CORRECTED QT DISPERSION IN CHILDREN WITH ISOLATED UNCOMPLICATED MITRAL VALVE PROLAPSE
Mitral valve prolapse (MVP) is a relatively frequent valvular abnormality. In both children and adults with MVP, an increased incidence of ventricular arrhythmias has been reported. QT dispersion, defined as the difference in duration between the longest QT interval and the shortest one, for a given set of electrocardiographic leads has been proposed as a sign of regional difference in card...
متن کاملMarcus-gunn phenomenon with- mitral valve prolapse
Marcus-gunn phenomenon is a congenital and sometimes hereditary anomaly, in which a ptotic eyelid retracts momentarily when the mouth is open, or the jaw is moved. These associated movements attributed to abnormal connections between the central mechanisms innervating the pterygoid and elevator muscles. Sometimes this anomaly is associated with dual,s retraction syndrome, duplex kindneys and ur...
متن کاملAssociation between Body Mass Index and Mitral Valve Prolapse
Introduction: Body mass index (BMI) can affect cardiac morphology; however, the relationship between BMI and valvular heart diseases has not been thoroughly evaluated. This study aimed to determine the relationship between BMI and mitral valve prolapse (MVP) as one of the most common valve diseases worldwide. It can help us to better understand pathophysiology of this common disease. Materials ...
متن کاملE VALUATION OF ADENYLATE CYCLASE ACTIVITY IN MITRAL VALVE PROLAPSE
The term mitral valve prolapse (MVP) is used for a particular subset of patients with hyperadrenergic dysautonomia. It occurs when part of a leaflet or both leaflets of the mitral valve extend above the plane of the atrioventricular junction during ventricular systole. The adenylate cyclase activity in MVP dys-autonomia was studied by extraction of enzyme from the erythrocytes from 62 norma...
