Performance comparisons between two artificial intelligence based premature ventricular complex detection models using insertable cardiac monitor

European Heart Journal, 2023
Abstract Background Premature ventricular complex (PVC) detection using computationally simple techniques has been recently introduced in insertable cardiac monitors (ICMs). An ICM device capable of monitoring PVC burden over a longer period can be a useful tool for evaluating temporal dynamics of PVC

Premature ventricular complexes are not independently associated with concurrent paroxysmal atrial fibrillation on mobile cardiac telemetry

European Heart Journal, 2022
Abstract Background Premature ventricular complexes (PVCs) on 24hECG predict incident atrial fibrillation in long-term prospective studies, but whether PVCs detected on ambulatory monitoring indicate a risk of concurrent paroxysmal atrial fibrillation is unknown.

Cardiac magnetic resonance of healthy children and young adults with frequent premature ventricular complexes

Journal of Cardiovascular Medicine, 2007
To assess whether magnetic resonance imaging could detect any cardiac morphological or functional myocardial alterations in healthy children and young adults with ventricular arrhythmias.Twenty-three subjects (14 male, mean age 15.6 +/- 6.5 years) with frequent (> or =30/h) premature ventricular complexes (PVCs) on Holter monitoring and normal ...

Night-Time Premature Ventricular Complex Positively Correlates With Cardiac Sympathetic Activity in Patients Undergoing Radiofrequency Catheter Ablation

Heart, Lung and Circulation, 2020
Patients with premature ventricular complexes (PVCs) usually experience accompanying alterations of the autonomic nerve system. The timing of PVC occurrence is associated with different circadian rhythms, which may be related to the autonomic nerve imbalance.

Termination of desynchronization rhythm and restoration of cardiac resynchronization by left‐sided ventricular premature complexes

Pacing and Clinical Electrophysiology, 2019
AbstractCardiac resynchronization devices that sense left ventricular (LV) activity and can detect interruptions of resynchronization therapy are able to record all forms of desynchronization rhythms, which are triggered by misalignment of LV timing cycles.

Meta-Analysis of Ventricular Premature Complexes and Their Relation to Cardiac Mortality in General Populations

The American Journal of Cardiology, 2013
Although previous studies have shown that frequent ventricular premature complexes (VPCs) in patients with established heart disease are associated with increased risk of cardiac mortality, the significance of VPCs in general populations is unclear. The aim of this study was to assess the association between VPCs and risk of sudden cardiac death or ...

Idiopathic premature ventricular complexes originating from the distal great cardiac vein: Clinical, cardiac and electrophysiological characteristics and catheter ablation outcome

Life Sciences, 2018
Although catheter ablation for idiopathic ventricular arrhythmia (VA) has been generally well-established, VA originating from the great cardiac vein (GCV) may be clinically challenging due to its epicardial origin, proximity to coronary arteries and limited accessibility.

Premature Ventricular Complexes and Nonsustained Ventricular Tachycardia in Cardiac Sarcoidosis

JACC: Clinical Electrophysiology
The prevalence and prognostic significance of frequent premature ventricular complexes (PVCs) and nonsustained ventricular tachycardia (NSVT) in cardiac sarcoidosis (CS), especially in patients with normal or mildly decreased left ventricular function, have not been studied.This study sought to investigate the prognostic value of PVCs and NSVT in ...

Clinical predictors and implications of cardiac inflammation detected on positron emission tomography (PET) in patients referred for premature ventricular complex (PVC) ablation

Journal of Interventional Cardiac Electrophysiology, 2022
Positron emission tomography computed tomography (PET-CT) is not routinely used for premature ventricular complexes (PVCs). Whether specific clinical factors are associated with abnormal PET-CT results is not clear.The treatment courses and baseline characteristics of consecutive patients in a single center between 2012 and 2021, age > 18 years old ...
