RETRACTED ARTICLE: Anti-fibrotic mechanism of SPP1 knockdown in atrial fibrosis associates with inhibited mitochondrial DNA damage and TGF-β/SREBP2/PCSK9 signaling

Cell Death Discovery, 2022
Atrial fibrosis occurs frequently with structural heart disease and is considered as a major cause of arrhythmia. Microarray-based profiling predicted the differential expression of SPP1 in atrial fibrosis.

Modern mapping and ablation of idiopathic outflow tract ventricular arrhythmias

Reviews in Cardiovascular Medicine, 2022
Outflow tract (OT) premature ventricular complexes (PVCs) are being recognized as a common and often troubling, clinical electrocardiographic finding. The OT areas consist of the Right Ventricular Outflow Tract (RVOT), the Left Ventricular Outflow Tract (

Constrained transformer network for ECG signal processing and arrhythmia classification

BMC Medical Informatics and Decision Making, 2021
Background Heart disease diagnosis is a challenging task and it is important to explore useful information from the massive amount of electrocardiogram (ECG) records of patients. The high-precision diagnostic identification of ECG can save clinicians and

Left Atrial Spontaneous Echo Contrast and Ischemic Stroke in Patients Undergoing Percutaneous Left Atrial Appendage Closure

Frontiers in Cardiovascular Medicine, 2021
Objectives: Spontaneous echo contrast (SEC) in the left atrium (LA) is frequently observed in atrial fibrillation (AF) patients and may lead to thromboembolic events.

A Hybrid Deep Learning Approach for ECG-Based Arrhythmia Classification

Bioengineering, 2022
Arrhythmias are defined as irregularities in the heartbeat rhythm, which may infrequently occur in a human’s life. These arrhythmias may cause potentially fatal complications, which may lead to an immediate risk of life.

Ablation with zero‐fluoroscopy of premature ventricular complexes from aortic sinus cusps: A single‐center experience

Journal of Arrhythmia, 2021
Background Catheter ablation of premature ventricular complexes from aortic sinus cusps (ASC‐PVC) is a complex procedure that conventionally requires coronary catheterization (CC) to localize coronary artery ostium (CAO).

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

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.

Early-Onset Atrial Fibrillation and the Prevalence of Rare Variants in Cardiomyopathy and Arrhythmia Genes

JAMA cardiology, 2021
Key Points Question In patients diagnosed with atrial fibrillation before 66 years of age, what is the prevalence of disease-associated variants in susceptibility genes for inherited cardiomyopathy and arrhythmia syndromes? Findings In this cohort study,
