ABSTRACT

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.

ÖZET

 

FARKLI YAŞ GRUPLARINDA SAĞLIKLI OLARAK GÖZLENEN SİYAH ALACA SIĞIRLARDA BASE APEKS DERİVASYONUNDAKİ STANDART ELEKTROKARDİYOGRAMDA ST SEGMENT ARALIĞININ VE MORFOLOJİSİNİN DEĞERLENDİRİLMESİ

 

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.
