According to clinical guidelines a symptomatic atrioventricular block (AV block) is treated with a pacemaker. For young individuals such a therapy can be difficult due to possible long term complications such as infections, lead disruptions and pacemaker induced cardiomyopathy. We describe a twenty year old man with recurrent syncopes due to intermittent parasympathetic caused AV block of grade 2. The patient underwent cardioneuroablation where parasympathetic ganglia in the right atrium were ablated. After the procedure the PR interval normalized. This procedure has never been performed in Iceland before and there is a limited amount of case reports in the literature.
