I would be concerned about underlying coronary artery disease in the following situations: Atrial flutter with rate-related ST depression: Thanks to Christopher Watford of EMS 12-lead.com for spotting this one! ALCAPA is present at birth … These electrodes detect the small electrical changes that are a consequence of cardiac muscle depolarization followed by repolarization during each cardiac cycle (heartbeat). Normal Anatomy of the Coronary Artery System The four main coronary arteries evaluated at CT are the right coronary artery (RCA), the left main coronary artery (LCA), the left anterior descend-ing (LAD) artery, and the left circumflex (LCx) artery. Your heart is a strong muscular pump that is responsible for moving about 3,000 gallons of blood through your body every day. Localization of myocardial infarction / ischemia is done by using ECG changes to determine the affected area and subsequently the occluded coronary artery (culprit). Normal Anatomy of the Coronary Artery System. Jong G, Ma T, Chou P, et al. Many ischemic ECG patterns are found in patients with acute left main coronary artery occlusion. highly informative blog posts on LMCA occlusion, Electrocardiography in Emergency, Acute, and Critical Care, Critical Decisions in Emergency and Acute Care Electrocardiography, Chou’s Electrocardiography in Clinical Practice: Adult and Pediatric, Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International License, Left main coronary artery (LMCA) stenosis, Proximal left anterior descending artery (LAD) stenosis, Lead aVR is electrically opposite to the left-sided leads I, II, aVL and V4-6. However, this patient actually had severe multi-vessel disease. Anomalous origin of the left or right coronary artery from the pulmonary artery is a rare and hemodynamically significant coronary anomaly seen in 1 of 300000 live births and accounts for 0.25–0.5% of all congenital heart defects [1,2,3].The anomaly was first discovered during an autopsy in 1865 [] and was later described as a clinical syndrome (known as Bland … 2006 Oct;39(4 Suppl):S68-72. STE in aVR ≥ 0.5 mm was also an independent predictor of mortality (in-hospital mortality was 19% in those with ≥ 0.5 mm STE in aVR compared to only 5% in those without). Infarction in this area could theoretically produce ST elevation in aVR, STE in aVR ≥ 1mm indicates proximal LAD / LMCA stenosis or severe 3VD, STE in aVR ≥ 1mm predicts the need for CABG, Absence of ST elevation in aVR almost entirely excludes a significant LMCA lesion, STE in aVR ≥ 1mm is highly specific for LAD occlusion proximal to the first septal branch, STE of ≥ 1mm in aVR during exercise stress testing predicts LMCA or ostial LAD stenosis, STE in aVR ≥ 0.5mm was associated with a 4-fold increase in mortality, STE in aVR ≥ 1mm was associated with a 6- to 7-fold increase in mortality, STE in aVR ≥ 1.5mm has been associated with mortalities ranging from 20-75%, STE in aVR (≥ 0.5mm) occurred with a significantly higher incidence in the LMCA group (88%) than in the LAD (43%) or RCA (8%) groups, Magnitude of STE in aVR was significantly greater in the LMCA group (1.6 ± 1.3 mm) than the LAD group (0.4 ± 1.0 mm), STE in aVR ≥ V1 distinguished the LMCA group from the LAD group with 81% sensitivity, 80% specificity and 81% accuracy, Two-thirds of patients with STE in aVR ≥ 1 mm had either LMCA stenosis or severe 3VD, Degree of STE in aVR was an independent predictor of mortality: STE of ≥ 1 mm was associated with a six- to seven-fold increase in in-hospital mortality (odds ratio of death = 6.6), Magnitude of STE in aVR was also closely associated with rates of recurrent ischemic events and heart failure, STE in aVR predicted the need for CABG – coronary grafting was required in 22% of patients with aVR STE > 1mm compared to 5% of those without, STE in aVR ≥ 0.5 mm was the strongest predictor of LMCA or 3VD (78% sensitivity, 86% specificity, 57% PPV and 95% NPV), STE in aVR was superior to the presence of ST depression in other leads for predicting LMCA/3VD. 2008 Mar;28(3):376-92 [, Rostoff P, Piwowarska W, Konduracka E, Libionka A, Bobrowska- Juszczuk M, Stopyra K, et al.
