Abstract
Objective To observe the effects of coronary angiography ( CAG ) on QRS duration. Methods A retrospective analysis was done in 125 patients given CAG from June 2011 to April 2012, in whom 98 were diagnosed as coronary artery disease ( CAD ) ( lesion group ), including 33 cases of 1 - vessel disease, 38 of 2 - vessel, 27 of 3 - vessel, and 27 normal subjects ( control group ). The parameters of all subjects were collected and the changes of QRS duration and their influencing factors were compared before and after CAG operations. Results QRS duration was longer after operation than before operation [ ( 3. 18 ± 5. 30 ) ms, 95% CI ( 2.25, 4. 12 ), P = 0. 000 ]. The prolongation of QRS duration ( QRS variability, AQRS ) increased in lesion group as compared with that in control group after operation ( ( 3. 96 ±5. 70 ) ms vs. ( 0. 37 ± 1. 47 ) ms, P <0. 05 ]. The prolongation of QRS duration was positively correlated with the number of diseased coronary arteries ( CA ) after CAG operations [ B = 2. 455 , 95% CI ( 1. 764, 3. 147 ), P = 0. 000 ]. Conclusion CAG can increase the prolongation of QRS duration. QRS duration prolongation is correlated with degrees of CA lesions after CAG operations.关键词
