Compared with those without sleep-disordered breathing and adjusting for age, sex, body mass index, and prevalent coronary heart disease, individuals with sleep-disordered breathing had four times the odds of atrial fibrillation (odds ratio [or], 4. 02; 95% confidence interval [ci], 1. 03–15. 74), three times the odds of nonsustained ventricular tachycardia (or, 3. buy viagra without prescription 40; 95% ci, 1. order viagra 03–11. 20), and almost twice the odds.
