Abstract:Objectives
To study the impact of respiratory frequency on HRV and discuss how to exclude it.
Methods
12 healthy male rabbits aged 4-5 months and weighting 2.5-3.0 kg were selected. The Rabbits respiratory control system was established. ECG, instant blood pressure and respiratory waveform under different respiratory frequency (RF) (40 bpm,50 bpm,60 bpm) were recorded synchronously via SKY-A4 (a three channel electrophysiolograph); HRV & BRS2.0-a HRV analysis system was used to observe the shift of high freq… Show more
