Comparison of slow blood flow phenomenon on coronary arteriogram with findings on dynamic electrocardiogram

Objective To investigate the relation between slow blood flow phenomenon on coronary arteriogram and findings on dynamic electrocardiogram. Methods Forty-three patients with chest pain admitted to our hospital underwent coronary arteriography in January 2006-May 2009（CAG）,which showed slow blood flow phenomenon.Thirty patients with normal CAG served as controls.Dynamic electrocardiography was performed the day after coronary arteriography.The results were analyzed. Results Of the 43 patients,26（60.5%） showed depression in ST segment,32（67.4%） showed alterations in T wave,and 21（48.8%） showed frequent ventricular premature or non-sustained ventricular tachycardia.Frequent ventricular premature or non-sustained ventricular tachycardia was more frequent in patients with abnormal CAG than in those with normal CAG（P＜0.01）. Conclusion The number of blood vessels involved in coronary slow flow phenomenon is related with frequent ventricular premature or non-sustained ventricular tachycardia.
