We designed software system to detect intermittent arrhythmia from the patients automatically. To overcome the difficulties on real-time processing, we used four variavles; heart rate, QS width, morpholigy and axis. Templete generation routine was designed to produce patient's individual normal ECG pattern and store in the computer. The most important point of automatic detection is to discriminate the Q and J point. It is done by linear phase differentiation, the point that five point gradient is within a minimum value of 6Hz curve gradient is defined as Q and J points. The morphology calculation is simplified by simple addition and substraction, making real-time processing by modified cross correlation method. We find that both value of morphology and QS width will be used as a parameter of datermining the abnormalities of ECG signal automatically.

"Dual LAD" was defined as the early bifurcation of the proximal LAD into two vessels : a short LAD which remained in the anterior interventricular sulcus and does not reach the apex, and a long LAD which leaves the anterior interventricular sulcus only to return to the distal sulcus and continue to the apex. Recognition of "Dual LAD" is essential to prevent errors of interpretation of the coronary arteriogram and for planning of optimal surgical therapy. We report 2 cases of "Dual LAD" with the review of the literatures.

Supravalvular aortic stenosis may be defined as an obstructive congenital deformity of the ascending aorta which originates just distal to the level of the origins of the coronary arteries. It may be localized or diffuse, and includes a wide spectrum of pathologic changes. A 16 years old school boy was admitted because of exertional dyspnea for 6 years. Clinical diagnosis of supravalvular and valvular aortic stenosis with bicuspid aortic valves and myocardial hypertrophy was made by echocardiography and angiocardiography. Surgical correction was performed successfully. We presented a case of supravalvular and valvular aortic stenosis with a review of literatures.

6.Differentiation of Heterosexually Transplanted Embryonic Ovary Associated with Embryonic Testes of the Albino Rat into Castrated Hosts.
Yonsei Medical Journal 1965;6(1):1-6
The authors studied Witschi's theory of "corticomedullary inductors" with the; heterosexual grafts of the embryonal gonads of the rats in very close proximity or in remote distance each other for the effect of the inductor substance and the possibility of the substance acting as blood-borne agent when multiple embryonal testes and one or two ovaries were separately grafted in distant sites in the mammalian level. The heterosexual grafts of the embryonal gonads aging 16 days old were performed as the methods Macintyre (1956) used. Additionally the author grafted one or two embryonal ovaries of the same age in the subcapsular site and multiple embryonal testes of the same age in the similar site of the opposite kidney of the same host and allowed to develop at the sites for 3 weeks. The explants removed from the host, were fixed in Bouin's fluid, embedded in paraffin, sectioned serially at 6mu, and stained with hematoxylin and eosin. The embryonal transplanted ovary with testis in close contact, was inhibited and depressed to the one side probably due to the more rapid growth and differentiation of the testis as compared with the ovary and contained a tubular structure (seminiferous-like tubule) in which the degenerating oocytes were found. The author presumed the testicular effect upon the mutual ovary as the activity of the diffused inductor substance derived from the testis. In the group, which more than 15 embryonal testes (maximally 25 testes were grafted) were transplanted in the subcapsular site and one or two ovaries in the opposite site of the kidney of the same host, the ovarian grafts, which were at a distant site from the multiple testicular grafts, showed inhibited growth and differentiation by the similar appearance of the transplanted embryonal ovary with testis in mutual contact. By this observation the author considered the inhibited growth and differentiation of the effect of blood-borne inductor substance derived from the multiple testicular grafts of the opposite site of the host kidney.

Bacterial endocarditis is a disease with protean manifestations whose presentation has recently changed greatly. Right-sided endocarditis associated with congenital heart lesions is now relatively less common. Patients with ventricular septal defect are at risk for right-sided endocarditis, but its incidence is low in children and adolescents. The organism is frequently a staphylococcus and the clinical course is dominated by septic pulmonary infarction and septicemia. We reported two cases of pulmonic vegetation and pulmonary infarction associated VSD with brief review of literature.

This study was done to determine the value of thallium-201 stress myocardial perfusion scanning for identifying disease in the individual coronary arteries. Segement analysis of rest and stress myocardial perfusion scanning was performed in 65 subjects who underwent coronary arteriography. Anterolateral wall detects had a sensitivity of 70%, a spectivity of 92%, and a predicitive accuracy of 93.3% for identifying left anterior descending(LAD) coronary artery disease(CAD). Anteroseptal wall defects had a sensitivy of 62.5%, a specificity of 80%, and a predictive accuracy of 83.3% for identifying LAD CAD. Septal wall defects had a sensitivity of 67.5%, a specificity of 92%, and a predictive accuracy of 94.4% for identifying LAD CAD. Inferior wall defects had a sensitivity of 65.4%, a specificity of 89.7%, and a predictive accuracy of 80.9% for identifying right CAD. Posterolateral wall defects had a identifying left circumflex CAD. Thus, although senmental analysis of stress myocardial perfusin scanning can identify LAD CAD with high sensitivity and specificity, only moderate sensitivity and specificity are achieved in identifying right CAD or left circumflex CAD. But stress myocardial perfusion scanning has tendency to identify the most severely ischemic area, use of segmental analysis may be of benefit in the evaluation of patients with ischemic heart disease before or after coronary artery bypass graft and percutaneous transluminal coronary angioplasty.

To evaluate the diagnostic value of thallium-201 stress myocardial scintigraphic imaging and stress electrocardiography, sensitity, specificity and predicitive value of thallium-201 stress myocardial scintigraphic imaging were compared to simultaneously recorded 12 lead electrocardiography in 17 normal subjects and 30 patients with coronary artery disease who proved by coronary arteriography. The following results were obtained. 1) The mean age was 49.5+/-10.7 years(mean+/-SD)in subjects with normal coronary arteries and 53.1+/-8.8 years in patients with stenotic coronary arteries. 2) Fourteen patients had one-vessel disease, 10 two-vessel disease and 6 three-vessel disease. 3) Sensitivity of thallium myocardial scintigraphic imaging was higher than that of stress electrocardiography(86.7% vs 76.7%). 4) Specificity of both tests was same(70.6% vs 70.6%). 5) Sensitivity of thllium-201 stress myocardial scintigraphic imaging and stress electrocardigraphy in relation to the extent of coronary artery disease showed 78.6% vs 64.3% in one vessel disease, 90% vs 80% in two-vessel disease and 100% vs 100% in three-vessel disease. 6) Predictive value of thallium-201 stress myocardial scintigraphic imaging and stress electrocardiography revealed 83.9% vs 82% in the postive test and 75% vs 63.2% in the negative test. In conclusion, even though thallium-201 stress myocardial scintigraphic imaging was superior to stress electrocardiography in diagnosing coronary artery disease, scintigraphic defects were noted in 5 subjects with normal coronary arteries which could mislead to erroneous diagnosis of coronary artery disease. This point should be taken into consideration in the interpretation of thallium-201 stress myocardial scintigraphic imaging.
