: There is currently no method that can be used for a precise evaluation of pacemaker leads using X-ray images, which could be a valuable add-on in the follow-up of patients. The aim of this paper was to create a simple method to measure selected points and lines using the chest radiography of patients with cardiac pacemakers. : The study included 99 patients after permanent pacemaker implantation (72.0 ± 12.9 y; 58 W). The newly created method was used to evaluate the course of the leads based on an X-ray of the chest in an AP (posterior-anterior) projection (standing up) with optimization. The chest X-ray was applied to the original measurement grid, which was determined by specific anatomical points. For the purpose of this paper, a number of measurable parameters have been proposed. : The technical quality of the images was very good (4.50 ± 0.72). There were no gender-specific differences: women 4.46 ± 0.75/men 4.56 ± 0.67; = 0.5183. The quality of the imaging of the leads was also good (3.72 ± 0.83), and no statistical differences were found between the genders. After verifying the technical quality of the X-ray images, the tract of the leads was measured. The only significant difference was found in parameter E-this value describing the so-called "death bend", which was significantly lower in women (3.98 ± 1.35) vs. men (4.58 ± 1.49): = 0.039. : The presented method permitted the leads of a cardiac pacemaker to be precisely described with good clinical validity using chest radiography.
目前，尚无方法可以使用 X 射线图像对起搏器导线进行精确评估，这在患者随访中可能是一项有价值的附加内容。本文的目的是创建一种使用心脏起搏器患者的胸部 X 射线测量选定点和线的简单方法。
该研究纳入了 99 例永久性起搏器植入后的患者（72.0 ± 12.9 岁；58 例女性）。使用新创建的方法，根据胸部前后位（站立位）X 射线图像对导线的走行进行优化评估。将胸部 X 射线应用于原始测量网格，该网格由特定解剖学点确定。本文提出了一些可测量的参数。
图像的技术质量非常好（4.50 ± 0.72）。性别之间无差异：女性 4.46 ± 0.75/男性 4.56 ± 0.67； = 0.5183。导线的成像质量也很好（3.72 ± 0.83），性别之间无统计学差异。在验证 X 射线图像的技术质量后，测量了导线的走行。唯一有显著差异的参数是 E-该参数描述了所谓的“死亡弯”，女性的 E 值明显低于男性（3.98 ± 1.35） vs. 男性（4.58 ± 1.49）： = 0.039。
本文提出的方法使用胸部 X 射线可以很好地评估心脏起搏器导线的临床有效性。
