SAÐLIKLI PREMATÜRELERDE ELEKTROKARDÝOGRAFÝK BULGULAR VE DEÐERLENDÝRÝLMESÝ

Doðum tartýlarý 1100 ile 2300 gr arasýnda deðiþen 30 prematüre bebeðin EKG'lerin incelendi. Olgularýn %65'inde sað aks, %35'inde nötral aks bulundu. Düþük tartýlý gurupta (>1500 gr) sað aks deviasyonu daha azdý. Prematürelerdeki EKG traselerinin, terminde doðanlara göre eriþkin patternine kaydýðý gözlendi.PR süresi (D2'de) 1500 gr'ýn altýndaki gurupta ortalama 0.09", diðer gurupta ise 0.094" bulundu. P amplitüdü ise (ayný derivasyonda), I. gurupta (1500 gr'ýn altý) ortalama 1,8 mm, diðer gurupta 1.5 m bulundu. Bu deðerler miyadýnda doðanlara göre, P amplitüdü yüksek, PR süresi ise kýsa bulunmuþtur. QRS süresi, düþük aðýrlýklý gurupta daha fazla olmak üzere kýsa, QRS voltajý ise her iki prematüre gurubunda belirgin derecede farklý olmamak üzere düþük bulunmuþtur. Ayrýca deðerlendirmelerin doðru yapýlabilmesi için çekim tekniðine çok dikkat etmek gerektiði vurgulanmýþtýr.

THE EVALUATION OF THE ECG FINDINGS OF HEALTHY PREMATURE BABIES

The ECG's of 30 premature babies with birth weights ranging between 1100-2300 gr were evaluated. In %65 of the cases, right axis, in %35 of them neutral axis was found. In the low birth weight group (> 1500 gr)the incidence of right axis deviation was lower. The ECG pattern of premature babies, when compared to the term babies, was similar to the adult pattern. The PR interval (in D2 derivation) was 0.09 sec in the group smaller than 1500 gr while it was 0.094 sec in the other group. The amplitude of P wave in the same derivation was1.S mm in the first group and 1.5 mm in the second group. When compared to the values found in tern babies, the amplitude of P wave was higher, whereas the PR interval was shorter. The QRS interval was found to be short according to the term babies and shorter in the low birth weight group. The voltage of QRS was low in both groups with no significant difference between these groups. It is emphasized that in order to have a re liable ECG evaluations, the ECG recordings of premature babies must be applied by experienced people with extreme care for technical details.
