Usefulness of electrocardiography QT interval for prediction of left ventricular diastolic dysfunction: a cross-sectional study.

Unlabelled: Heart failure (HF) is a leading cause of morbidity and mortality worldwide, with projections showing a further rise in incidence, impacting a decline in quality of life and the costs incurred in its diagnosis and treatment. The authors aim to establish the correlation between the prediction of left ventricular diastolic dysfunction based on a change in QT wave intervals.

Methods: A cross-sectional at Holy-family Hospital, Rawalpindi Medical University, Pakistan.
