A QRS Detection and R Point Recognition Method for Wearable Single-Lead ECG Devices

In the new-generation wearable Electrocardiogram (ECG) system, signal processing with low power consumption is required to transmit data when detecting dangerous rhythms and to record signals when detecting abnormal rhythms. The QRS complex is a combination of three of the graphic deflection seen on a typical ECG. This study proposes a real-time QRS detection and R point recognition method with...

Embedded QRS Detection for Noisy ECG Sensor Data Using a Matched Filter and Directed Graph Search

In a lot of medical as well as sports applications, the precise recognition of heart beat (HB) events in electrocardiogram (ECG) sensor signals is mandatory to facilitate subsequent diagnosis and analysis of the data. However, especially in the presence of motion, e.g. in sports or sleep monitoring, the signal-to-noise ratio of such signals can become very low. This paper discusses the accurate...

An Adaptive and Time-Efficient ECG R-Peak Detection Algorithm

R-peak detection is crucial in electrocardiogram (ECG) signal analysis. This study proposed an adaptive and time-efficient R-peak detection algorithm for ECG processing. First, wavelet multiresolution analysis was applied to enhance the ECG signal representation. Then, ECG was mirrored to convert large negative R-peaks to positive ones. After that, local maximums were calculated by the first-or...

Implementation of a portable device for real-time ECG signal analysis

BACKGROUND Cardiac disease is one of the main causes of catastrophic mortality. Therefore, detecting the symptoms of cardiac disease as early as possible is important for increasing the patient's survival. In this study, a compact and effective architecture for detecting atrial fibrillation (AFib) and myocardial ischemia is proposed. We developed a portable device using this architecture, which...

Steep slope method for real time QRS detection

A method for real time QRS detection by assessment of the signal steep slopes is proposed. It is based on comparison of the absolute value abs(D) of the differentiated electrocardiogram (ECG) to a varying threshold value. The method is independent of threshold and weighting constant. It is adaptive and self-synchronized to the steep slope of the QRS, regardless of the amplitude and the sampling...
