A comprehensive list of conditions and drugs that may prolong the QT interval, and cause torsade de pointes (TdP) and long QT syndrome (LQTS) is presented below. With regards to drugs, the risk of QT prolongation and TdP varies markedly across the list but tends to be rather similar within a drug class. While the risk of TdP is well-defined for many of these agents, many are classified as QT-prolonging solely based on their drug class or presumed pharmacodynamic effects. We provide a direct PubMed search for each drug and we recommend the reader to use this link to assess the literature.
