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 ...

Automatic QRS complex detection using two-level convolutional neural network
BioMedical Engineering OnLine, 2018 Background The QRS complex is the most noticeable feature in the electrocardiogram (ECG) signal, therefore, its detection is critical for ECG signal analysis.

QRS Complex Detection and Analysis of Cardiovascular Abnormalities: A Review [PDF]
International Journal Bioautomation, 2014 The ability to evaluate various Electrocardiogram (ECG) waveforms is an important skill for many health care professionals including nurses, doctors, and medical assistants. The QRS complex is a vital wave in any ECG beat.

Dynamic ECG Signal Quality Evaluation Based on the Generalized bSQI Index
IEEE Access, 2018 With the fast development of wearable electrocardiogram (ECG) monitoring, real-time and dynamic signal quality assessment (SQA) become an imperious demand. Thus, many signal quality indices (SQIs) have been developed in the past several years.

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.
