Journal ArticleDOI

Mechanisms of respiratory sinus arrhythmia in patients with mild heart failure.

TL;DR: The results indicate that the HF component can significantly overestimate cardiac vagal responsiveness in patients with mild chronic heart failure and this bias is improved by controlled breathing, since this maneuver increases the vagal contribution to HF without affecting its nonneural component.
Journal ArticleDOI

Effects of mild physical activity, atenolol and the combination on ambulatory blood pressure in hypertensive subjects.

TL;DR: Atenolol did not enhance the effect of physical training upon blood pressure and had little if any effect upon the training-induced increase in exercise tolerance.
Journal ArticleDOI

Sympathetic activation increases NO release from eNOS but neither eNOS nor nNOS play an essential role in exercise hyperemia in the human forearm.

TL;DR: It is suggested that sympathetic activation increases NO release from eNOS, attenuating vasoconstriction, even in the presence of increased sympathetic activation.
Journal ArticleDOI

Regulation of β-adrenergic control of heart rate by GTP-cyclohydrolase 1 (GCH1) and tetrahydrobiopterin

TL;DR: Reduced GCH1 expression and BH4 deficiency cause tachycardia through enhanced β-adrenergic sensitivity, with no effect on vagal function, and are novel determinants of cardiac autonomic regulation that may have important roles in cardiovascular pathophysiology.
