Abstract: Provided is a biofeedback device using an electrocardiogram, and the biofeedback device using an electrocardiogram may include: a signal acquisition unit acquiring an electrocardiogram signal of a user from an electrocardiograph; an analysis unit analyzing the acquired electrocardiogram signal and providing a state diagnosis result of the user as an analysis result; and a control unit controlling at least one stimulation unit among a plurality of stimulation units for state control of the user based on the state diagnosis result, and a stimulation corresponding to the at least one stimulation unit may be provided to the user by the control of the control unit.

Abstract: Provided is an electrocardiogram lead guide system. The electrocardiogram lead guide system may include: an electrocardiograph attached to a part of a body of a patient and acquiring posture information and electrocardiogram signals using a plurality of sensors; and a user terminal providing guide information for guiding the attachment direction of the electrocardiograph based on the posture information.

Abstract: The present invention relates to a system to transmit vital signals from a moving human body in the presence of dynamic external disturbance and to compensate for artifacts thereof. More specifically, it relates to a system to compensate for artifacts caused by external noise during measurement of vital signals, and to display index of vibration on the monitoring system through interpretation of the vibration signals which affect the physiological state of the body and the measurement of vital signals, due to external disturbance factors, when noise from external disturbances such as vibration of a moving ambulance vehicle, vibration of a remote transmitting diagnostic device attached to the patient, or movement of the patient, is mixed into the transmitted signals. The present invention provides a start code, a data code, a degree of vibration and movement level, a three axis acceleration value and signals of three axis acceleration and measured vital signals.
