Case Reports[True posterior infarction diagnosis. Report of three cases].
Acute Coronary Syndrome with ST segment elevation requires rapid reperfusion, which is why the timely identification of these conditions, based on the patient's symptoms and the correct interpretation of the EKG, is essential for therapeutic decisions.
