1. Infarction of the anterior wall of the left ventricle is always associated with occlusion of the left coronary artery. Infarction of the posterior wall of the left ventricle, in the absence of anomalies, is almost always associated with occlusion of the right coronary artery.2. When the infarction involves the anterior wall, the elevation of the R-T segment of the electrocardiogram is in leads I and II, and conversely when in the posterior wall, the elevation of the R-T segment is in leads II and III.3. Knowing the rôe of the right coronary artery in the supply of the posterior wall of the left ventricle, when we encounter a case of coronary occlusion in which the electrocardiogram shows R-T elevation in leads II and III, we can say with reasonable certainty that the occlusion is in the right coronary artery provided there is no anomaly of that artery.4. It has been demonstrated that the site of infarction and artery occluded can be accurately located during life. |
