Figure 1 Comparison of electrocardiograms during the myasthenic crisis. A: The electrocardiogram (ECG) was taken upon presentation in the emergency department and showed normal sinus rhythm, with no signs of pathology; B: The second ECG was taken at 4 h after presentation and showed ST-elevation in anterior leads (V1-V4) and lateral leads (I and aVL), with minimal reciprocal depressions in inferior leads (II and aVF) and new T-wave inversion in aVL; C: The third ECG was taken 1 d after presentation to the emergency department and showed evolving ST-elevations in anterior leads, with biphasic T-waves and new inverted T-waves in I, II, aVL and aVF.
