Electrocardiographic Studies on Neonatal Period of Holstein Dairy Calves

Year 2015, Volume: 41 Issue: 2, 167 - 171, 04.07.2015

Abstract

Several physiological alterations may occur in cardiovascular system during fetal life to the neonatal period. Electrocardiographic studies in neonatal period may assist veterinarians to evaluate cardiovascular system in this period. Five multiparous high producing Holstein dairy cows were monitored at close-up dry period to calving. Electrocardiograms were recorded from their calves immediately and 5, 10, 15, 20, 25, 30 and 35 days after birth and all electrocardiographic parameters were evaluated. Durations of P, R and T waves were increased significantly from birth to the end of neonatal period (P<0.05). R and T amplitudes were significantly elevated but P amplitude declined significantly. There were significant increasing patterns in PR, RR, QT and ST intervals during neonatal period (P<0.05). Based on these findings, it may be suggested that physiological alterations of the electrocardiographic parameters occur during the neonatal period of the Holstein dairy calves at neonatal period. These data could provide a better understanding of interpretation of the electrocardiographic alterations among neonatal calves.

Yeni Doğan Holştayn Buzağılarda Elektrokardiyografik Çalışmalar

Year 2015, Volume: 41 Issue: 2, 167 - 171, 04.07.2015

Abstract

Fötal hayattan yeni doğan dönemine kadar kardiyovasküler sistemde çeşitli fizyolojik değişiklikler meydana gelebilir. Yeni doğan dönemindeki elektrokardiyografi çalışmaları, bu dönemdeki kalp-damar sisteminin durumunu değerlendirmek için veteriner hekimlere yardım edebilir. Yüksek süt üretimine sahip, birden fazla doğum yapmış olan beş adet Holştayn inek kuru dönemden buzağılamaya kadar takip edilmiştir. Elektrokardiyogramlar doğumdan hemen sonra buzağıların doğumunu takibinden 5, 10, 15, 20, 25, 30 ve 35 gün sonra kaydedilmiştir ve tüm elektrokardiyografik parametreler değerlendirilmiştir. Doğumdan yeni doğan dönemin sonuna kadar P, R ve T dalgalarının süreleri anlamlı olarak artmıştır (P<0,05). R ve T amplitüdleri anlamlı olarak yükselmiş ancak P amplitüdünde önemli ölçüde düşüş bulunmuştur. Yeni doğan döneminde PR, RR, QT ve ST aralıklarında önemli artışlar gözlenmiştir (P<0,05). Bu bulgulara dayanarak, yeni doğan döneminde Holştayn buzağılara ait elektrokardiyografik parametrelerdeki fizyolojik değişikliklerin, yeni doğan döneminde ortaya çıktığı söylenebilir. Bu veriler, yeni doğan buzağılarda elektrokardiyografik değişikliklerin yorumlanmasının daha iyi anlaşılmasını sağlayabilir.
