Heart beat analysis device and method

A heartbeat analysis method, comprising:

• (1) operating, according to a user's selection mode, in any one of
• a radio reception mode,
• a digital retrieval mode, or
• a heartbeat measurement-related information setting mode;
• (2) receiving and storing digital music files;
• (3 if operating in the heartbeat measurement-related information setting mode, inputting and storing heartbeat reference values;
• (4) if operating in the radio reception or digital retrieval mode, using an external unit to measure heartbeat data, including a heartbeat value, of a user during physical exercise;
• (5) if operating in the radio reception or digital retrieval mode, determining that the external unit transferred the heartbeat data;
• (6) comparing the heartbeat value with the reference values and outputting a signal if the heartbeat value is above an upper limit or below a lower limit of the reference values;
• (7) connecting to an external personal computer and transferring the heartbeat data to the personal computer for analysis, where the analysis comprises a determination of
• a change degree of the number of heartbeats by time,
• a change degree of the number of heartbeats by unit time period,
• a suitable exercise amount based on a change in the number of heartbeats,
• an exercise effect based on a change in the number of heartbeats,
• calories consumed during physical exercise, and
• a percentage of body fat decomposition;
• (8) outputting and storing the results of the analysis in the personal computer.
