OBJECTIVE: To evaluate whether it is possible on the basis of ECG examination to judge the haemodynamic impact of @entity1151 . METHOD: To compare by retrospective analysis of hospital documentation of @entity1 at the medical department the assessed ECG changes with the echocardiographic finding of @entity120 and @entity1001 . As positive an ECG finding was evaluated involving changes of the ST-T segment in VI-V4, S1Q3T3 negative or @entity714 ( @entity714 ). As a positive echocardiographic finding the authors evaluated the size of the right ventricle above 30 mm or the shape of the acceleration curve in the outflow tract of the right ventricle corresponding to @entity120 . RESULTS: The authors analyzed 179 @entity1 with clinically diagnosed @entity1151 during the period from Jan. 1 1996 till Dec. 31 2000. A positive ECG finding was recorded in 103 @entity1 , i.e. 57.5%. Echocardiographic examination was made in 112 and 65 of them had a positive ECG. An echocardiographic finding of @entity120 or dilatation of the right ventricle was recorded in 92 @entity1 . In case of positivity of at least one ECG finding an ECG sensitivity of 62% and specificity of 60% was found. In case of changes in the ST-T segment in V1-V4 the sensitivity and specificity was 47% and 70% resp., for S1Q3T3 negative 27% and 80% resp. and PRT @entity42461 % and 90% resp. CONCLUSIONS: The absence of ECG changes does not rule out serious @entity1151 . The finding of typical ECG changes is very frequently associated with @entity120 , @entity1001 and a serious haemodynamic finding.
