Abstract

Aim: The aim of this study was to determine the effectiveness and safety of propafenone in children, referred to the pediatric cardiology outpatient clinic of Istanbul Medical Faculty. Materials and Methods: Twenty-two patients with an average age of 10.9$pm$3.6 years were investigated. Ventricular premature beat frequency has been determined by 24-hour Hotter monitorization in patients who were physically and biochemically checked. Patients between 4 and 16 years of age with ventricular dysrhythmia on electrocardiography (ECG), who had symptoms at stage II or no symptoms at stage III or higher stages according to Lown classification, were included in the study. Propafenone treatment with a mean dose of 10.7±1.1 mg/kg/day was given to patients. Fifteen of the patients who responded to the treatment were followed for I year. Controls were performed at the first week and 1st, 3rd, 6th, 12th months during the follow-up. Each evaluation included physical examination, 12-lead ECG, 24-hour Holier monitoring and echocardiography. Complete blood count and biochemical analysis were performed before treatment, at 6th and 12th monthly controls. Results: When all the parameters were statistically evaluated, it was determined that the daily number of ventricular premature beats and maximum heart rate decreased significantly. At the end of one year follow up, number of ventricular premature heats were decreased from 4253 ±1885 to 651 ±232 (p< 0.001) and the maximum heart rate decreased from 128$pm$17 to 112±9 (p<0.05) .Ventricular premature beat frequency decreased more than 80 % in half of the cases. The treatment was completely succesful in 50 % of the patients while 18.2 % of patients partially responded. With propafenone treatment, ventricular tachycardia attacks disappeared in three out of 8 cases, but other 5 cases with sustained VT had no response. Side effects were observed in six patients; lack of appetite in three patients, nausea in one patient, slight depression of left ventricular systolic function in one patient and presyncope in one patient. Conclusion: We may conclude that propafenone is effective and safe in the treatment of ventricular dysrhythmias in children.

Özet

Amaç: İ. Ü. İstanbul Tıp Fakültesi Çocuk Sağlığı ve Hastalıkları Anabilim Dalı Çocuk Kardiyolojisi Polikliniği'ne başvuran, kronik ventrildiler disritmili hastalarda, propafenonım etkinliğini ve güvenilirliğinin belirlenmesi hedeflendi. Gereç ve Yöntem: Yaş ortalaması 10.9$pm$3.6 yıl olan 22 hastanın, fizik muayeneleri ve laboratuar tetkikleri yapıldı. Ventriküler erken vuru sıklığı, 24 saatlik Halter monitorizasyonu ile saptandı. Yüzeyel elektrokardiyografi (EKG) ile ventriküler disritmi tanısı alan ve 24 saatlik Halter monitorizasyonda, Lown sınıflamasına göre evre III ve üzerindeki asemptomatik hastalar ile evre II ve üzerinde semptomatik olan 4 ile 16 yaş arası hastalar çalışmaya alındı. Hastalara ortalama l0.7±1l mg/kg/gün dozunda propafenon tedavisi haşlandı. Tedaviye yanıt veren 15 vaka l yıl boyunca izlendi. İlaca başlandıktan sonraki ilk hafta ve daha sonraki 1., 3., 6. ve 12. aylarda kontrol muayeneleri yapıldı. Her kontrolde fizik muayene, ekokardiyografi ve Hotter monitorizasyonu tekrarlandı. Kan sayımı ve biyokimyasal, tetkikler ise, tedavi öncesi, 6. ve 12. aylarda yapıldı. Bulgular: Tüm bu parametrelerin istatistiksel değerlendirilmesi sonucunda, günlük ventriküler erken vuru sayısı ve maksimum kalp hızlarında anlamlı bir azalma saptandı. Bir yıllık izleme sonunda, ventriküler erken vuru sayısı 4253$pm$1885'den 651±232'ye (p<0.001), maksimum kalp hızı 128$pm$17 den 112$pm$9 a indi (p<0.05). Vakaların % 50'sinde ventriküler erken vuru sıklığı % 80'den fazla azaldı. Çalışmanın başarı kriterlerine göre, vakaların % 50'sinin tedaviye tam, % 18.2'sinin ise kısmi yanıt verdiği gözlendi. Propafenon tedavisi ile ventriküler taşikardi atakları bulunan 8 vakanın üçünde bu ataklar kaybolurken, geriye kalan sürekli "sustained" ventriküler taşikardili 8 vakada yanıt alınamadı. Üç hastada (% 13.7) iştahsızlık, bir hastada bulana, bir hastada sol ventrikül sistolik fonksiyonlarında azalma ve bir hastada presenkop olmak üzere toplam altı hastada çeşitli yan etkiler gözlendi. Sonuç: Propafenonun, çocukluk çağı ventriküler disritmilerinin tedavisinde etkili ve güvenilir bir ilaç olduğu kanısına varıldı.
