简要总结
The aim of this study is to determine whether a new vectorcardiogram (VCG) analysis will facilitate the detection of significant coronary disease (CAD) in patients with normal rest 12-leads ECG (NE).
详细描述
Patients with NE will undergo coronary angiography for routine indications. Prior to the angiography a computerized simultaneous multi-leads ECG will be recorded and, using a new dedicated algorithm for 3D electrical activity reconstruction, the investigators will plot the horizontal VCG of the whole ECG cycle. Using this new VCG analysis we will determine whether the patients have normal coronary arteries or coronary disease.

主要结局
Detection of CAD in patients undergoing routine coronary angiography
时间窗: One month
Following angiography patients will be categorized as having normal coronary arteries (NC) or coronary disease (CD) if more than 50% lumen diameter narrowing is found in one of the arteries.
