The corrected QT (QTc) interval is a strong predictor of ischaemic heart disease and cardiovascular mortality. It may trigger lethal arrhythmias and sudden death. Risk factors include electrolyte disorders, medications, prior cardiovascular disease and genetic predisposition. We previously demonstrated that QTc intervals are prolonged in patients hospitalised with pneumonia, regardless which antibiotics were given. It is unclear whether QTc prolongation is associated with pneumonia itself or whether it occurs with other infections.
