Abstract

Objective: Arrhythmias due to congenital heart
diseases are found to be the second most common cause of mortality after
ischemic heart diseases
in several studies. Coarctation
of the aorta
,
hypertrophic  cardiomyopathy and aort
stenosis
increase afterload of the left ventricle
and as a result of this, they cause an 
increase in  wall
stress in the early and
hypertophy of the wall
in the late phase. This condition leads a corruption
in
ventricular and
atrial
conduction and predisposes
to arrhythmias. In this study, we
intended to examine the risks with indicators like P dis, QT dis, Tp-e  for arrhythmias in diseases with left
ventricular outflow tract
stenosis in children.

Method: 101 patients with with left ventricular outflow tract stenosis (coarctation of the aorta, idiopathic
hypertrophic subaortic stenosis, hypertrophic cardiomyopathy and aortic stenosis) in pediatric age group who
were diagnosed between
2008-2014 in Dr. Behçet Uz Children’s Training and Research Hospital were included in
this study.  110
healthy children were included in this
study as a control group.
Pdis, corrected QT, QT dis ve Tp-e and Tp-e /QT indices
in both groups were were calculated and compared  using standard 12-lead
ECG.

Results: P max, corrected QT, Pdis, QTdis, Tp-e and
Tp-e/QT in patient group were found to be significantly higher than
the control group. There
was no difference between sub-groups of patient group according to
Pmax, corrected QT, P dis, QT dis, Tp-e and Tp-e/QT. There
was also no difference between beta blocker users and non-users
according to
P max,
corrected QT, P dis, QT dis, Tp-e and Tp-e/QT.







Conclusions: High P max, corrected QT, P dis, QT dis, Tp-e
and Tp-e/QT in the patient group showed 
 the risk for ventricular arrhythmias and atrial fibrillation in patients with left ventricular outflow tract
stenosis.

Sol ventrikül çıkış yolu darlığı ve aort koarktasyonu olan olgularda aritmi belirteçleri

Year 2019, , 19 - 27, 28.03.2019

Abstract



Amaç: Konjenital kalp hastalıklarına
ait aritmilerin ani kardiyak ölüm riski açısından iskemik hastalıklara bağlı
aritmilerden sonra en sık mortalite nedeni olduğu gösterilmiştir. Aort
koarktasyonu, hipertrofik kardiyomyopati ve aort stenozu gibi hastalıkların
varlığında sol ventikül ard yükü belirgin artmakta bunun sonucu olarak da erken
dönemde artmış duvar stresi ve geç kompansatuvar ventrikül hipertrofisi ortaya
çıkmaktadır. Tüm bunlar da ventrikül ve atriyal iletimi bozarak aritmilere
yatkınlık oluşturabilmektedir. Bu çalışmada, çocukluk çağında sol ventrikül
çıkış yolunda darlığa yol açan kardiyak patolojilerde aritmilere yatkınlığın
ortaya konması amaçlanmıştır.



Yöntem: 2008-2014 yılları arasında tanısı konan
ve hastanemizde izlenen sol ventrikül çıkış yolunda darlığa neden olacak
kardiyak patolojisi olan 101 hasta çalışmaya dahil edildi. Kontrol grubu olarak
110 sağlıklı çocuk alındı.
Standart 12 derivasyonlu EKG’de hastaların P dispersiyonu(dis),
QTd(değişkenlik), QT intervali, QTdis ve Tp-e ve Tp-e /QT indeks değerleri
hesaplandı.



Bulgular: Hasta grubunda Pmaks, QTd,
Pdis, QTdis, Tp-e ve Tp-e/QT indeksleri kontrol grubuna göre belirgin yüksek
saptandı. Hasta grubunu oluşturan alt gruplarda Pmaks, QTd, Pdis, QTdis, Tp-e
ve Tp-e/QT indeksleri açısından gruplar arası anlamlı istatistiksel fark
saptanmadı. Beta bloker kullanan ve kullanmayan hasta gruplarında da bu
parametreler 
açısından anlamlı fark saptanmadı.

Sonuç: Çalışmamızda
aritmi belirteçleri olarak değerlendirdiğimiz Pmaks, Pdis, QTd,
QTdis, Tp-e, Tp-e/QT hasta grubunda kontrol grubuna göre belirgin artmış
izlenmiş ve bu da bu hastaların hem
atriyal fibrilasyon hem de ventriküler aritmiler açısından risk altında
olduğunu göstermiştir.
