Actual (reported)Accurate detection of a heart attack (an acute myocardial infarction) is one of the most pressing needs in medicine. Recordings of the electrocardiogram (ECG) (electrical activity of the heart) are one of the first tools used to diagnose a heart attack, but the ECG is not very accurate, especially at the beginning of a heart attack. A new technique for analysing a special part of the ECG may provide more accurate detection of a heart attack. The study hypothesis is that this new technique, the HFQRS analysis, will provide important additional information to that available from the regular ECG.

Actual (reported)diagnosis or rule-out of acute coronary syndrome
The primary end-point of the study is definite discharge diagnosis or rule-out of acute coronary syndrome, based on cardiac biomarkers, ECG changes, clinical symptoms and cardiac imaging tests.
diagnosis or rule-out of ACS will be determined at two time points: 1) upon diacharge when discharge diagnosis is determined. Follow up information will be obtained one month post discharge
Patients presenting with chest pain to the Emergency Department, who are suspected of having ACS, will be asked to participate in the study.
