...Hamish A. Campbell; Stuart Egginton SUMMARY The extent and efficiency of cardio-respiratory coupling (CRC) in teleost fishes is unclear. We simultaneously monitored heart rate (f H ) and ventilation rate (f V ) in Paranotothenia angustata, and applied modern power spectral analysis (PSA...

... ) was assessed by power spectral analysis (PSA). This mathematical technique provides a graphical output that enables the estimation of cardiac autonomic control by measuring periodic changes in the heart beat interval. At f h above 19 min -1 spectra were mainly characterised by low frequency components...

... (SDRR). Mean R–R interval increased to a steady state value (1.9±2.9 s) 72 h post-surgery, but SDRR took 120 h to stabilise (0.56±0.09 s). Power spectral analysis applied to recordings of instantaneous heart rate showed no spectral peaks immediately after surgery, with the development of twin peaks...
