Abstrakt

Atrioventricular nodal re-entrant tachycardia (AVNRT) is the most common supraventricular tachycardia (SVT) detected during pregnancy and labour. Non pharmacological treatment including vagal manoeuvres such as Valsalva manoeuvre, carotid massage and facial ice immersion are well tolerated and aid in diagnosis. Adenosine and beta-blocking agents are the first line drugs of choice to terminate an episode of SVT. The treatment requires interdisciplinary cooperation. Ideally, management of supraventricular arrhythmias should start before conception, for example by radiofrequency ablation. A small dose of beta-blocking agents can be used during pregnancy.
