Design of a web laboratory interface for ECG signal analysis using MATLAB builder NE
Open Computer Science, 2022 An electrocardiogram (ECG) is a noninvasive test, determining any defect in the heart rate or rhythm or changes in the shape of the QRS complex is very significant to detect cardiac arrhythmia.

Postextrasystolic Changes in the Complexity of the QRS Complex and T Wave [PDF]
Annals of Noninvasive Electrocardiology, 2008 We tested the hypothesis that ventricular repolarization of the first sinus beat following a ventricular premature beat (VPB) can be modulated in the absence of clearly discernible T‐wave changes. We applied principal component analysis (PCA) to assess QRS and T‐wave complexity of sinus beats preceding and following VPBs in multiple 10‐second resting ...

Is there a utility for QRS dispersion in clinical practice? [PDF]
, 2017 Prognostic markers derived from standard ECG have always been seductive. Increased dispersion of durations of the P wave, of the QRS complex, or of the QT interval has been associated with the risk of atrial fibrillation, ventricular arrhythmias, sudden ...

Comparison of three ECG machines for electrocardiography in green iguanas (Iguana iguana)
Veterinární Medicína, 2021 The aim of the study was to compare the heart rate, QRS interval, and R wave amplitude across three electrocardiogram models, and assess the ability of each of them to provide electrocardiograms (ECG) for clinical interpretation.
