We compared measures of the sympatho-vagal balance in heart regulation and cardiovagal baroreflex sensitivity (BRS) between musicians playing wind instruments ( n = 23) and non-musicians ( n = 19) to elucidate whether playing wind instruments is associated with chronic alterations in autonomic cardiovascular control. The arterial blood pressure was measured and ECG was recorded under resting conditions, and the Valsalva maneuver was conducted. The main HRV parameters were calculated, and BRS values were estimated using a sequence method. Musicians were characterized by a higher average heart rate at rest, lower values of the parasympathetic-related HRV parameters, i.e., RMSSD, pNN50%, HF, and SD1, together with lower values of SDNN and total HRV power. The Valsalva maneuver estimates (BRS) did not differ significantly between musicians and non-musicians. Thus, certain HRV parameters differed significantly between the examined groups. Musicians were characterized, in general, by lower vagal activity and sympathetic predominance. There was no difference in the BRS.

演奏乐器的音乐家心脏功能自主调节的特点

我们比较了演奏管乐器的音乐家 (n = 23) 和非音乐家 (n = 19) 的心脏调节和迷走神经压力反射敏感性 (BRS) 的交感 - 迷走神经平衡的测量，以阐明演奏管乐器是否与慢性改变有关自主心血管控制。在静息状态下测量动脉血压并记录心电图，并进行Valsalva动作。计算主要 HRV 参数，并使用序列方法估计 BRS 值。音乐家的特点是静息时平均心率较高，副交感神经相关 HRV 参数值较低，即 RMSSD、pNN50%、HF 和 SD1，以及 SDNN 和总 HRV 功率值较低。Valsalva 动作估计值 (BRS) 在音乐家和非音乐家之间没有显着差异。因此，某些 HRV 参数在检查组之间存在显着差异。一般来说，音乐家的特点是迷走神经活动较低，交感神经占优势。BRS 没有区别。
