Abstract: Objective To evaluate whether quantitative co l or kinesis （QCK） can detect the changes of regional left ventricular systolic and diastolic function under experimental conditions.Methods The echocardiography examinations were performed in 10 d ogs to obtain systole and diastole color kinesis images both at SAX and A4C befo re and after every procedure followed: ①Ligating the inferior vein with stenost ic its diameter 30%;②Ligating the ascending aortic with stenostic its diameter 30%. All the stored digital loops above were reviewed by Echo View computer syst em with QCK software. The regional area changes both of systolic and diastolic ( RACs, RACd),the mean times of systolic and filling would be calculated automatic ally. Results Out of 120 screened color kinesis image frames, 108 ( 90%) with high quality that adequately tracking above 80% endocardial boundary. ①Control condition: The values of RACs ［from （38.00±11.29）% for b -lt to （76.33±14.52）% for ant］ and RACd［(45.43±19.75)% for b-lt to （77.50±14.72）% for ant］ were both different in each se gment . The values got from SAX view were higher. Ts was from（103.40±29.48） ms to （157.44±11.29）ms, and td was from （133.22±21.67）ms t o （170.86±39.51）ms.② Loading condition: After the ligation of inferi or vein, most of RACs(67%) and RACd(75%) were decreased in all segments without changing of global function, ts shorted(83%) and td(75%) prolonged. The changing continued with the ligation of ascending aortic.Conclusions QCK technique can accurately evaluate the LV regiona l systolic and diastolic function under loading, ischemia, and therapy condition s.
