The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details.
Information provided by (Responsible Party):
Loma Linda University
  Purpose
The purpose of this study is to measure T-Wave Alternans (TWA) in patients with acute coronary syndrome. Researchers are blinded to clinical TWA measurements. The investigators will then try to determine if T-Wave alternans correlates with clinical outcome of patients with Acute Coronary Syndrome. During routine care of the patient, the T Wave Alternans is measured.

Condition Intervention
Chest Pain Acute Coronary Syndrome Acute Myocardial Infarction Device: Observational Measurement of T-wave Alternans Device: T-wave Alternans

Primary Outcome Measures:
  • correlation of T-Wave Alternans with Acute myocardial Ischemia [ Time Frame: 6 month ]
    We hope to correlate the Twave Alternans with Acute Myocardial Ischemia. Most importantly we are trying to create a sensitive measure of acute myocardial Ischemia or a rule out study.

Groups/Cohorts Assigned Interventions
Chest Pain
Acute Myocardial ischemia
Device: Observational Measurement of T-wave Alternans
Measurement is similar to typical EKG
Device: T-wave Alternans
T-Wave Alternans will be measured in an observational fashion
