Detection of abnormal and induction of normal heart rate variability

摘要

A microprocessor (300) with a date and time clock gathers time interval data (80, 86). The duration of the time intervals in an electrocardiogram, or pulses are recorded. Stress data accumulated for the user are down loaded to a PC (301). The battery power pack (303) supplies electricity to operate the components (80-318). The user's stress status is displayed on a liquid crystal diode (302), and the voice microprocessor (318) broadcasts from a microspeaker CPR instructions. If the battery (303) has less than a 20% charge, a buzzer (304) notifies the user.
