With the improvement of living standards, the incidence of coronary heart disease has increased annually. ECG in the diagnosis of coronary heart disease is important, coronary angiography (coronary angiography) coronary artery disease once was considered the gold standard for diagnosis. This paper conducted in patients with coronary heart disease ECG and coronary angiography, and the results are as follows. An object and method of 1.1 cases of Choice in January 1999-December 2000 hospitalized ECG and crown Pulse scan 118 cases of patients, according to 1979 WHO criteria for the diagnosis of coronary heart disease, of which 76 male and 42 female, aged 39 -72 years old, with an average age of 56.67 10.48 years. Observation 1.2 ECG : Conventional 12-lead ECG and exercise-test is very consistent with a myocardial ischemia can be judged as positive electrocardiogram. Coronary angiography : diagnostic method. Reduce coronary diameter ≥ 50%, the judgment was positive. 1.3 statistically using X2 test. 2 Results 2.1 electrocardiogram (ECG) and coronary angiography (CAG) of the results of 118 cases of coronary heart disease patients, Coronary angiography was 74 cases, 44 cases negative. Coronary angiography with contrast sensitivity of the electrocardiogram for 73.0% and a specificity of 79.5%. CAG 2.2 ECG findings and the positive rate of ECG with the two methods in the detection of coronary heart disease positive rate side face no significant difference. 3 to discuss the incidence of CHD is rising year on year. Diagnosis of Coronary Artery Disease attracting increasing attention. ECG diagnosis of coronary artery disease is a common one. Its economic, practical and suitable for wide clinical application. In general, coronary insufficiency, ECG can be shown as the positioning of a T ST dynamic change. However, hypertrophic cardiomyopathy, pulmonary infarction, and other diseases can also cause an electrocardiogram ST-T changes. Moreover, some patients had serious coronary stenosis, but normal resting electrocardiogram. The test results showed that the ECG of coronary heart disease had a sensitivity of 73.0% and specificity of 79.5%. The crown create positive group, 17 patients with negative, and 12 cases of coronary stenosis "70%, five cases ≥ 70%. The reason may be significant cardiac hypertrophy and heart disease -- such as myocardial ischemia hide the change; may also apparent heart failure patients, serious cardiac arrhythmia, unstable angina, and so on, should not exercise treadmill test OK, Resting in the circumstances, given the burden on small heart, ECG failed to show myocardial ischemic lesions. This has told us that normal ECG can not be easily excluded from coronary heart disease, the need analysis. Coronary angiography is a recent development for the diagnosis of coronary intervention. Because the prices more expensive and invasive for inspection, not extensive. The results show that it and ECG findings in the positive rate was not significantly different, but can directly reflect coronary lesions, for the next phase of guiding significance, and placed stents, coronary bypass and other treatment methods provided strong support. Therefore, coronary angiography worthy of further promotion. The results showed that the crown create negative group, 17 patients ECG positive. Had called coronary angiography for the diagnosis of coronary heart disease gold standard. However, the study found that coronary spasm, the coronary artery disease, hemoglobin and oxygen dissociation abnormal, Sympathetic hyperactivity, excessive secretion of catecholamine metabolism and myocardial abnormalities such circumstances, in patients with coronary artery disease coronary angiography can be no significant stenosis. The other hand, hypertrophic cardiomyopathy, left ventricular hypertrophy, and other diseases can also cause an electrocardiogram ST-T changes. The group made the highest negative and the positive performance of the ECG patients, three cases after the other diagnosis of hypertrophic cardiomyopathy, be beta-blockers and calcium antagonist treatment, the symptoms were relieved. See also other similar reports. ECG and coronary angiography in the diagnosis of coronary heart disease both ways. However, the diagnosis of coronary heart disease should be combined with clinical comprehensive analysis can not only rely on coronary angiography or ECG diagnosis or exclusion of coronary heart disease.
