A new study has shown that short-term heart rate variability (ST-HRV) can be used to help detect sick sinus syndrome (SSS).

Heart rateScientists at the University of Wrocław in Poland have compared ST-HRV parameters in dogs with SSS or chronic mitral valve disease (CMVD) and healthy controls to verify the clinical application of ST-HRV analysis.


In an article published in the Polish Journal of Veterinary Sciences, the authors noted the study groups differed significantly in terms of both time and frequency domain ST-HRV parameters.

They concluded ST-HRV may be useful for the identification of dogs with SSS and the presence of dysautonomia in dogs with CMVD may be evaluated on ST-HRV analysis.
