17个新的标准添加到简化版的Selvester QRS评分系统，包括完整的版本进行了评价，以确定其价值估计单梗死的大小。这些非Q波的标准可能是特别有用的关于后外侧梗死分布的左回旋支动脉。研究人群由21例前壁、30例下壁和20例后外侧单发心肌梗死（MI）患者组成，在最终稳定心电图上无束支分支或束支传导阻滞、心室肥大或既往MI的证据。完整系统的最大32个点能够指示96%的左心室中的MI，并且其估计的平均心电图MI尺寸与所有MI位置中的简化版本相比更好地近似解剖尺寸。后外侧MI组中，使用完整系统的解剖学和心电图MI尺寸之间的相关性更好，具有统计学显著性（简化r = 0.55，p <0.01 vs完整r = 0.70，p <0.0006）。V1中Q和S振幅≤0.3 mV和V2中Q和S振幅≤0.4 mV等标准特别有用。本研究记录了17个额外的非Q波标准提供的改进能力，这些标准已添加到该评分系统的完整版本中，涉及左回旋支动脉供血的左心室区域的梗死尺寸。
Seventeen new criteria added to the simplified version of the Selvester QRS scoring system to comprise the complete version were evaluated to determine their value in estimating the size of single infarcts. These non-Q-wave criteria might be particularly useful regarding posterolateral infarcts in the distribution of the left circumflex artery. The study population was made up of 21 anterior, 30 inferior and 20 posterolateral single myocardial infarction (MI) patients with no evidences of bundle branch or fasccular blocks, ventricular hypertrophy or previous MI on their final stable electrocardiogram. The complete system's maximum 32 points is capable of indicating MI in 96% of the left ventricle and it estimated a mean electrocardiographic MI size that better approximated the anatomic size compared with the simplified version in all Ml locations. The correlation between anatomic and electrocardiographic MI size using the complete system was better and statistically significant for the posterolateral MI group (simplified r = 0.55, p <0.01 vs complete r = 0.70, p <0.0006). Criteria such as Q and S amplitude ≤0.3 mV in V1and ≤0.4 mV in V2were particularly helpful. This study documents the improved ability provided by the 17 additional non-Q-wave criteria which have been added in the complete version of this scoring system regarding the sizing of infarcts in the region of the left ventricle supplied by the left circumflex artery.
