ECG at admission and at 24 hours. A) ECG on admission: sinus rhythm with a frequency of 61 beats per minute (bpm), the axis was 30 , the PR segment lasted for 0.19 milliseconds (ms), the QRS complex for 100 ms and there was a 0.1 mV elevation of the ST segment in the II and aVF derivations, and a 0.2 mV elevation in the V3, V4, V5 and V6 derivations. B) ECG at discharge: the elevation of the ST segment was still present and the T waves in the V3, V4, V5 and V6 derivations were beginning to become negative.

The electrocardiogram (ECG) done at admission showed sinus rhythm of 61 beats per minute (bpm), with an axis of 30o, the PR segment of 0.19 milliseconds (ms), the QRS duration of 100 ms and a 0.1 mV elevation of the ST segment in II and aVF, and a 0.2 mV elevation in the V3, V4, V5 and V6 (Figure 1).
