Nehb lead ECG diagnosis of coronary heart disease (coronary angiography compared with 28 cases)
TNehb lead ECG can be seen reflected in almost normal cardiac insufficiency lead ECG 1 times. 2.31l6 two cases of ST-T 0 change in electrogram comparison results in Table 3. As can be seen from Table 3, D and A segment depression in leads sT rate variability is much higher than the V-lead; changes in the T wave, D,[link widoczny dla zalogowanych], and A Guide Medical Journal in 1994, Min Vol 6_ 29 Sri Lanka Table 3llB down two coronary heart lead PCCW hi comparison of ST-T changes associated Yang also higher than V. 2.4 Coronary angiography and two-lead ECG loop comparison conducted in our hospital is currently 33 cases of coronary angiography, 5 down because of the information base can not compare the excluded. Friends back in the mining, down male 26, female 2 guillotine, coronary angiography found that more than one or a narrow radius ≥ 75% coronary artery to coronary artery stenosis group were (19 guillotine), as amended,[link widoczny dla zalogowanych], the normal group (9 cases),[link widoczny dla zalogowanych], Two-lead ECG diagnosis of coronary Jue narrow results in Table 4. Table 4 Two ECG diagnosis of coronary artery stenosis compared Nehb lead ECG in 28 cases of patients with the highest CPC amidine contrast detection sT-T changes in 24 patients. Vein stenosis in which l8 fall away. F stenosis in 6 patients without ECG change the threshold a sT-T, 20 sides, which narrow crown amidine group of 15 patients. No stenosis in 5 cases. Nchb lead ECG sT-T change on the remote vein stenosis with a sensitivity of 94.7% t} 60% and specificity of conventional ECG sensitive to live for the 7119 cycle,[link widoczny dla zalogowanych], the specificity was 64.1. Two-lead ECG diagnosis of coronary heart disease was no significant difference in specificity (P> 0. 05), but Nehb lead ECG of the Min-Sheng Qi of higher than normal ECG (P <0.os). Discussion of the clinical ECG 3 offer permanent cardiac vector loop generated by two projectors. ECG into a three-dimensional graphics Tong cardiac vector loop in the formation of three planes projection plane vector, the so-called Some fell on a fixed axis. After this the Nehb lead ECG's have the same projection process twice, only projections of different plane and ECG, which is a three-dimensional ECG vector loop the right to vote in the soil the second threat to the sternum and the apex and apical heard the level of the three axillary line points on the inclined plane formed by the projection, the formation of plane vector, and then in parallel with the slant of light projection vector map in this slope, so the shadow falls on the blue point of the triangle formed by the edges which constitute the axis ECG generated ring】. Nehb lead ECG is close to the heart of the small triangle bipolar lead, and the belly of the small triangle near the center axis, thereby increasing the sensitivity of the lead, particularly lead D vector projection line through the more able significantly earlier to reflect myocardial ischemia and injury】. Our data suggest that, Nehb lead ECG in coronary insufficiency occurs when the ST-T changes in ECG than positive rate appears to change the level significantly. Thus we believe that, Nchb lead ECG, especially in D leads to the early diagnosis of coronary heart disease and practical value. So far, diagnostic coronary angiography is the most accurate square enamel, it can not only determine the site of coronary artery stenosis, and the bladder does Jue narrow indigo extent, but time-consuming operation. High-technology equipment to the palm, are expensive and require skilled technicians operate and therefore it is not yet universal. Coronary disease at the same time tracings of the selenium species lead ECG, electrocardiogram Nehb lead to explore the diagnostic value of coronary heart disease, the results showed: the highest out = amidine seedlings were caused by post-mortem diagnosis of coronary insufficiency 『 no significant difference in specificity. But the sensitivity was significantly higher than that of conventional ECG difficulties. But the park we choose a small number of cases the tiger, the existence of certain limitations, to be studied further exploration closure. However, we believe that the patient at the same time as the two lead ECG tracings and undecided in the comparative observation, Tony will help to assist with the conventional ECG is still difficult to diagnose coronary heart patients. The method is simple and solid non-invasive, and thus more easily accepted by patients, in clinical application.
