Apparatus for measuring electrocardiogram and method of recording ecg signals merged with user input

A method of measuring an electrocardiogram and storing an electrocardiogram digital signal merged with a user input, the method comprising:

• outputting an electrocardiogram analog signal by detecting an electrical signal from the heart of an object, the outputting being performed by an apparatus for measuring an electrocardiogram;
• receiving the electrocardiogram analog signal and converting the electrocardiogram analog signal into an electrocardiogram digital signal, the receiving and converting being performed by the apparatus;
• receiving at least one type of user input from at least one among a voice input, a button input, a touch input, and a motion input, the receiving being performed by the apparatus;
• receiving the user input, merging the electrocardiogram digital signal with the user input, and storing the electrocardiogram digital signal in an internal memory, the receiving, merging, and storing being performed by the apparatus;
• and
• communicating with an external terminal to transmit the electrocardiogram digital signal to the external terminal, the communicating being performed by the apparatus.
