EVALUATION OF P WAVE DISPERSION IN ECG; QT DISPERSION AND OTHER ECG CHANGES IN PATIENTS ADMITTED TO EMERGENCY DUE TO STROKE

Abstract

Aims: In this, a comparison ofQT, QTc, QTdis, P wave and Pdis values from the first ECG recordings in stroke patients and healthy individuals in emergency department was realized, and it was searched whether these values were predictors of prognosis within gender and age or not.

Materials and methods:Along with a control group of  90 patients, 76 patients with a diagnosis on ischemic stroke presenting neurological symptoms and brain CT and / or MRI evaluation in the emergency room were included in the study. All patients were analysed with 12-lead electrocardiograms and PMAX, PMIN, pdis, QT, QTc, QTDIS and QTCDIS intervals were measured.

Results:During the Pdis comparison in control and stroke groups, interval wasdetected significantly higher in the stroke group[95% CI; 39.55 to 49.40] compared to the control group [95% CI; 26.55 to 33.45]. QTDİS[95% CI; Vs 49.16 to 62.28 39.28 to 46.82] and QTCDİSvalues [95% CI; 54.22 to 72.83 vs 43,10-51,1739,28-46,82] werealso detected statistically meaningful in stroke group compared to control cases.

Conclusion:Pdis, QTDIS and QTCDIS intervals that were determined to be prolonged in stroke gropus compared to the control group should be considered as important parameters in prognosis and clinical follow-up.

İNMEYLE BAŞVURULAN ACİL DURUM HASTALARINDA: P DALGA DİSPERSİYONU, QT DISPERSION VE DİĞER EKG DEĞİŞİKLİKLERİ

Abstract

Amaç: Bu çalışmada, acil serviste  inme hastalarında ve sağlıklı bireylerde ilk EKG kayıtlarından QT, QTc, QTdis, P dalga ve Pdis değerlerinin karşılaştırılması yapıldı ve bu değerlerin cinsiyet ve yaş açısından prognoz belirleyicileri olup olmadığı araştırıldı.Gereç ve yöntem: 90 hastadan oluşan bir kontrol grubu ile birlikte, nörolojik semptomları olan ve iskemik inme tanısı konan 76 hastanın acil serviste beyin BT ve / veya MRG değerlendirmesi yapıldı. Tüm hastalar 12 derivasyonlu elektrokardiyografi ile analiz edildi ve PMAX, PMIN, pdis, QT, QTc, QTDIS ve QTCDIS aralıkları ölçüldü.

Bulgular: Kontrol grubu ve inme gruplarındaki Pdis karşılaştırması sırasında, aralık inmeli grupta [% 95 CI; 39.55 ila 49.40] kontrol grubuna [% 95 CI; 26.55 ila 33.45]. QTDİS [% 95 CI; Vs 49.16 ila 62.28 39.28 ila 46.82] ve QTCDİS değerleri [% 95 CI; 54.22 ila 72.83'e karşılık 43,10-51,1739,28-46,82] kontrol gruplarına kıyasla inmeli grupta istatistiksel olarak anlamlı bulundu.

Sonuç: Prognoz ve klinik takipte inme grubunda kontrol grubuna göre uzamış olduğu saptanan Pdis, QTDIS ve QTCDIS değerleri önemli parametreler olarak düşünülmelidir.
