Acute myocarditis presenting as accelerated junctional rhythm in Graves’ disease: A case report

Figure 1 Electrocardiography showed an accelerated junctional rhythm. No sinus P waves were found, the heart rate was 91 beats per minute, within 60-100 beats per minute, and ST-segment depression was seen in all leads. Accelerated junctional rhythm could be seen in patients with acute myocarditis.

Figure 3 Cardiac magnetic resonance showed myocardial edema in the lateral wall.

Figure 4 Cardiac magnetic resonance showed intramyocardial and subepicardial late gadolinium enhancement in the lateral apex, anterolateral, and inferior lateral segments of the ventricle.
