ECG localization of myocardial infarction / ischemia and coronary artery occlusion (culprit)

ECG localization of myocardial infarction / ischemia and coronary artery occlusion (culprit)

Using the ECG to localize myocardial infarction / infarction and determine the occluded coronary artery It is often important to be able to determine the localization of  myocardial infarction  and ischemia, as well as being able to determine which coronary artery that is iccluded, and where the occlusion may be located. As discussed below, this may facilitate diagnosis of ischemia and infarction, and it may also guide management. For example, administering nitroglycerin (to alleviate ischemic  chest pain ) may cause hemodynamic collapse in patients with right ventricular ischemia/infarction; therefore, it is crucial to recognize  ECG  signs of right ventricular ischemia/infarction. Most clinicians will benefit from this knowledge. For cardiologists – particularly interventional cardiologists – this knowledge is of paramount importance as they must be able to directly pinpoint where the coronary artery occlusion is located (it affects the selection of coronary catheter). The term  culprit  – w…
