Electrocardiographic Studies on Neonatal Period of Holstein Dairy Calves

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

Yeni Doğan Holştayn Buzağılarda Elektrokardiyografik Çalışmalar

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
