Abstract

Abstract Using electrocardiography and echocardiography, we screened elite men and women ballet dancers for abnormal cardiovascular conditions using an observation design with blinded clinical analysis of cardiac function tests. Fifty-eight (females n = 33) elite professional ballet dancers (age: 26.0 ± 5.7 years, body mass index: 19.9 ± 2.2 kg/m2) with no past or present history of cardiovascular disease volunteered. Participants were assessed via a 12-lead electrocardiography and two-dimensional echocardiography for cardiac function. Electrocardiography revealed that 83% of the dancers demonstrated normal axis, while 31% had incomplete right bundle branch block and 17% had sinus bradycardia; none showed any abnormal findings. Findings from the echocardiography were also normal for all participants and comparable to their counterparts in other sports. Significant differences (p < 0.05) were detected in almost all studied echocardiographic parameters between males and females. In conclusion, heart function and structure seem to be normal in elite ballet dancers, placing them at low risk for sudden cardiac death and performance-related cardiovascular complications. Larger samples are required to confirm these findings.

舞者的心脏:精英舞者的心脏筛查

摘要:我们采用心功能试验的盲法临床观察设计，利用心电图和超声心动图筛选优秀男女芭蕾舞者的心血管异常情况。自愿招募58名优秀专业芭蕾舞演员(女性33名)，年龄26.0±5.7岁，体重指数19.9±2.2 kg/m2，既往无心血管疾病史。参与者通过12导联心电图和二维超声心动图评估心功能。心电图显示，83%的舞蹈者轴线正常，31%的舞蹈者有不完全性右束支阻滞，17%的舞蹈者有窦性心动过缓;没有任何异常的发现。超声心动图的结果对所有参与者来说都是正常的，与其他运动的参与者相当。男女之间几乎所有超声心动图参数均有显著差异(p < 0.05)。总之，优秀芭蕾舞者的心脏功能和结构似乎是正常的，这使他们发生心源性猝死和与表演相关的心血管并发症的风险较低。需要更大的样本来证实这些发现。
