Approach and Treatment for Breath-Holding Spells with Seizures
For children experiencing breath-holding spells with seizures, the recommended treatment includes iron supplementation for those with iron deficiency, midodrine for persistent cases, and cardiac pacing for severe cases with documented asystole. 1
Understanding Breath-Holding Spells
- Breath-holding spells are common, benign events affecting 0.1-4.6% of otherwise healthy young children, typically with onset between 6-18 months of age 2
- These spells are classified into two main types:
- Both types typically last 10-60 seconds and usually resolve spontaneously by 5 years of age 2
- Seizure-like activity may occur during severe episodes due to cerebral hypoperfusion, not representing true epilepsy 3, 4
Diagnostic Approach
- Obtain a detailed medical history focusing on:
- Physical examination should be performed to rule out underlying conditions 2
- Perform a standard 12-lead ECG to exclude cardiac conditions, particularly long QT syndrome 1, 5
- EEG is generally not necessary unless there are atypical features suggesting true epilepsy 5
- Consider hemoglobin assessment to evaluate for iron deficiency 2
Treatment Algorithm
First-line approach:
For children with iron deficiency:
- Iron supplementation should be provided, as it has been shown to reduce frequency and severity of spells 1
For persistent, severe cases:
For severe cases with documented asystole:
- Cardiac pacing may be considered, with studies showing 86% of infants and toddlers experiencing either complete resolution or significant reduction in syncopal events 1
Alternative pharmacological options:
- Piracetam (50-100 mg/kg/day) may be effective for severe breath-holding spells, with studies showing complete resolution in 81% of children 6
Important Considerations and Cautions
- Beta-blockers are not recommended for pediatric patients with vasovagal syncope, as studies show they may actually increase recurrence rates 1
- During episodes:
- For seizures lasting >5 minutes, emergency medical services should be activated 3
- In rare cases, psychological factors may contribute to breath-holding spells, and addressing parent-child relationship issues may be beneficial 7
- Cardiac pacing should be approached cautiously due to potential long-term complications and the fact that pallid breath-holding syncope typically resolves spontaneously with age 1
When to Seek Emergency Care
- First-time seizure or seizure in an infant <6 months of age 3
- Seizure lasting >5 minutes 3
- Multiple seizures without return to baseline mental status between episodes 3
- Failure to return to baseline within 5-10 minutes after seizure activity stops 3
- Seizure with traumatic injuries or difficulty breathing 3
