Assessment of HyperQ Signal for Detecting Ischemia During Dobutamine Stress ECG

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.
Verified February 2007 by BSP Biological Signal Processing Ltd..
Recruitment status was:  Recruiting
Information provided by:
BSP Biological Signal Processing Ltd. Identifier:
First received: April 2, 2006
Last updated: February 28, 2007
Last verified: February 2007
The purpose of the study is to verify the ability of the HyperQ signal to detect Dobutamine induced Ischemia. The gold standard for ischemia will be the results of Angiography if performed, or Echocardiographic imaging, which was performed during the test.

Condition Intervention Phase
Myocardial Ischemia Device: HyperQ Signal recording Phase 3

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment

Further study details as provided by BSP Biological Signal Processing Ltd.:

Primary Outcome Measures:
  • HyperQ Signal recorded during the DES Test

Secondary Outcome Measures:
  • DES Outcome/ Angiography

Estimated Enrollment: 150
Study Start Date: March 2006
Estimated Study Completion Date: February 2007
Detailed Description:

Subjects referred for Dobutamine Stress Echocardiography who will sign an Informed consent form will go through the test. High resolution ECG from 12 leads will be recorded using BSP's HyperQ system before, during and following the Echo testing. This wil be done without interfering or affecting any aspect of the normal procedure. Standard Protocol will be used with standard test termination indications.

The Diagnostic stage will include analysis of the hyperQ signal, aiming to classify results as ischemic or non-ischemic.

The HyperQ data will be compared to DSE results which will be used as the "gold standard" for this study unless Angiography results are obtained.

An additional comparison evaluation will be performed to assess the advantage of the HyperQ results on the ST-changes results obtained from conventional ECG.In addition all recruited subjects will be followed for up to 12 months.During this period a phone call will be performed every 3 months to evaluate cardiac status, hospitalization and especially Angiography procedures.
