case_images: 'Abnormal ECG.' This figure is a 12-lead ECG which was taken after resuscitation from cardiac arrest. It shows ST elevation at the J point in leads II, III, and aVF.

case_images: A 12-lead ECG revealed ST elevation at the J point in leads II, III, and aVF (Figure 1).
case_images: 'Right coronary artery: before and after.' This figure is a coronary angiogram containing 2 images (a, b). (a) Narrowing of the right coronary artery shortly after cardiac arrest. (b) How the narrowing of the same right coronary artery was almost completely restored immediately after administration of 400 micrograms of intracoronary nitrate.

case_images: ECG, was acute occlusive myocardial infarction, and she was transferred for emergency coronary angiography. ECG had normalized on arrival in the catheterization laboratory; however, coronary angiography showed considerable restriction of the right coronary artery (RCA) lumen (Figure 2(a)), accompanied by recurrent gross ST elevation on the ECG monitor. ST segments on ECG (Figure 2(b)). Severe vasospasm in the RCA was diagnosed as the primary problem due to the quick resolution of the dynamic ECG changes and near-normal coronary angiogram findings following nitrate administration.
case_images: 'Normalized ECG.' This figure is a 12-lead ECG which was taken the day after cardiac arrest. It shows a return to normal sinus rhythm and resolution of the inferior ST-segment elevation.

case_images: There were no recurrences of arrhythmia, and all subsequent resting ECGs showed a return to normal sinus rhythm (Figure 3).
