【 摘 要 】

The purpose of this research was to compare the accuracy of newly described Pwave-related parameters (P wave area, Macruz index and mean electrical axis) withclassical P wave-related parameters (voltage and duration of P wave) for the assessment ofleft atrial (LA) size in dogs with degenerative mitral valve disease. One hundredforty-six dogs (37 healthy control dogs and 109 dogs with degenerative mitral valvedisease) were prospectively studied. Two-dimensional echocardiography examinations and a6-lead ECG were performed prospectively in all dogs. Echocardiography parameters,including determination of the ratios LA diameter/aortic root diameter and LA area/aorticroot area, were compared to P wave-related parameters P wave area, Macruz index, mean electrical axis voltage and duration of Pwave. The results showed that P wave-related parameters (classical and newly described)had low sensitivity (range=52.3 to 77%; median=60%) and low to moderate specificity(range=47.2 to 82.5%; median 56.3%) for the prediction of left atrial enlargement. Theareas under the curve of P wave-related parameters were moderate to low due to poorsensitivity. In conclusion, newly P wave-related parameters do not increase the diagnosticcapacity of ECG as a predictor of left atrial enlargement in dogs with degenerative mitralvalve disease.
