Heart Rhythm, 2017
Frequent premature ventricular complexes (PVCs) have been associated with increased mortality. However, the optimal approach to the risk stratification of these patients is unclear.The purpose of this study was to prospectively assess the use of cardiac magnetic resonance imaging (MRI) and programmed ventricular stimulation to identify patients with ...

Interruption of cardiac resynchronization therapy by atrial premature complexes
Journal of Electrocardiology, 2018Biotronik 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 ...

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 and Nonsustained Ventricular Tachycardia in Cardiac Sarcoidosis
JACC: Clinical ElectrophysiologyThe 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 ...

Heart Rhythm
Ablation of premature ventricular complexes (PVCs) originating from the parahisian area is challenging. Late gadolinium-enhanced cardiac magnetic resonance (LGE-CMR) scar may influence procedural outcomes; the impact of cardiac scar on parahisian PVCs has not been described.The objective of this study was to examine the incidence and significance of ...

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.

Relation between ventricular premature complexes and sudden cardiac death in apparently healthy men
The American Journal of Cardiology, 1987The 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 ...

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 ...

Atrial fibrillation (AF) is associated with increased morbidity and mortality. We sought to determine whether atrial premature complexes (APCs) detected during a standard exercise stress test (EST) in patients undergoing cardiac rehabilitation (CR) are associated with an increased risk of AF.
