Key result
Cyclical neck suction increased the amplitude of respiratory sinus arrhythmia, with cardiac interval responses to respiration and neck suction being independent and algebraically additive.
Why the study?
Does cyclical neck suction alter the amplitude and phase of respiratory sinus arrhythmia in healthy subjects?
Does cyclical neck suction alter the amplitude and phase of respiratory sinus arrhythmia in healthy subjects?
The heart rate response to respiration and carotid baroreceptor stimulation are independent and summate algebraically in healthy subjects.

Supports additive respiratory and baroreflex effects on heart rate in healthy subjects; hypothesis-generating, requires validation before clinical consideration.
Cross et al. (1992) studied Healthy (n=6). Cyclical neck suction was evaluated on Amplitude and phase of respiratory sinus arrhythmia and cardiac interval response. Cyclical neck suction increased the amplitude of respiratory sinus arrhythmia, with cardiac interval responses to respiration and neck suction being independent and algebraically additive.
