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.

Premature Ventricular Contraction-Induced Cardiomyopathy [PDF]

Circulation: Arrhythmia and Electrophysiology, 2012
Premature ventricular contractions (PVCs) are early depolarizations of the myocardium originating in the ventricle. They are often seen in association with structural heart disease and represent increased risk of sudden death,1 yet they are ubiquitous, even in the absence of identifiable heart disease.1,2 They may cause troubling and sometimes ...

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 ...

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.

Effect of Echocardiographic Epicardial Adipose Tissue Thickness on Success Rates of Premature Ventricular Contraction Ablation

Balkan Medical Journal, 2019
Background: Idiopathic premature ventricular contractions are frequently detected ventricular arrhythmias, and radiofrequency ablation is an effectively treatment for improving symptoms and eliminating premature ventricular contractions.

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.
