Our results indicate that QT and JT dispersions are related to the echocardiographic degree of MVP and mitral leaflet thickness. The echocardiographic assessment of the severity of the prolapse may help to identify a subgroup of patients at increased risk of life-threatening arrhythmias.

Stimulation from the apex of the right ventricle leads to regional disturbances of the adrenergic innervation of the left ventricular myocardium, as assessed by I(123)-MIBG activity.
