摘　　要：目的:分析老年疑似房性期前收缩(房早)病人动态心电图诊断窦性心律不齐Lorenz-RR散点图特征。方法:对137例60岁以上老年疑似房早病人的动态心电图检查结果进行Holter记录,采用Holter软件描绘散点图,获得窦性心律不齐的Lorenz-RR散点图,并加以汇总归纳。结果:137例疑似房早病人经动态心电图诊断为窦性心律不齐,病人Holter Lorenz-RR散点图特征分类如下:137例病人中58例(42.3%)呈斜“Y”状;33例(24.1%)呈“棒状扩张型”;29例(21.2%)散点图呈“棒状”;13例(9.5%)为“不规则状”;2例(1.5%)呈现“纵向分离”;2例(1.5%)呈现“横向分离合并纵向分离”。结论:动态心电散点图对老年疑似房早病人窦性心律不齐的鉴别诊断更敏捷、更准确,具有较高的临床应用价值。Objective:To analyze the characteristics of Lorenz-RR scatter plot in elderly patients with suspected atrial premature beats diagnosed as sinus arrhythmia by dynamic electrocardiogram.Methods:The results of dynamic electrocardiogram examination of 137 elderly patients over 60 years old with suspected atrial premature beats were recorded by Holter.The Lorenz-RR scatter plot of sinus arrhythmia was obtained by using Holter software and summarized.Results:The 137 patients with suspected atrial premature beats were diagnosed as sinus arrhythmia by dynamic electrocardiogram.The characteristics of Holter Lorenz-RR scatter plot were classified as follows:oblique“Y”shape was found in 58 cases(42.3%)of 137 patients,“rod-shaped dilatation”was found in 33 cases(24%),“rod-shaped”was found in 29 cases(21.2%),“irregular shape”was found in 13 cases(9.5%),“vertical separation”was found in 2 cases(1.5%),and“transverse separation combined with longitudinal separation”was found in 2 cases(1.5%).Conclusions:The dynamic electrocardiogram scatter plot is more convenient and accurate for the detection of sinus arrhythmia in elderly patients with suspected atrial premature beats,and has high clinical application value.
