ImportancePrevious studies of professional basketball athletes have characterized manifestations of athletic remodeling by echocardiography and electrocardiography (ECG) in males and echocardiography in females. There is a paucity of female, basketball-specific ECG data.ObjectiveTo generate reference range ECG data for female professional basketball athletes.Design, Setting, and ParticipantsThis is a cross-sectional study of ECGs performed on female professional basketball athletes. The Women’s National Basketball Association mandates annual preseason ECGs and echocardiograms for each athlete and has partnered with Columbia University Irving Medical Center to annually review these studies. Data for this study were collected during preseason ECG and echocardiography cardiac screening between April and May 2022. Data analysis was performed between February and July 2023.ExposureAthlete ECGs and echocardiograms were sent to Columbia University Irving Medical Center for core lab analysis.Main Outcomes and MeasuresQuantitative ECG variables were measured. ECG data were qualitatively analyzed for training-related and abnormal findings using the International Recommendations for Electrocardiographic Interpretation in Athletes. Findings from ECGs were compared with corresponding echocardiographic data.ResultsThere were a total of 173 athletes (mean [SD] age 26.5 [4.1] years; mean [SD] height, 183.4 [9.1] cm; mean [SD] body surface area, 2.0 [0.2] m2), including 129 Black athletes (74.5%) and 40 White athletes (23.1%). By international criteria, 136 athletes (78.6%) had training-related ECG changes and 8 athletes (4.6%) had abnormal ECG findings. Among athletes with at least 1 training-related ECG finding, left ventricular structural adaptations associated with athletic remodeling were present in 64 athletes (47.1%). Increased relative wall thickness, reflecting concentric left ventricular geometry, was more prevalent in athletes with the repolarization variant demonstrating convex ST elevation combined with T-wave inversions in leads V1 to V4 (6 of 12 athletes [50.0%]) than in athletes with early repolarization (5 of 42 athletes [11.9%]) (odds ratio, 7.40; 95% CI, 1.71-32.09; P = .01). Abnormal ECG findings included T-wave inversions (3 athletes [1.7%]), Q waves (2 athletes [1.2%]), prolonged QTc interval (2 athletes [1.2%]), and frequent premature ventricular contractions (1 athlete [0.6%]).Conclusions and RelevanceThis cross-sectional study provides reference ECG data for elite female basketball athletes. International criteria–defined training-related findings were common, whereas abnormal ECG findings were rare in this athlete group. These reference data may assist basketball programs and health care professionals using ECGs in screening for female athletes and may be used as a stimulus for future female-specific ECG inquiries.

女性职业篮球运动员的心电图检查结果

重要性以前对职业篮球运动员的研究已经通过超声心动图和心电图（ECG）对男性和女性超声心动图描述了运动重塑的表现。女性篮球专用心电图数据很少。目的为女性职业篮球运动员生成参考范围心电图数据。设计、设置和参与者这是对女性职业篮球运动员进行的心电图横断面研究。美国女子篮球协会要求每位运动员每年进行季前心电图和超声心动图检查，并与哥伦比亚大学欧文医学中心合作，每年审查这些研究。这项研究的数据是在 2022 年 4 月至 5 月季前心电图和超声心动图心脏筛查期间收集的。数据分析是在 2023 年 2 月至 7 月之间进行的。Exposure运动员心电图和超声心动图被发送至哥伦比亚大学欧文医学中心进行核心实验室分析。主要结果和措施定量测量心电图变量。使用《运动员心电图解读国际建议》对心电图数据进行定性分析，以找出与训练相关的异常结果。将心电图结果与相应的超声心动图数据进行比较。结果共有 173 名运动员（平均 [SD] 年龄 26.5 [4.1] 岁；平均 [SD] 身高，183.4 [9.1] cm；平均 [SD] 体表面积，2.0 [0.2] 米2），其中包括 129 名黑人运动员（74.5%）和 40 名白人运动员（23.1%）。根据国际标准，136 名运动员（78.6%）出现与训练相关的心电图变化，8 名运动员（4.6%）出现异常心电图结果。在至少有 1 次训练相关心电图发现的运动员中，64 名运动员 (47.1%) 存在与运动重塑相关的左心室结构适应。相对壁厚增加（反映同心左心室几何形状）在具有复极变异的运动员中更为普遍，这些复极变异表现为 V1 至 V4 导联 T 波倒置（12 名运动员中的 6 名[50.0%]）出现凸状 ST 抬高，而早起的运动员则更常见。复极（42 名运动员中有 5 名 [11.9%]）（比值比，7.40；95% CI，1.71-32.09；磷= .01)。心电图异常结果包括 T 波倒置（3 名运动员 [1.7%]）、Q 波（2 名运动员 [1.2%]）、QTc 间期延长（2 名运动员 [1.2%]）和频繁室性早搏（1 名运动员 [0.6]） %]).结论和相关性这项横断面研究为优秀女子篮球运动员提供了参考心电图数据。国际标准定义的与训练相关的发现很常见，而异常心电图发现在该运动员组中很少见。这些参考数据可以帮助篮球项目和医疗保健专业人员使用心电图筛查女运动员，并可以用作未来女性特定心电图查询的刺激。
