Decreasing cerebral oxygen consumption during upright tilt in vasovagal syncope

Physiological Reports, 2017
We measured changes in transcranial Doppler ultrasound (TCD) and near infrared spectroscopy (NIRS) during 70° upright tilt in patients with recurrent vasovagal syncope (VVS, N = 20), postural tachycardia syndrome (POTS, N = 20), and healthy controls (N =
