Frequent premature ventricular complexes (PVCs) can be an indicator of structural heart disease.
This article was published in the following journal.
Name: Heart rhythm
In an ideal world, primary prevention defibrillators would be placed only in patients who will suffer from life-threatening ventricular arrhythmias in the future. Since electrophysiologists cannot pre...
The aim of this study was to use non-invasive electrocardiographic imaging (ECGI) to study the electrophysiological properties of right ventricular outflow tract (RVOT) in patients with frequent prema...
Frequent premature ventricular contractions (PVCs) can cause cardiomyopathy (CM). Post-extrasystolic potentiation and irregularity have been in implicated as triggers of PVC-CM. Since both phenomena c...
Premature ventricular contractions (PVCs) are arrhythmias with presentation ranging from asymptomatic and benign to symptomatic, frequent and capable of inducing cardiomyopathy. Work in the late 1970s...
To test the feasibility of clot volume and right ventricular dysfunction for risk stratification of acute pulmonary embolism (APE) patients.
With this project the investigators aim to investigate whether premature ventricular complexes (PVC) have a prognostic significance in persons without structural heart disease. Further the...
To evaluate the effectiveness and safety of catheter ablation of frequent symptomatic PVCs in the pediatric population as first-line therapy compared with antiarrhythmic drugs.
Carvedilol is known to be effective in reducing ventricular arrhythmias and mortality in patients with heart failure. It is suggested that one of the mechanisms is its ability to block sto...
Premature ventricular contractions (PVCs) coexist in patients with heart failure (HF) and LV dysfunction. Frequent PVCs have shown to induce a reversible cardiomyopathy (PVC-CM). This cli...
Current navigation systems incorporate algorithms for automatic identification of local activation time (LAT). However, data about their utility and accuracy in premature ventricular compl...
A type of cardiac arrhythmia with premature contractions of the HEART VENTRICLES. It is characterized by the premature QRS complex on ECG that is of abnormal shape and great duration (generally >129 msec). It is the most common form of all cardiac arrhythmias. Premature ventricular complexes have no clinical significance except in concurrence with heart diseases.
A group of cardiac arrhythmias in which the cardiac contractions are not initiated at the SINOATRIAL NODE. They include both atrial and ventricular premature beats, and are also known as extra or ectopic heartbeats. Their frequency is increased in heart diseases.
A form of CARDIAC MUSCLE disease, characterized by left and/or right ventricular hypertrophy (HYPERTROPHY, LEFT VENTRICULAR; HYPERTROPHY, RIGHT VENTRICULAR), frequent asymmetrical involvement of the HEART SEPTUM, and normal or reduced left ventricular volume. Risk factors include HYPERTENSION; AORTIC STENOSIS; and gene MUTATION; (FAMILIAL HYPERTROPHIC CARDIOMYOPATHY).
A type of cardiac arrhythmia with premature atrial contractions or beats caused by signals originating from ectopic atrial sites. The ectopic signals may or may not conduct to the HEART VENTRICLES. Atrial premature complexes are characterized by premature P waves on ECG which are different in configuration from the P waves generated by the normal pacemaker complex in the SINOATRIAL NODE.
Pathological processes of the VESTIBULAR LABYRINTH which contains part of the balancing apparatus. Patients with vestibular diseases show instability and are at risk of frequent falls.
