Premature Ventricular Complex-induced Cardiomyopathy

Arrhythmia & Electrophysiology Review, 2018
Premature ventricular complex-induced cardiomyopathy is a potentially reversible condition in which left ventricular dysfunction is induced by the occurrence of frequent premature ventricular complexes (PVCs). Various cellular and extracellular mechanisms and risk factors for developing cardiomyopathy in this context have been suggested but the exact ...

Ventricular dyssynchrony as a cause of structural disease in the heart of Dorper sheep

Onderstepoort Journal of Veterinary Research, 2004
Ventricular dyssynchrony is a disturbance of the normal, organized electromechanical coupling of the two ventricles. This condition has many causes, such as left bundle branch block, ventricular preexcitation, right ventricular pacing and right ...

Association of tricuspid annular plane systolic excursion (TAPSE) with survival time in Boxer dogs with ventricular arrhythmias [PDF]

, 2015
BACKGROUND: Tricuspid annular plane systolic excursion (TAPSE) is a useful estimate of right ventricular function in humans. Reference intervals for dogs have been generated, but the value of measuring TAPSE in other diseases, or investigating the ...

Causes of prehospital misinterpretations of ST elevation myocardial infarction [PDF]

, 2016
Objectives: To determine the causes of software misinterpretation of ST elevation myocardial infarction (STEMI) compared to clinically identified STEMI to identify opportunities to improve prehospital STEMI identification.

Long-term effect of continuing sports activity in competitive athletes with frequent ventricular premature complexes and apparently normal heart.

American Journal of Cardiology, 2013
The long-term outcome of athletes with frequent ventricular premature complexes (VPCs) and apparently normal heart has not been fully clarified. To evaluate the clinical and prognostic significance of VPCs and the influence of continuing sports activity ...

Modifiable predictors of ventricular ectopy in the community [PDF]

, 2018
Background Premature ventricular contractions (PVCs) predict heart failure and death. Data regarding modifiable risk factors for PVCs are scarce. Methods and Results We studied 1424 Cardiovascular Health Study participants randomly assigned to 24-hour ...

Arrhythmia induction using isoproterenol or epinephrine during electrophysiology study for supraventricular tachycardia [PDF]

, 2018
Background Electrophysiology study (EPS) is an important part of the diagnosis and workup for supraventricular tachycardia (SVT). Provocative medications are used to induce arrhythmias, when they are not inducible at baseline. The most common medication

R-from-T as a common mechanism of arrhythmia initiation in long QT syndromes [PDF]

, 2019
Background: Long QT syndromes (LQTS) arise from many genetic and nongenetic causes with certain characteristic ECG features preceding polymorphic ventricular tachyarrhythmias (PVTs).
