This study analysed the psychological and psycho-emotional stress in cardiac surgery. Using heart rate variability (HRV) analysis, it is possible to record intraoperative objective stress responses in surgeons. The aim of the study was to assess with the help of HRV parameters the postulated increased stress levels of cardiac surgeons in training compared to experienced senior cardiothoracic surgeons in exactly the same work situation in order to make qualification-differentiated statements about physiological stress during surgical interventions.
During surgical teaching procedures, long-term ECG data ( = 15 each) for two operating residents and their assisting senior physicians were recorded. Time and frequency domain HRV parameters were analysed.
The time-related parasympathetic-dominated HRV parameters RMSSD (19.5 ms vs. 28.1 ms), NN50 (297.67 vs. 693.40), and cardiac interval mean RR (692.8 ms vs. 737.3 ms) indicate a higher stress level in the operating residents compared to the experienced surgeons. The higher stress index (11.61 vs. 8.86) confirms this.
Compared to experienced surgeons, operating residents showed lower parasympathetic activity and higher stress levels during cardiac surgery training procedures.
本研究分析了心脏外科手术中的心理和心理情绪压力。通过心率变异性（HRV）分析，可以记录外科医生术中的客观应激反应。该研究的目的是借助 HRV 参数评估受训心脏外科医生与经验丰富的心胸外科医生在相同工作环境下假定的应激水平升高情况，以便对手术干预期间的生理应激做出有区别的资格认定。
在手术教学过程中，记录了两名手术住院医师及其协助的资深医生的长期心电图数据（每组各 15 个）。分析了时域和频域 HRV 参数。
时间相关的副交感神经占主导地位的 HRV 参数 RMSSD（19.5 毫秒与 28.1 毫秒）、NN50（297.67 与 693.40）和平均 RR 间期（692.8 毫秒与 737.3 毫秒）表明手术住院医师的应激水平高于经验丰富的外科医生。更高的应激指数（11.61 与 8.86）证实了这一点。
与经验丰富的外科医生相比，手术住院医师在心脏手术培训过程中表现出较低的副交感神经活动和更高的应激水平。
