Abstract

This study aims to provide information on the parameter changes in the acute myocardial infarction model of a Chinese Rural Dog. All dogs were fixated in the conscious state and recorded in the prone position. The data were retrospectively analyzed. The P wave interval increased in the first 5 h and then reached the stable phase by the 77th day. T wave interval increased from the 10th to the 12th day, and after 16 days, the T wave interval in the intervention group became lower than that of the control group. Moreover, the amplitude of the T wave peaked at the 10th day and dropped to the preoperative level. The most obvious change of AO was 90 days after surgery. The AMI model of the Chinese Rural Dog was established and the ECG parameters (Pd, Pa, QRSd, QRSa, Td, Ta, PRd, and QTd), and myocardial enzymes (CK, CK-MB, LDH, and AST) changed significantly following AMI.
