Abstract (2. Language): 
The present study was conducted to obtain electrocardiographic data regarding the values of ST-segment morphology and duration from 84 apparently healthy Holstein cattle in fourteen different age groups from newborn to 7 years old. We recorded electrocardiograms in standard base apex lead system with the paper speed 25 mm/sec. and calibration of 10 mm equal to 1 mV. The morphologic assessments of electrocardiograms showed that all groups had normal isoelectric ST-segment, except newborns. Elevation of ST-segment was detected in 64.2% of newborn calves. The magnitude of this up sloping was 0.10±0.03 mV. The results of the comparison of ST-segment duration among different age groups showed that there were significant differences between the ST-segment duration of newborns (0.11±0.02, sec) and 5 years old (0.16±0.03, sec.), and also between 15 days (0.09±0.03, sec.) and 5 years old (P<0.05). The results of the present study may be accepted as normal ST-segment duration and morphology in different age groups of healthy Holstein cattle which will provide a good basis for judging and interpreting electrocardiograms.

Abstract (Original Language): 
Bu çalışmada yeni doğandan 7 yaşına kadar 14 farklı yaş grubunda bulunan 84 adet sağlıklı Siyah Alaca sığırda ST segment morfolojisi değerlerine ait elektrokardiyografik verilerin elde edilmesi amaçlanmıştır. Elektrokardiyogramlar standart base apeks derivasyon sisteminde, 25mm/sn kağıt hızında ve 1mV’ye eşit 10mm kalibrasyonda kayıt edilmiştir. Elektrokardiyogramların morfolojik değerlendirilmesi sonucunda yeni doğanlar haricinde tüm grupların normal izoelektrik ST segmentine sahip oldukları gözlenmiştir. Yeni doğanların %64,2’sinde ST segmentinde yükselme tespit edilmiştir. Bu yükselme miktarının eğimi 0,10±0,03 mV olarak saptanmıştır. ST segment aralığının farklı yaş grupları arasında karşılaştırılması sonucu; yeni doğanlar (0,11±0,02 sn) ile 5 yaşındakiler (0,16±0,03 sn) ve 15 günlük (0,09±0,03 sn) ile 5 yaşındakiler arasında önemli bir farklılık belirlenmiştir (P<0,05). Bu çalışmanın sonuçları, farklı yaş gruplarındaki sağlıklı Siyah Alaca sığırlarda ST segment aralığı ve morfolojisi normal olarak kabul edilerek, elektrokardiyogramların değerlendirilmesi ve yorumlanmasında iyi bir kaynak oluşturacaktır.
