Detection of Coronary Artery Disease Using Analysis of High Frequency QRS: The HyperQ Registry (HyperQ)

The recruitment status of this study is unknown. The completion date has passed and the status has not been verified in more than two years.

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).

Primary Outcome Measures:
  • CAD status [ Time Frame: 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.

Estimated Enrollment: 900
