The ECG recorded by Einthoven withan even more refined Lippmann capillaryelectrometershowed 4 deflections. Einthoven labeled these waves ABCD. He eliminated the letter P, shifted the letter A to indicate electrical activity of the atria, and used B...

Narrow and broad/Wide QRS complex morphology Low/high voltage QRS, differential diagnosis, causes and spot diagnosis on LITFL ECG library
In this work, we have developed an electrocardiogram (ECG) feature extraction system based on the multi-resolution wavelet transform. It mainly includes two stages. In the first stage, algorithm is quoted by using discrete wavelet transform for de-noise the signal. In second step multiresolution ...

Study populations were divided into fQRS group and non-fQRS group according to the existence of fQRS on electro- cardiography ( ECG) . Before CRT implantation as well as 6 months after implantation,New York Heart Association ( NYHA) class, ECG and echocardiography were evaluated. Response to ...
on a standard 12-lead ECG, from the onset of the QRS complex to its terminal components. Indeed, measurement of the QRS duration in a single lead may frequently result in an inaccurate evaluation and, therefore, it should be avoided. The approach to an ECG showing wide QRS complexes ...
This file contains functions for detecting QRS complexes in an ECG. The QRS detector requires filter functions in qrsfilt.cpp and parameter definitions in qrsdet.h. QRSDet is the only function that needs to be visable outside of these files. ...
QRS wave group detection based on B-Spline wavelet and adaptive threshold An effective algorithm for detecting QRS wave group was presented. The ECG signal is de-composed with the equivalent filter of a biorthogonal spline wavele... Q Chen,J Liu,G Li - International Conference on Computer 被...
