[Congenital tricuspid insufficiency due to valvular dysplasia].

A case of congenital tricuspid incompetence in a 39 year old woman is reported. The patient, who was in suffering congestive heart failure, had no history of trauma, myocardial infarction, rheumatic fever, infective endocarditis. Right ventriculography and right atrial pressure recording both showed signs of severe tricuspid insufficiency. Echocardiography showed dilatation of the right ventricle and atrium, and the lack of normal systolic coaptation of anterior and septal tricuspid leaflets, while contrast echocardiography gave direct evidence of regurgitation. Valvular replacement with a bioprosthesis was carried out. The diagnosis of congenital tricuspid incompetence was confirmed at operation. The patient is asymptomatic at one year follow up.

[Usefulness of multicenter evaluation of the reliability of a program for automatic analysis in clinical electrocardiography].

The HP-5 program for computer analysis of the ECG has been evaluated as far as sensibility and specificity in a multicenter study. A consistent number of tracings were sampled according to a statistical formula and all measurements and statements given by the computer were checked in a standardized manner. The collected data were classified and computerized. The HP-5 program has shown a very high specificity for tracings classified as normal (0.7% of false negatives) and for those classified abnormal (no false positive), while the level of agreement between manual and computer readings of the tracings classified atypical or borderline, was fair (75%). It is concluded that the new program represents a significant step forward in the practical use of computerized ECG.

[Comparative evaluations between on-line and off-line in automatic electrocardiographic diagnosis and readings of the cardiologist].

The comparative evaluation of diagnosis, given on the same ECG by a cardiologist and by a computerized system HP 5600 C on line and off line, allowed us to specify for each diagnosis the agreement's degree between cardiologist and computerized reading and the disagreement's degree due to inadequate program and to "casual" errors of analysis.

[Multicenter study and clinical use of HP-5 program (author's transl)].

The HP-5 program for computer analysis of the ECG has been evaluated as far as sensibility and specificity in a multicenter study. A consistent number of tracings (850) were sampled according to a statistical formula and all measurements and statements given by the computer were checked in a standardized manner. The collected data were classified and computerized. The HP-5 program has shown a very high specificity for tracings classified as normal (0.7% of false negatives) and for those classified abnormal (no false positive), while the level of agreement between manual and computer readings of the tracings classified atypical or borderline, was practical of computerized ECG.
