A Novel Method for Enhancement of Standard Rest Electrocardiograms (ECG) Provides New Parameters for Early Detection of Coronary Artery Disease (CAD)

• Conditions: Cardiovascular Diseases
• Interventions: Procedure: Routine coronary angiogram

• Registration Number: NCT01909817
• Lead Sponsor: Hillel Yaffe Medical Center

Brief Summary

The investigators aim to determine whether a new method of enhancing and improving ECG acquisition, analysis and display is effective. The investigators will perform superimposition and summation of multiple standard ECG cycles, in the same lead, by temporal alignment to the peak R wave and voltage alignment to an improved baseline at the T-P segment.
