The lead facing the injury vector head shows ST-segment elevation and the lead facing the vector tail (opposite leads) shows ST An electrocardiogram — abbreviated as EKG or ECG — is a test that measures the electrical activity of the heartbeat. With each beat, an electrical impulse (or “wave”) travels through the heart. This wave causes the muscle to squeeze and pump blood from the heart. A normal heartbeat on ECG will show the timing of the top and lower chambers. There may be subtle (or overt) signs of an inferior or lateral MI— look for ST elevation in other vascular territories. If the anterior leads represent a mirror image of the posterior wall, then the ECG turned upside-down reveals that the tall anterior R-waves become deep posterior Q-waves, the ST-depression becomes ST-elevation, and upright T-wave becomes terminal T-wave inversion. The "LCX", or left circumflex artery (or circumflex artery, or circumflex branch of the left coronary artery) is an artery of the heart It passes at first behind the pulmonary artery and then comes forward between that vessel and the left atrium to reach the anterior interventricular sulcus, along which it descends to the notch of cardiac apex.

ECG reflects the physiology Patients with ST elevation in one territory often have ST depression in other 7 Feb 2018 Welcome to this edition of ECG Pointers, an emDOCs series designed to an inferior or lateral MI— look for ST elevation in other vascular territories. where he was found to have severe multi-vessel coronary artery di 15 Feb 2016 Here is an excellent case of STEMI in more than one territory due to LMCA Here is an ECG of a patient who was found to have triple-vessel Keywords: Infarct related artery; Culprit vessel; Acute coronary syndrome; This is a review of features in ECG to diagnose the culprit artery responsible for the When present on an ECG*, what does coronary artery disease look 3. Which vessel is involved? B. Is experiencing myocardial ischemia in the RCA territory. The localization of culprit vessel territory on ECG broadly correlated with RWMA on 2D-Echo. Echo could elaborate the territory of infarction in greater detail than perfusion defect which is characteristic of ischemia affecting the LAD territory.

The present study has been undertaken to observe patterns of ECG changes in a patient with acute ST-elevation myocardial infarction (STEMI) and correlating these changes with coronary angiography for identifying the culprit, infarct-related artery. In this ECG, posterior MI is suggested by the presence of: ST depression in V2-3. Tall, broad R waves (> 30ms) in V2-3. Dominant R wave (R/S ratio > 1) in V2. Upright terminal portions of the T waves in V2-3 .

C. Has a new occlusion of the LAD. (ST elevation, no Q waves) 4 Territories S1 supplies the basal part of the interventricular septum, including the bundle branches (corresponding to leads aVR and V1) D1 supplies the high lateral region of the heart (leads I and aVL) Occlusion proximal to S1 The ECG criteria for a posterior myocardial infarction (MI) are discussed including the R:S ratio and the association with an inferior MI. A posterior ECG is discussed with leads V7, V8 and V9. Sometimes, the ECG can show that the heart is enlarged (usually due to high blood pressure) or that the heart is not receiving enough oxygen due to a blockage in one of the blood vessels that supply the heart (the coronary arteries). ECG localisation The electrocardiogram (ECG) is a key investigation in diagnosing acute ST-segment elevation myocardial infarction (STEMI). During acute transmural ischaemia, one of the important determinants of the site of coronary artery occlusion is the direction of the vector of ST-segment deviation. The injury vector is always oriented toward the injured area. The lead facing the injury vector head shows ST-segment elevation and the lead facing the vector tail (opposite leads) shows ST An electrocardiogram — abbreviated as EKG or ECG — is a test that measures the electrical activity of the heartbeat. With each beat, an electrical impulse (or “wave”) travels through the heart. This wave causes the muscle to squeeze and pump blood from the heart.

In most cases this is picked up by the treadmill ECG usually done along with stress myocardial perfusion imaging.
