QTc prolongation in HHD merits ECG vigilance; leaves open outcome impact and need for prospective trials.
Background: The study assessed the prevalence of QT interval prolongation and identified its associated factorsMethods: The study was cross-sectional in design. Subjects confirmed on echocardiography to have HHD were recruited consecutively from 3 echocardiography laboratories in the Kano City, Nigeria, over 7 months. Prolonged QTc was defined as QTc > 440 ms in males and > 460 ms in females, or more than 500ms in both sexes in the presence of complete bundle branch block. A p-value of
