==Original Abstract Submitted==

An electrocardiac signal analysis device measures an electrocardiac signal of a subject in a daily environment such as an office. The electrocardiac signal is analyzed by a plurality of methods, contributing to accurate evaluation of a health condition of the subject. A measurement unit includes a pair of detection electrodes of a capacitive coupling type that detect a heart rate of a subject in a non-contact state and output the heart rate as primary signals. A pair of active guard circuits reduce noise in the primary signals and output secondary signals. A potential difference of the secondary signals is amplified and output as an electrocardiac signal. A feedback electrode is configured to remove an influence of an in-phase signal of the secondary signals. An analysis unit linearly analyzes the electrocardiac signal to calculate an autonomic nerve index, and nonlinearly analyzes the electrocardiac signal to calculate a Lyapunov exponent.
