Heart Rate Variability of Photoplethysmography for Hypertension Detection Using Support Vector Machine

by

Abstract: Early detection of hypertension is essential as it is a common chronic age-related disease often associated with debilitating cardiovascular complications. The aim of this article is to find the best accuracy performance in detecting hypertension. This article introduced a method for hypertension detection without a cuff using parameters of photoplethysmography (PPG) and support vector … Read more

Obstructive Sleep Apnea Detection using Frequency Analysis of Electrocardiographic RR Interval and Machine Learning Algorithms

by

Background: Obstructive Sleep Apnea (OSA) is a respiratory disorder due to obstructive upper airway (mainly in the oropharynx) periodically during sleep. The common examination used to diagnose sleep disorders is Polysomnography (PSG). Diagnose with PSG feels uncomfortable for the patient because the patient’s body is fitted with many sensors. Objective: This study aims to propose … Read more

A new automatic qt-interval measurement method for wireless ecg monitoring system using smartphone

by

Abstract: QT-interval prolongation is an important parameter for heart arrhythmia diagnosis. It is the time interval from QRS-onset to the T-end of electrocardiogram (ECG). Manual measurement of QT-interval, especially for 12-leads ECG, is time-consuming. Hence, an automatic QT-interval measurement is necessary. A new method for automatic QT-interval measurement is presented in this paper, which mainly … Read more
