Mildly reduced left ventricular ejection fraction
A small reduction in the fraction of blood pumped from the left ventricle with each cardiac cycle. The normal range in adults is at least 50 percent, and a mild reduction is defined as 40-49 percent. [from HPO]
Short QT syndrome type 3
Short QT syndrome is a cardiac channelopathy associated with a predisposition to atrial fibrillation and sudden cardiac death. Patients have a structurally normal heart, but electrocardiography (ECG) exhibits abbreviated QTc (Bazett's corrected QT) intervals of less than 360 ms (summary by Moreno et al., 2015). For a discussion of genetic heterogeneity of short QT syndrome, see SQT1 (609620). [from OMIM]
