Eloranta E Norberg H Nilsson A Pudas T Sakkinen H Individually coded telemetry a tool for studying heart rate and behaviour in reindeer calves Acta vet scand. 2002 43 135-144. - The aim of the study was to test the performance of a silver wire modified version of the coded telemetric heart rate monitor Polar Vantage NVTM PVNV and to measure heart rate HR in a group of captive reindeer calves during different behaviour. The technical performance of PVNV HR monitors was tested in cold conditions -30 C using a pulse generator and the correlation between generated pulse and PVNV values was high r 0.9957 . The accuracy was tested by comparing the HR obtained with the PVNV monitor with the standard ECG and the correlation was significant r 0.9965 . Both circadian HR and HR related to behavioural pattern were recorded. A circadian rhythm was observed in the HR in reindeer with a minimum during night and early morning hours and maximum at noon and during the afternoon the average HR of the reindeer calves studied being 42.5 beats min in February. The behaviour was recorded by focal individual observations and the data was synchronized with the output of the HR monitors. Running differed from all other behavioural categories in HR. Inter-individual differences were seen expressing individual responses to external and internal stimuli. The silver wire modified Polar Vantage NVTM provides a suitable and reliable tool for measuring heart rate in reindeer also in natural conditions. heart rate measuring technique method individual coding reindeer behaviour circadian.
