Abstract
Objective To explore the features and formation principle of ECG scatterplot of interpolated premature beat, and thus to lay foundations for quickly analyzing ambulatory electrocardiography(AECG).Methods Typical cases of interpolated premature beat were selected and morphological characteristics of their ECG scatterplots were analyzed.By dynamic mapping and trajectory tracking functions of "geometric sketchpad" software, the scatterplot model was established.We summarized the ECG scatterplot features of interpolated premature beat combining the characteristics of practically recorded ECG scatterplots and the mathematical model.Results The actually recorded ECG scatterplots were very similar to the mathematical model.Conclusion The ECG scatterplot of interpolated premature beat has obvious features and a very strong regularity.The joint application of Lorenz scatterplot and difference scatterplot is effective in rapidly recognizing interpolated premature beat and its frequency on AECG as well as finding the induced disruptive PR interval prolongation and the prolonged amount.关键词
