Диспластические синдромы и фенотипы в оценке изменений интервала QT при малых аномалиях сердца

Abstract

To assess relation of dysplastic syndromes and phenotypes to pathological QT interval in patients with minor cardiac anomalies, 128 patients aged 18–35 years were examined. A statistically significant increase in the prevalence of QT interval disorder was found. Pathological QT interval without clinical features was observed more frequently. Correlations were revealed between the QT interval disorder and myxomatous mitral valve prolapse, phenotype similar to Marfan syndrome, and benign joints hypermobility.
