Replacement of cardiac valves in the pediatric patients is infrequent compared with in adult for the treatment of diseased heart valve. Furthermore, uncertainties regarding the long term fate of prosthetic value and effects of a fixed-orifice walve in the growing children are the main concern in pedriatric patients. Between January 1974 and October 1979, in 10 children, 15years or younger, cardiac valves were replaced becasuse of congenital or acquired valvular heart diseases in the Department of Thoracic & Cardiovascular Surgery, Seoul National University Hospital. There were 8 mitral valves, one aortic valve and one mitral and aortic valve replaced. Indications for valve replacement were intractable congestive heart failure or apperently progressing cardiac symptoms and signs. Early postoperative death was noticed in one due to arrythmia, and late postoperative death in one due to cerebral thromboembolism after 9 months of double valve replacement. All Survlvors showed clinical improvement and good cardiac condition during postoperative and follow-up period till now.

Purpose: This is a methodological study investigating the validity and reliability of the rehabilitation nursing competency measurement tools by clinical career stage for rehabilitation nurses. Methods: Data were collected from 475 rehabilitation nurses at 13 rehabilitation hospitals across South Korea. Questionnaires were organized based on the ARN (Association of Rehabilitation Nurses) competency model for professional rehabilitation nursing. We verified content validity, construct validity (using factor analysis), convergent validity (using correlation with clinical performance ability), and reliability. Results: The CVI (Content Validity Index) of the measurement tools were all above CVI=.75 except for one item for beginner. After analyzing the measurement tools, there were 7 factors for beginner, 6 factors for intermediate, and 4 factors for advanced. Clinical performance ability and rehabilitation nursing competencies indicated a positive correlation for every clinical career stage. The Cronbach's ⍺ of the tool by clinical career stage were found to be .97, .98, and .99 for beginner, intermediate, and advanced stages respectively. Conclusion This study verified validity and reliability of the measurement tools for rehabilitation nursing competency and provided an opportunity to present the competency for rehabilitation nursing according to clinical career stage.

Purpose: This exploratory study aims to identify the influence of clinical practice belonging, satisfaction with major, and work values on the level of career identity among nursing students. Methods: The subjects of this study are 251 senior students from three nursing departments located in a metropolitan city. Using SPSS 22.0, the study uses technical statistics, t-test, One-way ANOVA, correlation, and multiple regression analysis. Results: The average scores for clinical practice belonging, satisfaction with major, and work values were 3.61, 3.87, and 3.70 out of 5.00, respectively, and 2.85 out of 4.00 for career identity. The factors affecting students' career identity were clinical practice belonging, aptitude, satisfaction with clinical practice, satisfaction with major, indoor work, service and employment at hospitals with 40 percent being explained by these variables. Conclusion Through this study we found that clinical practice belonging has the greatest impact on career identity. In order to enhance clinical practice belonging, universities and clinical institutions need to develop new programs and curricula.

BACKGROUND: Idiopathic left ventricular tachycardia with a QRS pattern of right bundle branch block and left axis deviation that is sensitive to verapamil is electrophysiologically distinct arrhythmia entity but descriptions in pediatric ages are infrequent. This study attempted to describe the clinical presentation and dignostic clues from the surface ECG in children with idiopathic left venteicular tachycardia. METHODS: We retrospectively reviewed the medical records, electrocardiograms, Holter recordings, echocardiographic reports of 10 children with idiopathic left ventricular tachycardia who have been managed at Sejong General Hospital and Asan Medical Center, Seoul, Korea from January 1991 to July 1996. Follow-up periods are 2 months to 5 years(mean=26 months). RESULTS: 1) Age of tachycardia onset was 8 months to 14 years(median=4.3 years). In 3 children tachycardia began from infancy. The main complaint in older children was palpitation and chest discomfort but young childen complained abdominal pain during tachycardia attack. Tachycardia was paroxysmal and sustained. Tachycardia responded to intravenous use of verapamil in 9 patients and was controlled by chronic verapamil medication in 6 patients. 2 patients were well without medication. Radiofrequency catheter ablation was done in an adolescent patient successfully. 2) In sinus rhythm, surface ECG showed normal QRS axis and normal QRS morphologies in all patients. During ventricular tachycardia, the heart rate was 183 to 270 beats/min. The taxhycardia of RBBB morphology was observed in all patients. The mean QRS duration was 109+-12ms and the QRS axis was -50* to -90*. Themean RS interval was 60+-12ms. AVdissociation was found on surface RCG in all patients and confirmed in 4 patients by transesophageal ECG. We tried rapid transesophageal atrial pacing in 3 patients and could induce and terminate the ventricular tachycardia. CONCLUSIONS: Idiopathic left ventricular tachycaedia is rare in childhood and is seen from infancy. Idiopathic left ventricular tachycardia is generally benign but occasionally causesmyocardial dysfunction. Idiopathic ventricular tachycardia with a QRS pattern of right bundle branch block amd left axis deviation that is sensitive to verapamil in children should not be confused with supraventricular tachycardia with aberrancy and most helpful diagnostic clue is AV dissociation in surface ECG.
