The analysis of the Lorenz plot with frequent atrial premature failing beats
Objective To explore the Lorenz plot characteristics of frequent atrial premature failing beats,laying the foundation for rapid diagnosis of related cases.Methods The typical cases with frequent atrial premature failing beats were selected,the change pattern of RR interval was analyzed,and the Lorenz plot characteristics of frequent atrial premature failing beats were summarized.Results In the Lorenz plot,the anterior point of atrial premature failing beats is located in the slow deceleration area,the posterior point of atrial premature failing beats is located in the slow acceleration area,the two are roughly symmetrical with the 45° line,and the bigeminy of atrial premature failing beats is located in the distal end of the 45° line.Conclusions The Lorenz plot with frequent atrial premature failing beats has obvious characteristics and strong regularity,and the electrocardiogram diagnostic physician can use the Lorenz plot to make rapid differential diagnosis.
