Electrocardiogram at admission shows ST-segment elevation at the precordial leads (V2-V6), Q-wave, and subsequent T-wave inversion (V2-V5). These observations are consistent with acute anterior wall ST-segment-elevated myocardial infarction.

The electrocardiogram (ECG) results showed ST-segment elevation at the precordium leads (Fig. 1), and ST-segment elevation myocardial infarction (STEMI) was therefore suspected.
Angiography shows grade 3 thrombolysis in myocardial infarction flow. Angiography was performed 3 hours after the acute onset of chest pain. (A) The caudal view shows the left coronary artery including the left main artery, left descending artery, and circumflex artery, which are all normal. (B) The normal right coronary artery.

The CAG failed to show any significant stenosis in the large coronary artery (Fig. 2).
Electrocardiogram (ECG) findings support the diagnosis of ventricular tachycardia. The ECG, taken during a palpitation episode, shows the QRS deformity, which is not associated with P-wave, the main QRS complex upward at the avR lead, and a ventricular heart rate of 150 beats/min.

ECG revealed VT (Fig. 3).
