Cardiac manifestations of human immunodeficiency virus (HIV) and acquired immunodeficiency syndrome have become increasingly important causes of morbidity and mortality. We investigated HIV-positive patients to determine the effects of HIV infection, antiretroviral drugs, and identifiable confounders on QTc prolongation.
