Premature ventricular contraction-induced cardiomyopathy

Current Opinion in Cardiology, 2016
There has been a resurgent interest in frequent premature ventricular contractions (PVCs) led by the novel concept that they may be a potential cause of, or at least contribute to, cardiomyopathy. This review evaluates recent advances in our understanding of PVC-induced cardiomyopathy.Recent studies have focused on identifying the predictors of PVC ...

Twelve‐lead electrocardiographic localization of idiopathic premature ventricular contraction origins

Cardiovascular Electrophysiology, 2019
The major sites of origins of idiopathic ventricular arrhythmias have been elucidated. Idiopathic ventricular arrhythmias most often present as premature ventricular contractions (PVCs) with a focal mechanism, and commonly occur without structural heart ...

Determining the Optimal Duration for Premature Ventricular Contraction Monitoring.

Heart Rhythm, 2020
BACKGROUND Premature ventricular contractions (VPC) have hour-to-hour and day-to-day variation. High VPC burden correlates with cardiomyopathy. OBJECTIVE To determine the optimal duration for ambulatory ECG monitoring for accurate assessment of VPC ...

Geometrical features for premature ventricular contraction recognition with analytic hierarchy process based machine learning algorithms selection

Comput. Methods Programs Biomed., 2019
BACKGROUND AND OBJECTIVE Premature ventricular contraction is associated to the risk of coronary heart disease, and its diagnosis depends on a long time heart monitoring. For this purpose, monitoring through Holter devices is often used and computational

Quetiapine-induced frequent premature ventricular contraction

General Hospital Psychiatry, 2012
A 17-year-old female diagnosed with bipolar II disorder was treated for emotional lability with quetiapine. Two-lead electrocardiography revealed frequent monomorphic premature ventricular contraction (PVC) during an electroencephalography examination.

Fluctuations in premature ventricular contraction burden can affect medical assessment and management.

Heart Rhythm, 2019
BACKGROUND Frequent premature ventricular contractions (PVCs) can cause disabling symptoms and decrease left ventricular ejection fraction. PVC burden, typically quantified by a 24-hour monitor, is one of the factors that determines the clinical ...

Premature ventricular contractions in normal children

The Journal of Pediatrics, 1978
To document the assumed benign prognosis of premature ventricular contractions in children, we followed 17 patients with PVCs and without other heart disease for a mean of seven years (range one to 19 years). Data were collected from the history, physical examination, 15-lead ECG, and treadmill exercise test.

Premature ventricular contraction diurnal profiles predict distinct clinical characteristics and beta‐blocker responses

Cardiovascular Electrophysiology, 2019
Frequent premature ventricular complexes (PVCs) can lead to symptoms, such as cardiomyopathy and increased mortality. Beta‐blockers are recommended as first‐line therapy to reduce PVC burden; however, the response is unpredictable.

Summit Premature Ventricular Contractions

2020
Outflow tract PVCs can be accessible in the majority of cases. PVCs that originate in the left ventricular summit may be difficult to target with ablation directly. Ablation in the pulmonary cusp is feasible but should be carefully performed.
