The heartbeat class detection of the electrocardiogram is important in cardiac disease diagnosis. For detecting morphological QRS complex, conventional detection algorithm have been designed to detect P, QRS, T wave. However, the detection of the P and T wave is difficult because their amplitudes are relatively low, and occasionally they are included in(More)
We have evaluated the sequence diversity of the protease human immunodeficiency virus type 1 in vivo. Our analysis of 246 protease coding domain sequences obtained from 12 subjects indicates that amino acid substitutions predicted to give rise to protease inhibitor resistance may be present in patients who have not received protease inhibitors. In addition,(More)
The purpose of this research was to effectively estimate the physical activity energy expenditure considering acceleration and ECG using the developed holter that is contained a tri-axial accelerometer. For this research, we developed the specific device that can measure three channels’ ECG and three axes’ accelerations simultaneously. The every experiment(More)
In the NIBP (Non-Invasive Blood Pressure) measurement, we need well trained observer and there are differences in reading values between observers. We suggest new automated auscultation algorithms to select the proper epoch of K-sound for each heart beat. The sound for each epoch is converted into frequency domain and total power was calculated. We decided(More)
Oscillometric method is the method for the blood pressure measurement using mean arterial pressure (MAP). In the conventional method, the cuff pressure at the largest pulse is determined as MAP. However, it is difficult to find the largest oscillometric pulse from patients who have the cardiovascular disease or the elder subjects. Therefore, we studied a(More)
In non-invasive blood pressure (NIBP) measurement, most of the automatic devices use oscillometric method. There are two types of deflation in oscillometric method. One is the linear deflation and the other is the stepwise deflation method. In this study, we suggest the modified step deflation to reduce the measurement time while keeping the advantage of(More)
