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 ...

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 ...

Relation between ventricular premature complexes and sudden cardiac death in apparently healthy men

The American Journal of Cardiology, 1987
The association between ventricular premature complexes (VPCs) detected on a rest 2-minute lead I electrocardiographic rhythm strip and sudden cardiac death (SCD), occurring within 1 hour of onset of symptoms, was evaluated in a prospective study of 15,637 apparently healthy white men, aged 35 to 57 years, at the first screening examination (1973 to ...

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.

Left ventricular inhibition during cardiac resynchronization caused by sensed left‐sided ventricular premature complexes

Pacing and Clinical Electrophysiology, 2020
AbstractA recently published case documented left ventricular (LV) inhibition of a Boston Scientific device by a premature complex (VPC) that was undetected by the right ventricular channel. We have observed a similar response in two patients with a BIOTRONIK cardiac resynchronization device also designed with LV sensing. A spurious response simulating

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.
