Background: Tachyarrhythmia (TA) and bradyarrhythmia (BA) are cardiac rhythm disorders that result in the decline of quality of life. While patients with periodontitis are at a high risk of cardiovascular disease (CVD), little causal information between TA and BA has been provided to date. To assess the relationship, periodontal bacterial infection in patients with TA or BA was evaluated. Methods: The subjects were patients with TA (n = 98) or BA (n = 40) who attended Tokyo Medical and Dental University hospital. Periodontal and blood examinations were performed. Periodontopathic bacterial existence in saliva was evaluated. Results: We found that specific periodontopathic bacteria, Porphyromonas gingivalis and Prevotella intermedia, were highly detected in saliva from TA patients compared to BA subjects. The rates of hypertension and dyslipidemia were comparable between the two groups. Conclusion: Specific periodontal bacterial infection might affect TA progression.
