Example 1: Male, 70 years old. Due to sudden dizziness, palpitations, with limited physical activity on the right side, that day hospital treatment. Diagnosis of cerebral embolism, give dehydration, blood circulation and other treatment. 7 days after the symptoms slightly reduced into our hospital. Past history of coronary heart disease with atrial fibrillation for more than 20 years, heart rate 40 ~ 50 beats / min; Hypertension 20 years in recent years, blood pressure stabilized at 16 / 10KPa; Diabetes 2 years. Adhere to serve the United States and medicine. Blood glucose control at 7.8mmol / L. Physical examination: blood pressure 16 / 10KPa, heart rate 54 beats / min, palpable pleural apex apical beating, the heart to the left to expand, the heart rhythm is absolutely missing, apex area systolic and high tone diastolic Kazakh gas-like murmur. Capillary beating sign (+). The language is not clear. The right nasolabial groove slightly lighter. Lower right limb muscle tone, tendon knee reflex decreased. Muscle strength 4.5. Right lower body acuity touch decreased, pyramidal tract signs (a), I no special. 24 hours dynamic ECG showed chronic atrial fibrillation, Ⅱ ° AVB, ST segment partial down 0.1mv; echocardiography showed coronary heart disease, aortic valve calcification, valve reflex spectrum. Head CT scan to see the left occipital lobe 6.5cm × 3.2cm increase in size and density, kidney-like shape, surrounded by low-density around. Left temporal lobe is 2cm × 2cm size of high-density area, around the visible low-density circumflex. The posterior branch of the left basal ganglia area has a low density of about 0.5cm size, the left triangle and occipital horn shows unclear,
