Abstract

A comparison betwen electrocardiographic and echocardiographic criteria of Lt. atrial enlargement was made in 40 cases who demonstrated left atrial enlargement either electrocardiographically or echocardiographically.
1) There were 20 cases with Lt. atrial enlargement by electrocardiographic criteria and echocardiographic criteria and 30 cases by echocardiographic criteria
2) Of 40 subjects, 19 cases were found to satisfy both electrocardiographic and echocardiographic critera of Lt. atrial enlargement at the same time.
3) 10 cases were consistent only with electrocardiographic criteria of Lt. atrial enlargement, but not with echocardiographic criteria
4) On the other hand, 11 cases of Lt. atrial enlargement consistent with echocardiographic criteria did not meet the electrocardiographic criteria
5) The respective predictive indices of electrocardiographic and echocardiographic criteria of Lt. atrial enlargement were:
Electrocardiographic criteria; positive: 65.52%,
Negative: 79.9%.
Echocardiographic criteria; Positive: 63.3%,
Negative: 89.13%.
