| Popis: | This report describes results of computer analysis of Frank lead electrocardiographic data recorded during a population study. Computer and visual measurements were compared in records from the same subjects. The prevalence of several Frank lead findings and standard lead electrocardiographic criteria were compared in subjects without clinical evidence of cardiac disease, in subjects with a clinical history of myocardial infarction or other evidence of cardiovascular abnormality, and in an unclassified group. A multivariate statistical method was used to evaluate the capability of several sets of Frank lead variables to identify records from subjects with standard lead electrocardiographic abnormalities and to discriminate between normal subjects and those with cardiovascular abnormalities. Most, but not all, records from subjects with standard lead electrocardiographic abnormalities were identified with the use of Frank lead variables. A multivariate statistic using four points during the ST-T wave may be more effective than some standard lead ST-T findings in discriminating between normal subjects and those with cardiovascular abnormalities. Other Frank lead variables did not give better discrimination between these two groups than standard lead criteria. More subjects in the unclassified group had Frank lead findings outside normal limits than had abnormalities in the standard leads; further study will be necessary to determine whether this indicates that these Frank lead variables have higher sensitivity or lower specificity for cardiac disease. |
