Premature Ventricular Contraction–Induced Cardiomyopathy [PDF]

Clinical Cardiology, 2015
AbstractPremature ventricular contractions are of common occurrence in routine clinical practice. Though generally perceived as of benign consequence in healthy people in the absence of heart disease, their presence can be a harbinger of fatal ventricular tachyarrhythmia in individuals with structural heart disease.

Evaluation of Brain natriuretic peptide in premature heart contraction patients [PDF]

Journal of Bioscience and Applied Research
The current study was designed to study biomarkers of premature atrial and ventricular contraction by using brain natriuretic peptide (BNP). The study was performed on patients' clinics and private laboratories in AL-Najaf Governorate / Iraq from August ...

A Review: Detection of Premature Ventricular Contraction Beat of ECG [PDF]

, 2020
: ECG signal is a periodic signal that gives information about the heart activity. A lot of information about normal and abnormality about the heart can be obtained from the ECG signal. Premature ventricular contractions (PVCs) are the ectopic beats that

Implantable Cardioverter‐Defibrillator Therapy in Arrhythmogenic Right Ventricular Dysplasia/Cardiomyopathy: Predictors of Appropriate Therapy, Outcomes, and Complications

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2017
BackgroundArrhythmogenic right ventricular dysplasia/cardiomyopathy is characterized by ventricular arrhythmias and sudden cardiac death. Once the diagnosis is established, risk stratification to determine whether implantable cardioverter‐defibrillator ...

Radiofrequency ablation can reverse the structural remodeling caused by frequent premature ventricular contractions originating from the right ventricular outflow tract even in a normal heart

Clinics, 2013
OBJECTIVE: The aim of this study was to evaluate whether frequent premature ventricular contractions originating from the right ventricular outflow tract remodel the cardiac structure and function in patients with a “seemingly normal heart” and whether ...

Improved ventricular function during inhalation of PGI(2) aerosol partly relies on enhanced myocardial contractility [PDF]

, 2005
Inhaled prostacyclin (PGI(2)) aerosol induces selective pulmonary vasodilation. Further, it improves right ventricular ( RV) function, which may largely rely on pulmonary vasodilation, but also on enhanced myocardial contractility.

Frequent Ventricular Premature Complex-Induced Decompensated Heart Failure

, 2015
Asymptomatic premature ventricular beats are most common presentation form of arrhyth-mia observed in patients with or without structural heart disease. In long term, frequent pre-mature ventricular beats can lead left ventricule failure in structurally ...

Left ventricular dyssynchrony as marker of early dysfunction in premature ventricular contraction-induced cardiomyopathy

Frontiers in Cardiovascular Medicine, 2022
BackgroundStrain imaging has been suggested as a tool to detect early left ventricular (LV) dysfunction due to frequent premature ventricular contractions (PVCs) in patients with preserved LV ejection fraction (EF).

Endothelin and increased contractility in adult rat ventricular myocytes. Role of intracellular alkalosis induced by activation of the protein kinase C-dependent Na(+)-H+ exchanger [PDF]

, 1991
Endothelin, a 21-amino acid vasoactive peptide, is among the most potent positively inotropic agents yet described in mammalian heart. Having demonstrated that endothelin's inotropic effect is due, in part, to an apparent sensitization of cardiac ...
