Frequent premature ventricular contractions.
Premature ventricular contractions (PVCs) are considered normal in many circumstances but can act as markers to other cardiac disease such as cardiomyopathy and ischemic heart disease. This case is presented to illustrate frequent PVCs as a marker for serious heart disease.
متن کاملCorrelation of cardiac magnetic resonance imaging and electrophysiology study findings among patients with frequent premature ventricular contractions
Despite inclusion in the diagnostic criteria for arrhythmogenic right ventricular cardiomyopathy, this study of 87 consecutive patients with isolated frequent LBBBmorphology PVCs and high PVC burden (mean 19%) demonstrated only a rare association with CMR diagnostic criteria for ARVC, no cases of ARVC diagnosis, no association of minor wall motion abnormalities (hypokinesis) with markers of ARV...
متن کاملRisk Stratification in Frequent Ventricular Extrasystoles: The Importance of Cardiac Magnetic Resonance
Ventricular tachycardia (VT) has a direct relationship with sudden cardiac death (SCD) and risk stratification is essential for further treatment. In a context of a structural normal heart, idiopathic VT is the principal suspicion. Cardiac magnetic resonance (CMR) is a powerfull tool to evaluate the anatomic substrate of ventricular arrhytmias. Myocarditis is a frequent cause of a arrhytmias, a...

متن کاملPremature Ventricular Contractions and Non-sustained Ventricular Tachycardia: Association with Sudden Cardiac Death, Risk Stratification, and Management Strategies
Premature ventricular contractions (PVCs) and non-sustained ventricular tachycardia (NSVT) are frequently encountered and a marker of electrocardiomyopathy. In some instances, they increase the risk for sustained ventricular tachycardia, ventricular fibrillation, and sudden cardiac death. While often associated with a primary cardiomyopathy, they have also been known to cause tachycardia-induce...
