: Obesity is a major cause of repolarisation defects of the heart. The frontal QRS-T angle is a new parameter used for cardiac evaluation. This study aimed to evaluate the effects of a laparoscopic cholecystectomy and anaesthetic agents on the frontal QRS-T angle in individuals with obesity. : A total of 91 patients who underwent a laparoscopic cholecystectomy surgery were included in this study. The patients were divided into two groups according to body mass index (BMI) < 30 ( = 68) and ≥30 ( = 23). The frontal QRS-T angle (FQRST), QT interval (QT), corrected QT, and other electrocardiography (ECG) findings were recorded at different time points. In the BMI ≥ 30 group, the frontal QRS-T angle and QT interval measured during the intraoperative period were statistically higher than those of the BMI < 30 group ( < 0.001, < 0.001). Additionally, the frontal QRS-T angle value was statistically higher in all patients postoperatively compared with the preoperative and intraoperative periods ( < 0.001). Furthermore, there was a positive correlation between the BMI and the frontal QRS-T angle. Our study found that the QRS-T angle and the QT interval duration measured during surgery in the BMI ≥ 30 group who underwent a laparoscopic cholecystectomy were significantly higher than in the BMI < 30 group. : We recommend close haemodynamic monitoring during and after surgery for patients with obesity undergoing a laparoscopic cholecystectomy.
肥胖是心脏复极异常的主要原因。额面QRS-T角是用于心脏评估的一个新参数。本研究旨在评估腹腔镜胆囊切除术和麻醉药物对肥胖个体额面QRS-T角的影响。
本研究共纳入91例行腹腔镜胆囊切除术的患者。根据体重指数（BMI）将患者分为两组，BMI<30（n = 68）和BMI≥30（n = 23）。在不同时间点记录额面QRS-T角（FQRST）、QT间期、校正QT以及其他心电图（ECG）结果。在BMI≥30组中，术中测量的额面QRS-T角和QT间期在统计学上高于BMI<30组（P<0.001，P<0.001）。此外，与术前和术中相比，所有患者术后的额面QRS-T角值在统计学上更高（P<0.001）。而且，BMI与额面QRS-T角之间存在正相关。我们的研究发现，BMI≥30组行腹腔镜胆囊切除术患者术中测量的QRS-T角和QT间期持续时间显著高于BMI<30组。
我们建议对行腹腔镜胆囊切除术的肥胖患者在手术期间和术后进行密切的血流动力学监测。
