Figure 2: Dynamic electrocardiogram changes during intravenous administration of adenosine. (a) Resting electrocardiogram: ST-segment depression in leads V3–V6 <0.05 mV and slightly T-wave inversions; (b) ECG showed settling of ST segment in leads V3–V6 and T-wave inversions became deeper; (c) ST-segment depression in leads V3–V6 has become 0.1–0.3 mV and T-wave developed coronary T-wave inversions; (d) ECG started to reveal premature ventricular contraction; (e) Heart rate and ECG ST-segment depression gradually recovered to the baseline. ECG = Electrocardiogram
