The Importance of ECG Offset Correction for Premature Ventricular Contraction Origin Localization from Clinical Data

Measurement Science Review, 2022
In this study, the inverse solution with a single dipole was computed to localize the premature ventricular contraction (PVC) origin from long term multiple leads ECG measurements on fourteen patients.

Premature ventricular contraction is associated with increased risk of atrial fibrillation: a nationwide population-based study

Scientific Reports, 2021
Premature ventricular contraction (PVC) and atrial fibrillation (AF) are common arrhythmias affecting 1–2% of the general population. During PVC, retrograde ventriculo-atrial activation can occur and act like an atrial ectopy.

Automated Classification Model With OTSU and CNN Method for Premature Ventricular Contraction Detection

IEEE Access, 2021
Premature ventricular contraction (PVC) is one of the most common arrhythmias which can cause palpitation, cardiac arrest, and other symptoms affecting the work and rest activities of a patient.

Activation recovery interval imaging of premature ventricular contraction. [PDF]

PLoS ONE, 2018
Dispersion of ventricular repolarization due to abnormal activation contributes to the susceptibility to cardiac arrhythmias. However, the global pattern of repolarization is difficult to assess clinically.

Transfer learning in ECG classification from human to horse using a novel parallel neural network architecture [PDF]

, 2020
Automatic or semi-automatic analysis of the equine electrocardiogram (eECG) is currently not possible because human or small animal ECG analysis software is unreliable due to a different ECG morphology in horses resulting from a different cardiac ...

An electrocardiographic anxiety- induced quadrigeminy and re-assurance

Egyptian Journal of Critical Care Medicine, 2018
Quadrigeminy means a cardiac arrhythmia in which every fourth beat is a premature ventricular contraction (extrasystole) or three sinus beats between extrasystoles.

Radiofrequency ablation of ventricular premature contraction originating from a native coronary cusp after transcatheter aortic valve replacement

Journal of Arrhythmia, 2017
We describe a case of radiofrequency ablation of ventricular premature contraction (VPC) originating from the left ventricular outflow tract after transcatheter aortic valve replacement. The VPC origin was the native aortic valve annulus between the left
