:
an electrocardiogram measuring unit configured to measure an electrocardiogram based on an electrocardiographic signal of an electrode attached to an outside of a body of a subject;
a motion measuring unit configured to measure body motion based on body motion information of a sensor attached to the outside of the body of the subject;
an analyzer configured to analyze occurrence of serious arrhythmia based on the electrocardiogram measured by the electrocardiogram measuring unit and the body motion measured by the motion measuring unit;
an arrhythmia analyzer configured to analyze occurrence of arrhythmia based on the measured electrocardiogram;
a motion analyzer configured to analyze a type of the measured body motion; and
a validity analyzer configured to analyze validity of determining that the arrhythmia is serious arrhythmia based on the type of the body motion when the occurrence of the arrhythmia is analyzed.
