Prolonged ST segment depressionSPECTBackground: It is generally perceived that the persistence of ST segment depression for more than 5 min after treadmill exercise testing (ETT) signifies a strongly positive test and predicts more severe ischemia and coronary artery disease. Aim: The aim of this ...
