UNASSIGNED: @entity859 stress testing in conjunction with radionuclide myocardial perfusion imaging has become a common approach for the detection of @entity453 in @entity1 who are unable to perform adequate levels of exercise. However, specific electrocardiographic alterations during the test have been rarely described. Using a Chinese population, the aim of the present study was to provide a detailed electrocardiographic profile of @entity859 stress testing. The study population included 1,168 consecutive outpatients who had undergone @entity859 -induced stress myocardial perfusion imaging. Electrocardiographic data during and immediately following the @entity859 infusion were collected, and the corresponding myocardial perfusion images were assessed. During @entity859 infusion, 174 transient and 47 persistent arrhythmic events occurred in 110 @entity1 (9.42%). Furthermore, frequent premature @entity11706 occurred in 65 individuals and frequent @entity1540 were observed in 73 individuals. @entity713 ( @entity713 ) occurred in 75 @entity1 [first degree (I  ) @entity713 , 16; second degree (II  ) @entity713 , 58; third degree @entity713 , 1), while @entity9765 occurred in eight @entity1 . ST @entity308 emerged in 69 @entity1 . @entity1 with a baseline I   @entity713 had an increased risk of a II   @entity713 , and @entity1 exhibiting @entity308 were more likely to have a further depressed ST segment during the stress test (odds ratio, 28.68 and 5.01, respectively; both P<0.001). Following @entity859 infusion, 10 @entity1 (0.86%) exhibited newly occurred arrhythmic events. However, no @entity1 presented with acute @entity583 or sudden mortality. In conclusion, the results demonstrated that @entity859 infusion was a safe method, despite the relatively high incidence of arrhythmic events. The majority of @entity943 that occurred during infusion were transient, were reversible with the termination of infusion and did not indicate abnormal perfusion results.
