Abstract：Objective Our study focused on gated myocardial perfusion imaging in the diagnosis of patients with left ven‐tricular dyssynchrony .Methods 47 cases with DCM underwent gated myocardial perfusion imaging ware enrolled .All ca‐ses were grouped according to the duration of QRS :QRS normal group and QRS duration extend group .35 cases of nor‐mal subjects in the same period were taken as normal control group .99m Tc‐MIBI myocardial perfusion imaging was conduc‐ted .AI were calculated ,and EF ,EDV and ESV was recorded .Each group was compared using ANOVA .P <0 .05 was used as a statistically significant difference .Results There were significant differences of EF ( P<0 .001) .QRS duration extened group :septum‐lateral contraction delays were observed in 13 cases ,and anterior‐posterior delays in 7 cases .AI was between 2 to 5 .QRS duration normal group :Interval‐septal contraction delays were observed in 2 cases ,AI were 2 , 3 respectively .AI difference between the two groups was statistically significant .Conclusion The method could observe and locate the coordination of left ventricular contraction intuitively ,and could be helpful in the diagnosis and treatment of ventricular dyssynchrony .
