| Abstrakt: | Objectives: Reflex anoxic syncope is the result of an overreaction of the vagal system, resulting in hypotension and bradycardia or brief cardiac arrest. Because of the benign character and the absence of complications in short or long term, treatment is only necessary in case of frequent or severe clinical presentation. Treatment options are anticholinergic drugs or cardiac pacemaker placement. We investigated atropine treatment and aimed to examine if pacemaker placement can be avoided. Methods: We retrospectively reviewed patients treated with atropine for severe reflex anoxic syncope in our centre from January 2017 until May 2023, and compared our results to those in the literature. Results: The study population consisted of 10 children, 70% female, with an age ranging from 5 months to 3 years (mean 14.5 months) when atropine treatment was started (dose 17-50 microg/kg/day). All patient's parents reported adequate symptom management during atropine treatment, with complete resolution in 10%. Minor side effects were reported in 60% (dry mucosa in 40%, obstipation in 20%, and nausea or blurry vision in 10%). Discussion: We consider atropine a safe and effective treatment to manage reflex anoxic syncope with similar success rate to pacemaker implantation. However, pacemaker implantation entails substantial risk for complications (up to 25%) such as infection or technical problems and morbidity such as scar formation. This might be considered redundant for a benign and temporary condition, certainly given the possibility of other efficient treatment options. Consequently, we recommend atropine treatment over implantation of a cardiac pacemaker in children with severe reflex anoxic syncope. |
