AV blocks in Lyme carditis

Q: 34 years old female, diagnosed with Lyme's disease 2 weeks ago, is now in the local rural ED of Wisconsin with a syncopal episode. EKG showed a third-degree AV block. ED physician inserted a temporary pacemaker and transferred patient to the tertiary care center. Cardiology is consulted in CCU. Cardiology service should strongly consider the insertion of a permanent pacemaker?

A) True
B) False



Answer: B

Atrioventricular (AV) block due to Lyme disease is typically short-lived and does not require a permanent pacemaker. In most cases, antimicrobial therapy is sufficient in Lyme carditis, but patients who develop syncope, dyspnea, or chest pain or have second- or third-degree atrioventricular block, or a marked prolonged PR interval, or any arrhythmias may require a temporary pacemaker. The choice of antibiotics includes doxycycline, amoxicillin, or cefuroxime.
