Background : The effective ventricular function during ejection and filling is likely to depend on the coordinated action of the longitudinally and circumfertially orientated myocardial fibers and the function of these longitudinal fibers has not been extensively studied. Methods : The role of longitudinally and circumferentially orientated fibers in left ventricular wall motion was evauated by M-mode echocardiograms of the mitral ring(whose motion reflect long axis change) and the standard minor axis(left ventricular posterior wall), simultaneous recordings of phonocardiograms and electrocardiograms on the paper(speed 100mm/sec), in 17 patients with mitral valvular replacement(MVR) and 24 normal controls. Results : In the controls long axes : 20 ± 3 msec, mean ± SEM) during early systole, indicating left ventricle become more spherical. This phase differences were not observed in the patients with mitral valvular heart disease before MVR. After MVR the onset of long axis shortening was more delayed during early systole than that of short axis (-19 ± 9 msec) and the end of shortening was also prolonged to early diastole compared with that of preoperation (33 ± 11 msec vs 84 ± 5 msec, mean ± SEM, p<0.01 by paired t-test). Conclusion : We observed the time relations between long and short axis motion in normal controls. It can be concluded that the reversed time relation between two axes after MVR is one of the important factors which may effect negatively on ventricular function and long-term prognosis, thus surgical procedures to preserve papillary annular continuity should be considered in patients with mitral valvular disease. Key wards : Mitral annulus motion, Mitral valve replacement, Echocardiography

It is known that the normal His-Purkinje system provides for nearly synchronous activation of the right and left ventricles. When this His-Purkinje conduction is abnormal, the resulting sequence of the both ventricular contraction should be changed. These abnormal mechanical consequences resulting from abnormal conduction system have been difficult to demonstrate because these are very rapid and complex. We evaluate the phase angle analysis using radionuclide gated blood pool scan(GBP) as a quantitative method which can determine the asynchronous contraction of left ventricule in patients with complete left bundle branch block(C-LBBB, 20 cases) and complete right bundle branch block(C-RBBB, 15 cases). The results as follows : 1) The ejection fractions, peak ejection rates, in GBP were significantly decraesed in patients with C-LBBB compared with controls(10 cases, 70± 4.2 vs 44± 13.9%, 3.51± 0.62 vs 2.48± 0.98, p<0.05 by t-test respectively). The peak filling rates were also decreased in patients with C-LBBB(3.38± 0.92 vs 1.76± 0.71, 1A.05). 2) In the phase angle analysis, the standard deviations and the width of half maximum of phase angle were significantly increased in patients with C-LBBB(8.6± 1.8 vs 20.6± 18.1, 16.0± 3.9 vs 22.5± 9.2, p<0.05 by t-test respectively). And the ranges of phase angle were also increased in C-LBBB(51.3± 5.4 vs 95.7± 31.7, p<0.05). 3) But there were no significant differences in GBP and phase angle analysis between patients with C-RBBB and controls. As the results above, it can be concluded that the phase angle analysis can provide an accurate noninvasive method to detect the asynchronous contraction in patients with abnormal intraventricular electrical activation.

On retrospective review of medical records of 420 patients with atrial fibrillation(AF), 59 cases(14%) experienced cerebra or peripheral embolisms(5 cases) in their medical history(13.5%), or at the time of first visit(56%) or during follow-up period after documented AF(31%). The underlying diseases of AF were valvular heart disease(55%), cardiomyopathy(13%), hypertension(6%), congestive heart failure, hyperthyroidism(3%), constrictive pericarditis, congenital heart disease(2%) and chronic obstructive lung disease(0.2%), 16% of these patients had no causative disease(long AF, 43 cases). There were no significant differences between incidence of embolism and age, sex, underlying disease, left artial size. The mean left artial anteroposterior diameter in M-mode echocardiography was larger in the group of patients with heart disease(n=221) than in those of lone AF(n=43) (52.5±11.0㎜ vs 4.7±7.9㎜, p<0.005) and the patients with heart disease were younger than those with lone AF(48.3±14.1 vs 61.6±10.5, p<0.005). In spite of these differences between two groups, the incidence of embolism didnot differ. All patients(13 cases) experienced a embolism after documented AF had underlying heart disease. It can be concluded that the incidence of thromboemlism is high in patients with AF and routine anticoagulants therpy will be needed, especially in the patients with heart disease.

회상요법이 치매노인의 인지기능과 기억 및 문제행동, ADL 증진에 미치는 영향
전은석,도종두 한국보건복지학회 2004 보건과 복지 Vol.7 No.-
Nowadays senile dementia is on the rise as consequence of serious social problem because of it is old aged society by improvement of medical service. However remedial approach is not being done because of we still don't have an infallible cure of dementia and dementia is been hard to cure. Thus it is introduced in this study to the concept of Reminiscence therapy, which is one of the remedies. I tried to find out which remedy is the best to cure demented elderly and which is been able to use on field. For this study, I applied a developed Reminiscence therapy program in actual practice. First, I chose nine demented elderly who are lived in 'Sunwoo Dementia Consulting Center' located in Daejon metropolitan city, and I separated them in two groups for this study. Second, I applied Reminiscence therapy to first group, and I did not apply any Reminiscence therapy to second group. The first group was applied the program, one time a week for fifty minutes, for about three months. The measurement of Cognitive function was practiced four times - one time before applying the Reminiscence therapy by HDS-R and ADAS-Cognitive, and one time during applying the program, and one time after ending of the program and one time after one month from ending the program. The measurement of Memory and Behavior problems function was practiced four times - one time before applying the Reminiscence therapy by MMSE, and one time during applying the program, and one time after ending of the program and one time after one month from ending the program. The measurement of ADL was practiced two times - one time before applying the Reminiscence therapy by the ADL, and one time after one month from ending the program. Effectiveness of Reminiscence therapy and possibility of application of Reminiscence therapy program are proved because of this study shows the Reminiscence therapy keeps well the Cognitive function, Memory and Behavior problems function and the ADL function of demented elderly, improves those functions, affects positively to the whole life. However we must develop Reminiscence therapy, which is proper to a trait of character, and expanded application is needed. In addition, temporary remedy must not be performed but continuous cure. This study will be complement by studying about special situation researcher cannot control something like unexpected death of demented elderly by other diseases.
