Brief Summary:
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.

Outcome Measures

Primary Outcome Measures :
  1. 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.
