In 92 patients affected from chronic obstructive pulmonary disease (C.O.P.) undergoing spirometric evaluation, the ability of the Pipberger computer program for electrocardiographic interpretation to predict the presence of pulmonary disease with or without right ventricular hipertrophy was compared with that of the manually measured conventional and orthogonal (Frank system) electrocardiogram. The patients were classified as having mild, moderate and severe C.O.P. on the basis of spirometric data. Each system predicted the presence of C.O.P. with low sensitivity. P voltage in D2 greater than or equal to 2 mm (27,1%) and R/S voltage ratio in V5-V6 greater than or equal to 1 (22,8%) were the single conventional criteria more frequently satisfied. Results for 3 lead manual readings were only slightly lower: recognition rate of the R/S voltage ration in x lead less than or equal to 1,3 was 15,7%. The Pipberger program probabilistic answers were divided in "completely" and "partially" correct. Combined completely or partially correct diagnoses were made by the program 14,3% of patients with mild C.O.P., 17,2% of moderate and 48,8% of severe C.O.P. These results suggests that the Pipberger program has at least similar ability to predict C.O.P. compared with the 12 lead and orthogonal manually measured electrocardiogram.
在92例接受肺活量测定评估的慢性阻塞性肺疾病（C.O.P.）患者中，将Pipberger计算机程序对伴有或不伴有右心室肥厚的肺部疾病的心电图解释预测能力与手动测量的传统及正交（Frank系统）心电图的预测能力进行了比较。根据肺活量测定数据，将患者分为轻度、中度和重度C.O.P.。每个系统对C.O.P.存在的预测敏感性都较低。D2导联中P波电压大于或等于2mm（27.1%）以及V5-V6导联中R/S电压比大于或等于1（22.8%）是最常满足的单一传统标准。3导联手动读数的结果仅略低：x导联中R/S电压比小于或等于1.3的识别率为15.7%。Pipberger程序的概率性答案分为“完全”和“部分”正确。该程序对轻度C.O.P.患者、中度C.O.P.患者和重度C.O.P.患者做出完全或部分正确诊断的比例分别为14.3%、17.2%和48.8%。这些结果表明，与12导联和正交手动测量的心电图相比，Pipberger程序预测C.O.P.的能力至少相似。
