前壁急性心肌梗死V_1和V_(3R)导联ST段变化与冠状动脉分布的关系

目的：探讨前壁急性心肌梗死病人Ｖ１和Ｖ３Ｒ导联ＳＴ段变化与冠状动脉分布的关系。方法：前壁急性心肌梗死病人３４例，入院时均采集标准１２导联及Ｖ３Ｒ导联心电图，入院１０天内进行冠状动脉造影，评价心电图变化与冠状动脉分布的关系。根据Ｖ１导联ＳＴ段抬高幅度将病人分为两组：Ａ组（ＳＴ段抬高≥１．５ｍｍ，１５例）和Ｂ组（ＳＴ段抬高＜１．５ｍｍ，１９例）。将起源于右冠状动脉的圆锥动脉分为两种类型：小圆锥支型和大圆锥支型。结果：Ｖ３Ｒ导联ＳＴ段抬高在Ａ组和Ｂ组分别为１４例（９３％）和６例（３２％，Ｐ＜０．００１），小圆锥支型者在Ａ组和Ｂ组分别为１２例（８０％）和３例（１５％，Ｐ＜０．００１），大圆锥支型者１３例，均来自Ｂ组。结论：前壁急性心肌梗死病人入院时Ｖ１导联ＳＴ段抬高与Ｖ３Ｒ导联ＳＴ段抬高密切相关，均为小圆锥支型者。前壁急性心肌梗死Ｖ１导联无ＳＴ段抬高，表明除左前降支的间隔支供血外，心室间隔还得到大圆锥支型的血液供应而受到保护。

Feature Modeling and Variability Modeling Syntactic Notation Comparison and Mapping

Feature Model (FM) became an important role in Software Product Line Engineering (SPLE) field. Many approaches have been introduced since the original FM came up with Feature Oriented Domain Analysis (FODA) introduced by Kang in 1990. The main purpose of FM is used for commonality and variability analysis in domain engineering, to optimize the reusable aspect of software features or components. Cardinality-based Feature Model (CBFM) is one extension of original FM, which integrates several notations of other extensions. In CBFM, feature model defined as hierarchy of feature, with each of feature has a cardinality. The other notation to express variability within SPLE is Orthogonal Variability Model (OVM). At the other hand, OMG as standard organization makes an effort to build standard generic language to express the commonality and variability in SPL field, by initiate Common Variability Language (CVL). This paper reports the comparison and mapping of FODA, CBFM and OVM to CVL where need to be explored first to define meta model mapping of these several approaches. Furthermore, the comparison and mapping of those approaches are discussed in term of R3ST (read as “REST”) software feature model as the case study.
