1. An electrocardiograph comprising:
an electrocardiographic measurement unit including a pair of electrodes and a first circuit, the first circuit being configured to generate a potential difference signal indicating a potential difference between the electrodes and measure electrocardiographic information of a user based on the potential difference signal;
a physiological indicator measurement unit including a sensor and a second circuit configured to measure a physiological indicator that is an indicator associated with a biological information of the user based on an output of the sensor, the physiological indicator being different from the electrocardiographic information; and
a processor configured to:
determine whether or not the user is in a relaxed state, on the basis of a measurement result of the physiological indicator;
in response to a determination that the user is in the relaxed state, control the electrocardiographic measurement unit to start measuring the electrocardiographic information and control the physiological indicator measurement unit to stop measuring the physiological indicator;
determine whether or not the user is in the relaxed state, on the basis of a measurement result of the electrocardiographic information during a period in which the electrocardiographic measurement unit measures the electrocardiographic information; and
in response to a determination that the user is not in the relaxed state, control the electrocardiographic measurement unit to stop measuring the electrocardiographic information and control the physiological indicator measurement unit to perform measuring of the physiological indicator.
