[Hemodynamic changes in healthy persons and in patients with arterial hypertension during hyperventilation].
Hemodynamic changes in response to the hyperventilation test were examined in normal males and females of varying age, and in patients with first- and second-stage essential hypertension, renal arterial hypertension and hypertensive neurocirculatory dystonia. Normal subjects showed increased heart rate (HR) and cardiac index (CI), and lowered specific peripheral resistance in response to hyperventilation, the magnitude of HR and CI changes declining with age. The increase in HR and CI during the test was somewhat more pronounced in patients with essential hypertension as compared to normal subjects, whereas in hypertensive neurocirculatory dystonia hemodynamic shifts were similar to those of normal subjects.
