A patient with complete heart block due to
ankylosing spondylitis
exhibited an unusually brisk increase in ventricular rate with exercise. Despite broad ventricular (QRS) complexes, His bundle electrograms demonstrated a His deflection before each QRS complex and thus established the level of atrioventricular (A-V) block to be proximal to or localized to the His bundle. A junctional pacemaker accounted for the brisk response to exercise, atropine, or isoproteronol.
Left bundle branch block
pattern and prolongation of infranodal conduction time (H-Q) suggested additional disease involving the His bundle and/or right fascicle. Wide-spread disease affecting A-V nodal and infranodal conduction was compatible with pathologic changes seen in this disease. Because the pacemaker was able to respond to stress promptly and with appropriate increase in heart rate, the patient appeared not to warrant pacemaker implantation in his present state.

Reiter's syndrome was found in three men who presented with cardiac conduction disturbances. In two patients, Reiter's syndrome had been present for more than 30 years and had been previously unrecognized. These patients included a 67 year old man with complete heart block of 13 years' duration, and his son, who had
left bundle branch block
and chronic generalized cardiomyopathy. A chart review of 19 other patients with Reiter's syndrome who were seen at this institution disclosed five patients with conduction abnormalities. Transient first-degree heart block was the most common disturbance detected and was usually associated with active Reiter's syndrome. Some conduction abnormalities appeared after a long latent period at a time when other manifestations of Reiter's syndrome were inactive. An association with this disorder was therefore not obvious. In all five patients with Reiter's syndrome and conduction disturbances, testing for B27 antigen gave positive results. Both clinical and histopathologic changes in the heart in Reiter's syndrome are analogous to those in
ankylosing spondylitis
, also associated with B27 antigen. We suggest that the heart, like the joints and iris, may be a target organ for B27-associated disease by a mechanism that remains to be defined.

Ankylosing spondylitis often involves a heart, such as aortic or mitral regurgitation, conduction disorder, or cardiomyopathy. We present a 34-year-old male patient with
ankylosing spondylitis
who has severe aortic regurgitation, mild mitral stenosis, and a conduction disturbance of the
left bundle branch block
, identified using multimodal images.
