Journal ArticleDOI
Human responses to upright tilt: a window on central autonomic integration
William H. Cooke,Jeffrey B. Hoag,Alexandra A. Crossman,Tom Kuusela,Kari U. O. Tahvanainen,Dwain L. Eckberg +5 more
TL;DR: Tilt reduces respiratory gating of sympathetic and vagal motoneurone responsiveness to stimulatory inputs for different reasons; during tilt, sympathetic stimulation increases to a level that overwhelms the respiratory gate, andvagal stimulation decreases to alevel below that necessary for maximal respiratory gates to occur.
Journal ArticleDOI
Time domain, geometrical and frequency domain analysis of cardiac vagal outflow: effects of various respiratory patterns.
Jani Penttilä,Antti Helminen,Tuomas Jartti,Tom Kuusela,Heikki V. Huikuri,Mikko P. Tulppo,René Coffeng,Harry Scheinin,Harry Scheinin +8 more
TL;DR: The quantitative geometrical analysis of short-term RRI variability from the Poincaré plots and the time domain measure RMSSD were not significantly affected by changes in the breathing rate, suggesting that these indices are more suitable for the measurement of cardiac vagal outflow during the 'free-running' ambulatory conditions.
Journal ArticleDOI
Heart rate variability biofeedback increases baroreflex gain and peak expiratory flow.
Paul M. Lehrer,Evgeny G. Vaschillo,Bronya Vaschillo,Shou-En Lu,Dwain L. Eckberg,Robert Edelberg,Weichung Joe Shih,Yong Lin,Tom Kuusela,Kari U. O. Tahvanainen,Robert M. Hamer +10 more
TL;DR: Heart rate variability biofeedback had strong long-term influences on resting baroreflex gain and pulmonary function and should be examined as a method for treating cardiovascular and pulmonary diseases.
Journal ArticleDOI
Human sympathetic and vagal baroreflex responses to sequential nitroprusside and phenylephrine
László Rudas,Alexandra A. Crossman,Carlos A. Morillo,John R. Halliwill,Kari U. O. Tahvanainen,Tom Kuusela,Dwain L. Eckberg +6 more
TL;DR: It is found that vagal baroreflex slopes are less when arterial pressures are falling than when they are rising and that this hysteresis exists over pressure ranges both below and above baseline levels.
Journal ArticleDOI
Vagal and sympathetic mechanisms in patients with orthostatic vasovagal syncope
Carlos A. Morillo,Dwain L. Eckberg,Kenneth A. Ellenbogen,Larry A. Beightol,Jeffrey B. Hoag,Kari U. O. Tahvanainen,Tom Kuusela,André Diedrich +7 more
TL;DR: Patients with orthostatic vasovagal reactions have impaired vagal baroreflex responses to arterial pressure changes below resting levels but normal initial responses to upright tilt.
