Diagnostic value of R-wave amplitude increase during treadmill exercise testing for detecting coronary artery disease.

R wave amplitude during exercise. Relation to left ventricular function and coronary artery disease.

Change in R wave amplitude (mean delta R) was measured sequentially during and after 12 lead maximal treadmill exercise tests in 14 subjects with normal coronary arteries and 62 patients with coronary artery disease. In normal subjects mean delta R decreased maximally one minute after exercise and returned to control levels within three minutes. In contrast, mean delta R increased in patients w...

Treadmill exercise test using body surface mapping. A quantitative diagnostic method for coronary artery disease.

In order to evaluate coronary artery disease quantitatively we recorded body surface maps before and after treadmill exercise in 27 patients suspected of having coronary artery disease. Electrocardiograms were recorded from 87 points on the anterior and posterior chest wall. The pre-exercise ST level was subtracted from post-exercise ST level at each lead point and an ST difference MAP was cons...

Diagnostic Accuracy of Gated-SPECT Myocardial Perfusion Imaging and Exercise Stress Test for Diagnosis of Coronary Artery Disease

Background and Objective:Accurate diagnosis of CAD using noninvasive procedures is of great importance. The aim of the study is to assess diagnostic accuracy of myocardial perfusion imaging and compare it with exercise stress test in order to decipher a more accurate and cost-effective method for CAD detection. Materials and Methods:Of 430 consecutive patients suspected with CAD, 104 performed...

Reliable prediction of coronary disease using treadmill exercise testing.

Exercise Treadmill Test in Detecting Asymptomatic Coronary Artery Disease in Type 2 Diabetes Mellitus

BACKGROUND The present study was designed to develop criteria for screening patients with type 2 diabetes mellitus (T2DM) for asymptomatic coronary artery disease (CAD). METHODS A total of 213 patients with T2DM without typical angina or chest pain were studied between 2002 and 2007. We also evaluated 53 patients with T2DM who had reported chest discomfort using an exercise treadmill test (ET...
