Figure 1.

First ECG, with the patient complaining of chest pain and dyspnea, showing ST depression in inferior and left precordial leads and elevation in V1 and VR (A). Second ECG, during the transfer to the hospital, showing minimal changes in ST segment (B). Third ECG, before the angiogram, with complete normalization of the repolarization changes (C). The difference in voltage and axis in limbs leads between the first ECG and the rest, probably due to a decrease in impedance secondary to the presence of liquid in the thorax during the immediate phase after near-drowning.
