[2] [3] LAAO does not completely eliminate the risk of stroke in patients with AF but it does reduce the risk of stroke from emboli that originate in the left atrial appendage. [4] The left atrial appendage can be purposefully occluded (i.e. closed) to help prevent the formation of clots in one of two ways. The Lariat procedure is a surgical ...
Configurations of elements 109 and above are not available. Predictions from reliable sources have been used for these elements. Grayed out electron numbers indicate subshells filled to their maximum. Bracketed noble gas symbols on the left represent inner configurations that are the same in each period. Written out, these are: He, 2, helium : 1s 2

Here [Ne] refers to the core electrons which are the same as for the element neon (Ne), the last noble gas before phosphorus in the periodic table. The valence electrons (here 3s 2 3p 3) are written explicitly for all atoms. Electron configurations of elements beyond hassium (element 108) have never been measured; predictions are used below.
This form of periodic table is congruent with the order in which electron shells are ideally filled according to the Madelung rule, as shown in the accompanying sequence in the left margin (read from top to bottom, left to right). The experimentally determined ground-state electron configurations of the elements differ from the configurations ...
This form of periodic table is more congruent with the order in which electron shells are filled, as shown in the accompanying sequence (read from top to bottom, left to right). The placement of helium (a noble gas) above beryllium (an alkaline earth metal) ordinarily attracts strong criticism from chemists.
Bachmann's bundle receives its blood supply from the sinoatrial nodal artery (right, left or both). [4]Besides Bachmann's bundle, the other three conduction tracts that constitute the atrial conduction system are known as the anterior, middle, and posterior tracts, which run from the sinoatrial node to the atrioventricular node, converging in the region near the coronary sinus.
