Classification of Arrhythmia by Using Deep Learning with 2-D ECG Spectral Image Representation

Remote Sensing, 2020
The electrocardiogram (ECG) is one of the most extensively employed signals used in the diagnosis and prediction of cardiovascular diseases (CVDs). The ECG signals can capture the heart’s rhythmic irregularities, commonly known as arrhythmias.

Premature Atrial and Ventricular Contraction Detection Using Photoplethysmographic Data from a Smartwatch

Sensors, 2020
We developed an algorithm to detect premature atrial contraction (PAC) and premature ventricular contraction (PVC) using photoplethysmographic (PPG) data acquired from a smartwatch.

Left ventricular dyssynchrony as marker of early dysfunction in premature ventricular contraction-induced cardiomyopathy [PDF]

Frontiers in Cardiovascular Medicine, 2022
BackgroundStrain imaging has been suggested as a tool to detect early left ventricular (LV) dysfunction due to frequent premature ventricular contractions (PVCs) in patients with preserved LV ejection fraction (EF).

An Automatic Premature Ventricular Contraction Recognition System Based on Imbalanced Dataset and Pre-Trained Residual Network Using Transfer Learning on ECG Signal

Diagnostics, 2022
The development of automatic monitoring and diagnosis systems for cardiac patients over the internet has been facilitated by recent advancements in wearable sensor devices from electrocardiographs (ECGs), which need the use of patient-specific approaches.

Relationship of Arrhythmogenic Substrate and Frequent Ventricular Extrasystoles in Patients with Nonischemic Cardiomyopathy

Journal of Cardiac Arrhythmias, 2020
Cardiomyopathies (CMP) are related with scarring tissue due to fibrotic and disarrangement of myocardial fibers that promote an slowed conduction and substrate for sustained reentrant ventricular arrhythmias.

Using Three-Dimensional Lorenz Scatter Plots to Detect Patients with Atrioventricular Node Double Path Caused by Interpolated Ventricular Premature Systoles: A Case Study

Cardiovascular Innovations and Applications, 2021
A series of related electrophysiology phenomena can be caused by the occurrence of interpolated ventricular premature contraction. In our recent three-dimensional Lorenz R-R scatter plot research, we found that atrioventricular ...

Limitations of Unipolar Signals in Guiding Successful Outflow Tract Premature Ventricular Contraction Ablation.

JACC Clinical Electrophysiology, 2022
OBJECTIVES The authors sought to compare bipolar electrograms (BiEGMs) vs unipolar electrograms (UniEGMs) in guiding successful ablation of right ventricular outflow tract (RVOT) vs intramural outflow tract (OT) premature ventricular contractions (PVCs).

Association of Premature Ventricular Contraction Burden on Serial Holter Monitoring With Arrhythmic Risk in Patients With Arrhythmogenic Right Ventricular Cardiomyopathy.

JAMA cardiology, 2022
Importance A high burden of premature ventricular contractions (PVCs) at disease diagnosis has been associated with an overall higher risk of ventricular arrhythmias in arrhythmogenic right ventricular cardiomyopathy (ARVC).
