The Usefulness of HyperQ Recordings for the Early Diagnosis of Acute Coronary Syndrome in Patients Presenting With Chest Pain
The Usefulness of HyperQ Recordings for the Early Diagnosis of Acute Coronary Syndrome in Patients Presenting With Chest Pain

The purpose of the study is to assess the usefulness of high Frequency mid-QRS analysis in identifying the ischemic origin of patients presenting to the Emergency Room (ER)with Chest pain.

Introduction:

Chest pain is the leading cause of urgent admission to the Emergency Department (ED) in western countries.Acute Coronary Syndrome(ACS) continues to be among the most difficult to predict or diagnose. Misdiagnoses may lead to discharge of patients with ACS, who should have been admitted as well as costly unnecessary hospitalizations of patients who do not have ACS.

Objectives:

To evaluate the usefulness of High Frequency mid-QRS analysis in identifying the ischemic patients out of all patients presenting to the Emergency Room (ER) with chest pain.

Comparisons:

A continuous High Frequency Mid-QRS recording will be performed using the HyperQ System (BSP Ltd.) and compared to clinical, electrophysiologic and laboratory results. The golden standards used to compare the methods will be either CT-Angio, Echocardiography or Cardiac SPECT. A follow-up inquiry will be performed after 3 months and Coronary Angiography results will be sought and compared as well.
