Time Perspective: Prospective
|Official Title:||Reproducibility of T Wave Alternans Testing in Patients With Ischemic Heart Disease.|
- Reproducibility of TWA test results [ Time Frame: 1 week ] [ Designated as safety issue: No ]
- Ventricular arrhythmias during exercise [ Time Frame: 1 week ] [ Designated as safety issue: No ]
|Study Start Date:||May 2008|
|Estimated Study Completion Date:||May 2009|
|Estimated Primary Completion Date:||January 2009 (Final data collection date for primary outcome measure)|
The study will be performed in the Cardiac Rehabilitation Center at Assaf Harofeh Medical Center. Patients with coronary artery disease will be eligible to enroll.
Patient will undergo an exercise test on a stationary bicycle. TWA will be measured at heart rate of 105 and 115 BPM. The test will be repeated one week later in the same fashion. The patient will continue follow-up in the rehabilitation center as dictated by the rehabilitation program. Patients will be kept on their regular medications and there will be no change of the medications from the first TWA measurement to the second.
