Why the study?
The effects of hyperventilation and hyperventilation during periodic breathing on sympatho-vagal balance and hemodynamics in conditions like HF or PAH are not completely understood.
Does voluntary hyperventilation and simulated periodic breathing alter hemodynamics and sympatho-vagal balance in patients with heart failure or pulmonary arterial hypertension compared to healthy subjects?

Simon-Dominik Herkenrath (2021) conducted a cross-sectional in Heart failure and pulmonary arterial hypertension (n=60). Voluntary hyperventilation and simulated periodic breathing vs. Baseline was evaluated on Hemodynamics and sympatho-vagal balance (diastolic blood pressure, heart rate variability, baroreceptor-reflex sensitivity, total peripheral resistance index, and cardiac index).
