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.

A biological information trend display device and method which allow the trend and an abnormal value of biological information to be checked with ease are provided. When a curve () showing the ST level in lead Vexceeds the upper limit of a normal range, the part of the curve above the upper limit is displayed in an abnormal color 'b' (red, for example). To indicate that the ST level derived from the lead Vhas exceeded the upper limit, a lead icon () in an upper part of the display screen is displayed in the abnormal color 'b.'

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 cardiogram waveform correcting and displaying device is disclosed that is capable of facilitating visibility of cardiogram waveforms. A first filtering system-through nth filtering system-are low-cut filters, each having a first cutoff frequency fcthrough an nth cutoff frequency fcn, respectively. Recognition module recognizes feature values of waveforms related to variation of the waveforms in accordance with any outputs of the first filtering system-through the nth filtering system-. Judging moduleselects which of the first through the nth filter is used based on the recognized feature values with the recognition module. A filter which restricts base-line variation is used when the base-line variation is large, and a filter having less influence to waveforms is used when the base-line variation is small. Display controller displays on a display portion output of the selected filter.

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.

A vital sign display device and method which allows a vital sign to be checked easily is provided. A vital sign item name is displayed at the center of a circle radar (). The circle part of the circle radar () is colored in gray, for example, at the beginning of the measurement. An indication point moves clockwise in the circle radar () as the measurement time proceeds. Green is displayed while VPCs (ventricular premature contractions) do not occur, and red is displayed when VPCs occur.
