Objective: To see whether sudden unexpected death in chronic heart failure is preceded by intraindividual worsening in inflammation and in ECG criteria. De... A,M,A,... - 《Heart Official Journal of the British Cardiac Society》 被引量: 56发表: 2004年 QRS amplitude and volume changes during...
NN-Based R-peak Detection in QRS Complex of ECG Signal eural Network (NN) is designed to detect QRS complex from ECG signal. QRS complex detection is essential so that RR-interval can be measured for disease cl... MA Hasan,MI Ibrahimy,MBI Reaz - Springer Berlin Heidelberg 被引量: 14发...
The electrocardiogram (ECG) is a representation of electrical activity on a graph that occurs within the myocardium. The horizontal axis measures time in seconds on an ECG strip. Several important intervals that are determined on ...

本研究的目的是探讨QRS-T角(一种量化去极化-复极异质性的心电图(ECG)标志物)在疑似急性失代偿性心力衰竭(ADHF)患者中的诊断和预后价值。 Methods and results We prospectively enrolled unselected patients presenting to the emergency ...
ECG P QRS T onset and peak detection method A method and apparatus for detecting P or T waves in an electrocardiogram signal in intervals before and after each (previously) detected QRS wave. Within each interval, a candidate pair of samples are selected. If the candidate pair ar... NM Bu...

In this paper, we propose PVC classification based on QRS pattern using QS interval and R wave amplitude. For this purpose, we detected R wave, RR interval, QRS pattern from noise-free ECG signal through the preprocessing method. Also, we classified PVC in realtime through QS interval and ...
A QRS detection method based on the combined wavelet entropy (CWS) is proposed for two-channel ECG signals. The raw ECG signals from two channels are firstly transformed by the continuous wavelet transform within a selected frequency interval, which can effectively suppress the interference and only...
