WebThe formal threshold for left anterior fascicular block (LAFB) is −45° not −30°, the latter being the cutoff for left axis deviation. LAFB, by itself, may widen the QRS slightly but usually not beyond 0.11–012 sec. Most cases of pure LAFB are associated with small r waves in the inferior leads and a small q wave in lead aVL. WebBlockages in the arteries that supply blood to your heart muscle are what cause most heart attacks. Usually, the blockage happens because plaque, a fatty, waxy buildup accumulates on the inside of your arteries. A blood clot can form on the plaque deposits, rapidly closing the artery and interrupting blood flow to the heart muscle.
