Abstract: A method of recording information for use in generating an electrocardiogram indicative of a health status of a user's heart, the method being operable using a device (1) which includes: a housing (2); a processor (3) disposed in the housing (3); first and a second input terminal (4a,4b) disposed on the housing (2), wherein the first and second input terminals (4a,4b) are operatively connected to the processor (3); and a display (5) operatively connected to the processor (3); wherein the method includes the steps of: (i) contacting a right and left thumb (8a,8b) of the user with the first and second input terminals (4a,4b) respectively; and (ii) the processor (3) detecting an ECG signal formed between the first and second input terminals (4a,4b), wherein the ECG signal is indicative of the health status of the user's heart.
