title: [A comparative study of the two-dimensional echocardiography, ECG and selective coronary arteriography in detecting coronary artery disease].
abstract: This study was designed to compare the two-dimensional echocardiography (2 DE), electrocardiography (ECG) with selective coronary arteriography in 68 patients with chest pain for the evaluation of coronary artery disease. The sensitivity of 2 DE and ECG was 86.7% and 63.2%, P greater than 0.05. The specificity of 2 DE and ECG was 76.7% and 63.3%, P greater than 0.05. In patients with coronary artery stenosis greater than 50% of the diameter, the sensitivity was relatively 93.9% and 69.7%. In patients with stenosis greater than 75% of the lumen, that was 100% and 80%. In patients with old myocardial infarction, both of the sensitivity was 100%.
