“…Breath-holding spells usually occur in the breast-feeding period and disappear spontaneously before school age (Akalin et al, 2004). The youngest case in the literature is a 3-day-old infant with positive family history, whereas the oldest case involves a patient aged 11 years 8 months (Breukels et al, 2002;Low et al, 1955).…”

“…The youngest case in the literature is a 3-day-old infant with positive family history, whereas the oldest case involves a patient aged 11 years 8 months (Breukels et al, 2002;Low et al, 1955). The attacks often occur with emotional stimuli or after minor trauma; they are characterized by endexpiratory respiratory arrest, color change in the skin, and a change or loss of consciousness or postural tone (Akalin et al, 2004;Guilleminault et al, 2007). Although the exact etiology is unknown, the most common suspected risk factor is iron deficiency, with or without anemia (Algarin et al, 2003;Kurekci et al, 2006).…”

“…Although the exact etiology is unknown, the most common suspected risk factor is iron deficiency, with or without anemia (Algarin et al, 2003;Kurekci et al, 2006). However, several studies have demonstrated an autonomic dysfunction in children with BHS, and the degree of autonomic dysfunction has been reported to correlate with the severity of the disease (Akalin et al, 2004;DiMario, 1992;Kolkiran et al, 2005).…”

“…However, our results show that patients with cyanotic BHSs had an increased duration of bradycardia and arrhythmia after spells, despite the absence of a difference in ECG measures of ventricular repolarisation to those patients with pallid spells. Similarly, other studies found no difference in terms of ventricular repolarisation parameters between patients with cyanotic or pallid spells.…”

Objective: A breath-holding spell (BHS) is a clinical feature frequently seen in infancy and early childhood and generally bringing children to pediatric cardiology outpatient clinics with the suspicion of cardiac disease. In this study, P wave dispersion (PWD), which is a marker of regional differences in atrial depolarization in electrocardiography and has been demonstrated to be beneficial in defining the risk of supraventricular tachycardia in various patient groups, was studied in children who presented with breath-holding spells. Materials and Methods:Forty-seven patients with breath-holding spells and 36 healthy children as a control group were included in this study. We performed electrocardiography and transthoracic echocardiography on patients and controls. PWD, which is defined as the difference between maximum and minimum p wave duration, was also calculated. Statistical analysis in the study was performed using SPSS version 22.0 and p<0.05 was accepted as significant. Results:Our study indicated that there were no statistically significant differences between the patients and controls in minimum, maximum p wave duration and PWD. Conclusion:Our findings suggest that atrial conduction is probably unaffected in children with breath-holding spells.Keywords: Breath-holding spells, electrocardiography, p wave dispersion, supraventricular tachycardia Amaç: Soluk-tutma nöbetleri sıklıkla süt çocukluğu ve erken çocukluk çağında görülen ve kalp hastalığı şüphesiyle çocuk kardiyoloji kliniklerine çocukların götürüldüğü klinik bir tablodur. Bu çalışmada elektrokardiyografide (EKG) atriyal depolarizasyona ait bölgesel farklılıkların bir göstergesi olan ve çeşitli hasta gruplarında supraventriküler taşikardi riskini belirlemede yararlı olduğu kanıtlanmış olan p dalga dispersiyonu soluk tutma nöbeti ile başvurmuş çocuklarda çalışılmıştır. Gereç ve Yöntem:Çalışmaya hasta grubu olarak 47 soluk-tutma nöbetli ve kontrol olarak da 36 sağlıklı çocuk alınmıştır. Her 2 gruba EKG ve ekokardiyografi yapılmıştır. P dalga dispersiyonu, maksimum ve minimum p dalga süreleri arasındaki fark olarak hesaplanmıştır. İstatistiksel analizde SPSS 22.0 programı kullanılmış olup p<0,05 anlamlı olarak kabul edilmiştir. Bulgular:Hasta ve kontrol grubunda p minimum, p maksimum ve p dalga dispersiyonu süreleri arasında anlamlı farklılık bulunmamıştır.Sonuç: Soluk-tutma nöbetli çocuklarda atrial iletinin olasılıkla etkilenmediği gösterilmiştir.Anahtar Kelimeler: Soluk-tutma nöbeti, elektrokardiyografi, p dalga dispersiyonu, supraventriküler taşikardi Sum mary Öz 117Original Article / Özgün Araştırma DO I:10.4274/tnd.72623 Turk J Neurol 2016;22:117-120

Increased QT dispersion in breath‐holding spells

Abstract: QT dispersion is increased in patients with breath-holding spells, and this finding justifies further investigation for rhythm abnormalities and autonomic dysfunction in this patient group.
