Detection of Obstructive Sleep Apnea (OSA) is important as it is closely related to the cause of sudden death, due to heart failure during sleep. In this article, the method for OSA detection utilizes electrocardiographic parameters: QRS interval, QT interval and RT interval. The parameters are used for inputs of discriminant analysis. To find the … Read more
The aim of this study is to propose a method to measure QT interval of electrocardiogram (ECG). Firstly, in this proposed QT interval measurement, the P-wave and QRS complex of ECG signal is removed to detect the T end. Then, the ECG signal is passed through differentiated process. T end is defined as point where … Read more
In this study, Android smartphone is used for heart rate monitoring and displaying electrocardiogram (ECG) graph. Heart rate determination is based on QRS peak detection. Two methods are studied to detect the QRS complex peak; they are Peak Threshold and Peak Filter. The acquisition of ECG data is utilized by AD8232 module from Analog Devices, … Read more
