One embodiment provides a garment for measuring biological information, a measurement system, a measurement device and a method of controlling thereof capable of measuring biological information with accuracy regardless of variations of each examinee. When an examinee wears a shirt, four limb electrodes are arranged at positions so that the electrodes cover the body surface other than around the clavicle. At that time, the four limb electrodes are assigned to positions so that they cover about the pelvis. Also, during the use of the shirt, chest electrodes cover from the body surface (around lower part of left side of the body) of a presternal region around the left thorax in a perpendicular direction of the body axis (a direction perpendicular to the length of the shirt) and the electrodes are assigned so as to cover from the body surface around the fourth rib to that around the sixth rib.

A peak-relevant value device acquires a peak-relevant value (for example, the peak value of an R wave (R peak value)) every cycle from an electrocardiogram acquired. The frequencies of the peak-relevant value acquired as time-series data and the magnitudes for the respective frequencies are analyzed. A peak-relevant value LF calculating device calculates an LF component (peak-relevant value LF component) from the frequency component of the peak-relevant value. An interval acquiring device acquires the interval between characteristic points of the electrocardiographic complex from the electrocardiogram acquired and the frequencies of the feature point interval acquired as time-series data to acquire the magnitudes of the respective frequency component are analyzed. An interval HF calculating device calculates the HF component from the frequency components of the feature point interval acquired and pain is judged on the basis of the variations of the peak-relevant value LF components and the interval HF components.

An electrocardiogram (ECG) chart device and method capable of easily assisting with the diagnosis of heart disease. Hexagonal radar charts displayed on a screen act as indicators of feature values corresponding to data obtained from each of 12 electrode leads and correlated with the related portions of the heart. For example, a (V1, V2) lead is an indicator of a right ventricle. Each of the radar charts is schematically arranged to correspond with the related portion of the heart. Each vertex of the hexagonal radar charts acts as an indicator of the recognized value. More specifically, each vertex of the radar chart is based on a value obtained by extracting a waveform critical point, a waveform start point, a waveform end point, or the like, of constituent elements of the ECG waveform as the P wave, the Q wave, the R wave, the S wave, the ST segment, the T wave, or the like. Therefore, a user of the ECG radar chart device can intuitively and easily carry out interpretation of ECG data.

A graph display processing device and method that facilitates easy viewing of data with periodicity. With each recognition of a cardiac cycle, a CPU of an electrocardiogram display device () finds a point between an R-wave and an S-wave in the cardiac cycle and at two-thirds from the lowest point, as a central point of the cardiocyclic waveform. The CPU determines whether or not the central point is displayed in a central region defined as one-third of the center of a display. When the central point is not in the central region, the CPU performs a scroll process on the electrocardiogram.
