O protocolo estabelecido pela FEI para os Polares Digitais

1- O monitor mede a frequência cardíaca com 15 segundos. Se for 59 ou menos, o cavalo está aprovado.

2- Se for 60 ou mais a contagem continua até o minuto cheio. Ao final dos 60 segundos, se a frequência for 64 ou menos o cavalo está aprovado

3- Em situações normais, se ao final desse minuto a frequência for superior a 64bpm o cavalo deve sair do vet-check, ser resfriado novamente e se apresentar uma segunda vez

4- Se não houver tempo para uma segunda apresentação ou se a frequência alta acontecer já nessa 2a apresentação ou na apresentação final (quando não há direito a uma segunda chance) antes de eliminar o cavalo o veterinário deve pegar a frequência cardíaca novamente com outra máquina, por apenas 15 segundos (batimento máximo: 64bpm)

(f)Determining whether the Horse’s heart rate complies with the maximum heart rate parameters:
(i)If the heart rate is 5 bpm or more below the maximum heart rate parameter after the first 15-second time interval, then the reading may be recorded and the inspection completed. However, the Veterinarian may elect to continue the assessment for 60 seconds in case of any concern about the accuracy of the assessment.
(For example, if the maximum heart rate is 64bpm, the assessment may be stopped after the first 15-second time interval where i)the electronic heart rate monitor shows that the Horse’s heart rate is 59bpm or lower, or ii)the Veterinarian counts 14 heart beats or less using the stethoscope, because 14 x 4 = 56, whereas 15 x 4 = 60).
(ii)If the heart rate is within 4bpm, equal to, or greater than the maximum heart rate parameter after the first 15-second time interval, the assessment must continue for the full 60 seconds.
(For example, if the maximum heart rate is 64bpm, the assessment must continue for the full 60 seconds if after the first 15-second time interval i)the Horse’s heart rate is 60bpm or higher when using the electronic heart rate monitor, or ii)the Veterinarian counts 15heart beats or more using a stethoscope).
(iii)If after 60 seconds the Horse’s heart rate is equal to or less than the maximum heart rate parameter, then the reading will be recorded and the inspection completed.
(iv)If the heart rate is greater than the maximum heart parameter after the 60-second assessment:(A)Except for the Final Horse Inspection (where only one presentation is permitted), if there is sufficient time remaining for a second presentation (seeArticle 816.6), the Horse may be presented a second time for a heart rate re-inspection. The same procedures under paragraphs (a)-(f) above will apply to the second presentation. (B)If there is no time remaining for a heart rate re-inspection or the Horse fails to meet the maximum heart rate parameters at the heart rate re-inspection or at the Final Horse Inspection (where only one presentation is permitted), then a confirmation procedure must be completed to confirm the failed assessment. For the confirmation procedure, the Horse must be presented to a second Veterinarian immediately after the failed assessment. If an electronic heart rate monitor was used for the failed assessment, then a second electronic heart rate monitor(or, if not available, a stethoscope) must be used. The Veterinarian will assess the Horse’s heart rate for 15 seconds only. If the Horse is to be designated as ‘Failed to Qualify’, then the Horse’s heart rate during the confirmation procedure must either be made available on a public electronic display or notified toa member of the Ground Jury. If the Horse’s heart rate is greater than the maximum heart rate parameter during the confirmation procedure, the Horse will be designated as ‘Failed to Qualify –metabolic’ (FTQ-ME).
