Recommendation for action according to the guidelines "Bradycardiac arrhythmias in childhood and adolescence"
Abstract
In bradycardic cardiac arrhythmias, there is a temporary or permanent abnormally reduced heart rate relative to age. Clinically important forms are the congenital and the acquired high-grade atrioventricular block (AV block II ° type 2, transition> 2: 1) as well as the complete atrio-ventricular block (AV block III °), the sinus bradycardia, the bradycardia tachycardia syndrome and the bradycardia-induced tachyarrhythmias.
Bradycardia is associated with a reduced cardiovascular volume. Key symptoms are a reduced resilience to manifest heart failure, dizziness and syncope at rest or under stress, in rare cases, sudden cardiac death.
Diagnosis includes standard electrocardiogram (standard ECG) with long rhythm strip, long-term, exercise ECG, event recorder recording (external or implantable), echocardiography, chest X-ray, SSA mother and SS-B antibody testing Children with a congenital AV block, Borrelia serology and thyroid hormone status.
