  • Patients may experience light-headedness, fainting, shortness of breath, heart palpitations, or chest pain.[cdc.gov]

  • atrioventricular block, 28 percent had some form of second- or first-degree atrioventricular block, and 23 percent had no conduction abnormalities. 18 Other less common manifestations include myopericarditis, bundle branch block, and heart failure. 17[aafp.org]
First-Degree Atrioventricular Block
  • He was admitted and over the course of the next few days, his rhythm regressed to Mobitz type I first-degree atrioventricular block and then to normal sinus rhythm.[ncbi.nlm.nih.gov]
  • Laboratory findings showed elevated erythrocyte sedimentation rate and C-reactive protein, bilateral temporal artery biopsy results were negative and first degree atrioventricular block was seen on electrocardiogram.[pagepress.org]
  • However, they reported that 98% of adults who develop Lyme carditis will develop first degree atrioventricular block, and 58% of those patients are likely to develop complete heart block.[healio.com]
  • atrioventricular block and PR interval greater than 30 milliseconds, as well as for patients with second- or third-degree atrioventricular block Patients with an isolated facial nerve palsy (i.e., normal cerebrospinal fluid examination) can be treated[aafp.org]
Ventricular Hypertrophy
  • Although an echocardiogram was not performed, there was autopsy evidence of left ventricular hypertrophy and focal calcification at the base of his aortic valve.[rwjms1.umdnj.edu]
Cannon A-Waves
  • No pertinent physical findings were noted except for jugular cannon A waves. His blood pressure was 100/60 mmHg with a heart rate of 50 bpm. His electrocardiogram showed a sinus rhythm with third-degree heart block and junctional escape rhythm.[innovationsincrm.com]


  • In most cases the conduction disturbances are reversed by treatment with antibiotics.[ncbi.nlm.nih.gov]
  • The progression of Lyme disease can be prevented with proper diagnosis and initial treatment.[pharmacytimes.com]
  • Among these patients, earlier ceftriaxone treatment may have been associated with complete recovery or improved LVEF, but the role of steroids remains unclear. 4 This patient's clinical course and treatment brought to question what caused her disease;[ahajournals.org]


  • This case highlights the importance of timely diagnosis and appropriate management to achieve a favorable prognosis.[ncbi.nlm.nih.gov]
  • The overall prognosis of Lyme carditis seems to be good, although delayed recovery has been described and possible late manifestations have been suggested.[rug.nl]
