Analysis of QT interval in patients with Idiopathic mitral valve prolapse

Objectives: The aim of study is to assess the relationship between QT interval and IMVP, finding of an explanation for some cases of sudden death, presenting the association of symptoms of IMVP and some types of arrhythmias. Methods: QTC intervals were measured in 43 patients with idiopathic mitral valve prolapse (11 men and 32 women with mean age 46±17 years). All patients underwent a clinical and echocardiographic examination, and ECG taking to assess the incidence of long QT in patients with IMVP. Results: The results reveal a higher incidence of prolonged QT interval in patients with IMVP ,36 of 43 patients, while only 2 of 38 as control group. In addition, there were an increase incidence of arrhythmias with prolongation of QT interval. Conclusion: This study indicates that the patients with IMVP at risk of arrhythmias, also these risks are higher in those patients with very long QT that may leads to serious ventricular arrhythmias.
