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 ...

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 ...

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.

Cardiac Magnetic Resonance in the Evaluation of Patients With Frequent Premature Ventricular Complexes

JACC: Clinical Electrophysiology, 2022
The role of cardiac magnetic resonance (CMR) in the evaluation and management of patients with frequent premature ventricular complexes (PVCs) of unknown etiology remains unclear.This study evaluated the prevalence and prognostic significance of myocardial abnormalities detected with CMR among patients with frequent PVCs and no known structural heart ...

Analytics of long-term premature ventricular complexes using an insertable cardiac monitor

European Heart Journal, 2023
Abstract Background Premature ventricular complexes (PVC) are associated with the development of cardiomyopathy, heart failure and pro-arrhythmia. PVC detection using insertable cardiac monitor (ICM) signal processing has recently been introduced.

Interruption of cardiac resynchronization therapy by atrial premature complexes

Journal of Electrocardiology, 2018
Biotronik devices used for cardiac resynchronization therapy (CRT) combined with defibrillation function (CRT-D) are capable of left ventricular (LV) sensing. Under certain circumstances, LV sensing may cause loss of CRT. The third generation of the Biotronik i-family CRT-Ds enables the recording of event-triggered tracings of the electrogram ...

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 ...

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.
