Abstract

Objective: Right ventricular (RV) overload findings affect the risk classification and treatment approach in acute pulmonary embolism (APE). Recently, it was reported that a new electrocardiography (ECG) parameter, terminal D1S + D3R (T-D1S + D3R) pattern, supported the diagnosis of APE. We aim to search the relationship between T-D1S + D3R pattern and right ventricular dilatation (RVD) in APE.

Methods: This single-centre, retrospective study was designed with patients aged > 18 years. We screened 267 patients who underwent transthoracic echocardiography (TTE) because of confirmed APE in our emergency department. This study included 72 patients with RVD and 139 patients without RVD [male 41.7%, median age 73,0 (20.8) years; 49.6% male, median age 64,0 (24.0) years]. We compared T-D1S + D3R between RVD (+) and RVD (-) groups.

Results: We determined that RVD (+) group had more patients with the T-D1S + D3R parameter than RVD (-) group [51 (70.8%) vs. 25 (18.0%), p < 0.001]. In the univariate logistic regression analyses S1Q3T3, (in)complete right bundle branch block (RBBB), T-D1S + D3R, D3-V1 T wave inversion (TWI), V1-3/4 TWI, V1-3/4 ST-segment elevation, and frontal QRS-T [f(QRS-T)] angle predicted RVD, while T-D1S + D3R, V1-3/4 ST-segment elevation, and f(QRS-T) angle remained independent predictors of RVD in patients with APE.

Conclusions: T-D1S + D3R, a new ECG parameter, was an independent predictor of RVD in patients with APE.

一种新的心电参数终端 D1S + D3R 可预测急性肺栓塞的右心室扩张。

目的：右心室（RV）负荷过重的结果会影响急性肺栓塞（APE）的风险分类和治疗方法。最近有报道称，一种新的心电图（ECG）参数--末端 D1S + D3R（T-D1S + D3R）模式支持 APE 的诊断。我们旨在研究 T-D1S + D3R 模式与 APE 右心室扩张（RVD）之间的关系：这项单中心回顾性研究的对象是年龄大于 18 岁的患者。我们筛选了 267 名在急诊科确诊为 APE 而接受经胸超声心动图（TTE）检查的患者。这项研究包括 72 名 RVD 患者和 139 名无 RVD 患者[男性占 41.7%，中位年龄 73.0 (20.8) 岁；男性占 49.6%，中位年龄 64.0 (24.0) 岁]。我们对 RVD（+）组和 RVD（-）组的 T-D1S + D3R 进行了比较：结果：我们发现，RVD（+）组患者的 T-D1S + D3R 参数高于 RVD（-）组[51（70.8%） vs. 25（18.0%），P 结论：RVD（+）组患者的 T-D1S + D3R 参数高于 RVD（-）组]：T-D1S + D3R是一种新的心电图参数，是APE患者RVD的独立预测指标。
