Syncope with QT interval prolongation and T-wave inversion: pulmonary embolism.

The patient presented with syncope, without chest pain and dyspnea. There was no peripheral edema or nervous system signs. The electrocardiogram (ECG) showed QT-interval prolongation with T-wave inversion in anterior and inferior leads. T-wave inversion in the right-sided precordial leads should prompt consideration of right ventricular overload. The patient underwent computed tomography of the chest that demonstrated pulmonary embolism. Ultrasonography of the veins of the lower limbs revealed an isolated calf vein thrombosis.
