Exercise was found to produce pseudoischemic changes of ST segment in 6% of patients with neurocirculatory dystonia, and T-wave inversion in 15-16%, which may be due to hyperventilation. It was demonstrated that T-wave inversion could not be a reliable indicator of coronary insufficiency, nor could respiratory alkalosis, hypocapnia, tachycardia, increased work of respiratory muscles, hypoxemia be immediate causes of hyperventilation changes. It is suggested that the changes in question are related to disrupted vegetative control of the cardiovascular system.
研究发现,在6%的神经循环性肌张力障碍患者中,运动可导致ST段出现假性缺血性改变,15%-16%的患者出现T波倒置,这可能是由于过度通气所致。结果表明,T波倒置并非冠状动脉供血不足的可靠指标,呼吸性碱中毒、低碳酸血症、心动过速、呼吸肌做功增加、低氧血症也不是过度通气改变的直接原因。有人认为,上述改变与心血管系统自主神经调节紊乱有关。
