Abstract：Vasospastic angina (VSA) is usually seen in patients with normal coronary artery or no severe coronary artery stenosis. This paper mainly focuses on the ECG changes of VSA patients. Typically ECG changes are usually observed in VSA patients. Peaked and symmetrical T waves appeared in the ECGs of nearly half of them; progressive elevating ST segment appeared if the spasm continued and then gradually fell down after a few minutes. The ECG changes associated with ST-segment elevation also included R-wave heightening and S-wave diminution; the rise of TQ-segment slope, and electrical alternations of ST-segment elevation and T-wave deeply inversion were observed in some cases. In addition, ventricular arrhythmia is usually accompanied with VSA.
