Lyme carditis is typically associated with AV nodal conduction abnormalities. We describe the case of a 66 year old female patient, who experienced a series of syncopal attacks after several tick bites two weeks earlier. ⋯ Pacemaker implantation was not necessary. We therefore have to assume that in this patient Lyme carditis was the cause of symptomatic sinus node dysfunction.

Patients with obstructive sleep apnea (OSA) frequently suffer from cardiovascular diseases. Mechanisms like intrathoracic pressure variations, changes in blood gases (hypoxia), arousals and neurohumeral adaptation mechanisms, combined with breathing disorders are causing these cardiovascular sequelae. ⋯ A systematic anamnesis with questions to daytime conditions (hypersomnia, decrease of performance), snoring and apneas while sleeping is easy to ascertain, and will lead to the correct diagnosis in more than 90% of cases. The extent and need for therapy should be assessed by three criteria: 1) daytime symptoms, 2) the extent of breathing disorder and 3) cardiovascular comorbidity.
