Study of 6 peripheral channels of ECG in 62 children of the ages 9, 12, 14 showed that the heart frequency decreases with increasing age. In a same age, the frequency is higher in girl than in boy. Alpha angle valne decreases with increasing age. The electrocardiogram axis trends to move from right to left side, in contrary with the clock hand movement. Average duration of wave depends on the heart frequency. The altitude of wave of these three age groups has not significant difference

Introducing some advantages of cardiac ultrasound (through chest wall and trans-esophagus) in diagnosis of mitral stenosis. In Vietnam, Some kinds of cardiac ultrasound were applied since 1973 including M-mode ultrasound, 2D ultrasound, Doppler, and color ultrasound. Internal treatment and surgical treatment (including in closed or opened cardiac surgery, percutaneous mitral balloon valvotomy) are very efficient

The study was carried out on 50 patients with anthracosis treated from from 1stJanuary 2001 to November 31st 2001 at Thanh nhan hospital.anthracosis was the most frequent to be met among the whole occupational dust-related diseases. The patients have been got diseases, essentailly related to the long duration in contact with various dusts or by having histories that easy to be got diverse diseases of respiratory tract. The commonest symptoms in anthracosis are dyspnoea 70%, cough 62%, sputum excretion 40%, modifications or pulmonary and X-rays, eletrocardiogram, especially respiratory function deficiency. Diseases and complications frequently met of anthracosis were bronchitis, pneumonia, cardiac insufficiency, chronic cardiopulmonary diseases, cardio arrhythmia, pulmonary infarction and hemoptysis
