Is cardiac involvement found also in European erythema migrans borreliosis?
During an infection with Borrelia burgdorferi two men (aged 59 and 61 years, respectively) developed long-lasting cardiac arrhythmias which proved difficult to treat (tachycardias; in one patient due to atrial fibrillation, and also nodal arrhythmias). The cardiac signs completely regressed after specific antibiotic treatment, supporting the view that the cardiac involvement was due to borrelia infection, as is known to have occurred with Lyme disease reported from the USA.
