I need a 12 lead ECG course why does the American Heart Association calls the course STEMI ?
The Extended version of the ECG is more than an elaboration it is an important diagnostic tool that determines treatment, urgency and whether thrombolytics are indicated in a acute myocardial infarction. The term STEMI more accurately describes the depth and purpose of the test. 4%-5% of all people presenting to the emergency department or first encounter with emergency medical services are myocardial infarctions showing ST Elevations. Most Deaths from (STEMI) ST elevation MI occur in the first 2 hours. These people need to be transferred immediately to a healthcare facility that can manage PCI or Percutaneous Coronary Intervention.
There are several methods of determining if a person has suffered a heart attack.
One method is blood tests specifically elevated enzymes indicating heart damage may have occurred. Many Heart attacks are silent meaning there is no pain or discomfort to the person.
A Second Method the 12 lead ECG is diagnostic test that records electrical changes in the heart during the Cardiac Cycle. Abnormalities in the electrical conduction cycle during the cardiac cycle are often seen as changes or elevations between the S Wave and the T Wave. When this segment is elevated a treatable heart attack associated with a blockage. This Sentinels not only the general location of ishemia but also the likely coronary arteries involved and alerts the professional that a cardiac intervention is needed right away. Interventional Cardiology such Angioplasty at the heart center.
STEMI Stands For
ST ( the segment of the cardiac cycle effected)
E (stands for Elevation)
MI ( stands for Myocardial Infarction a medical term for a heart attack caused by a blockage of one or more coronary arteries )
