简要总结
This will be a registry study that will enroll patients referred for an ECG treadmill test with nuclear myocardial perfusion imaging (MPI). The high frequency QRS (HFQRS) information will be recorded and analyzed automatically and simultaneous with the standard ECG signals by the HyperQ System. Results of subsequent tests performed on each patient will be collected and used to enhance the reliability of designating each patient as a CAD-negative (i.e., no significant coronary artery disease) or a CAD-positive (i.e., significant coronary artery disease).

CAD status
时间窗: one month follow up
The main goal of this registry will be to compare sensitivity, specificity, positive and negative predictive values of the HyperQ HFQRS analysis for detecting the presence of coronary artery disease to that of standard ECG analysis.
