Such QRS complex represents the depolarization state of the heart activity. To detect QRS complex, the proposed algorithm procedures use wavelet transforms. In fact, the proposed method is based on Wavelet transform decomposition of ECG signal using reverse Biorthogonal mother wavelet. The resulting ...
where sa(n) represents the average ECG signal shown in Fig. 2c, and sad(n) represents the average difference signal shown in Fig. 2d. The number of samples in sr(n) is Ni times more than that in sa(n). ECG signal segmentation A heartbeat is commonly composed of P-wave, QRS compl...
A readily available ECG parameter that has recently gained attention is the QRS‐T angle. It is the angle between the axis of the QRS complex and the axis of the T‐wave and represents a measure of cardiac depolariza...
In subject area: Biochemistry, Genetics and Molecular Biology This is defined as the period between the beginning of the QRS complex (depolarization of the ventricles) and the end of the T-wave (repolarization of the ventricles) on an electrocardiogram (ECG). ...

Fragmented QRS on twelve-lead electrocardiogram predicts arrhythmic events in patients with ischemic and nonischemic cardiomyopathy Myocardial scar is a substrate for reentrant ventricular arrhythmias and is associated with poor prognosis. Fragmented QRS (fQRS) on 12-lead ECG represents... MK Das,W Ma...

Objectives To investigate whether a prolonged electrocardiographic(ECG) QRS duration is an independent predictor of clinical severity and mortality in patients with idiopathic pulmonary arterial hypertension (IPAH). Background A prolonged QRS duration(120 ms) and left ventricular dyssynchrony have previously...
Electrocardiographic (ECG) signs of left ventricular hypertrophy (LVH) lack sensitivity. The aim was to identify LVH based on an abnormal spatial peaks QRS-T angle, evaluate its diagnostic performance compared to conventional ECG criteria for LVH, and it
in the normal heart theR waverepresents predominantly the uncanceled transmural excitation potentials of theleft ventricle. The terminal portion of the normal QRS complex represents posterobasal depolarization of the septum and both ventricles and can be represented by a superiorly oriented QRS deflection...
