Syncope due to complete atrioventricular block and treatment with a transient pacemaker in acute rheumatic fever

Various rhythm and connection disorders can be seen in the acute phase of acute rheumatic fever. First degree atrioventricular block, one of the minor signs of acute rheumatic fever, is the most common connection disturbance in this disease. Complete atrioventricular block, which seriously affects the conduction pathways, is rare in the literature. A 15-year-old boy was admitted because of syncope caused by complete atrioventricular block and a temporary pacemaker was employed because of symptomatic complete atrioventricular block. The transient pacemaker treatment was terminated due to recovery of complete atrioventricular block on the third day of antiinflammatory treatment. Acute rheumatic fever should be kept in mind as a possible cause of acquired complete atrioventricular block. Connection disturbances in acute rheumatic fever improve with antiinflammatory treatment. Transient pacemaker treatment is indicated for patients with symptomatic transient complete atrioventricular block.
