Table 5. Predictors of heart conduction disturbances based on simple regression analysis.

Parameter	OR (95% CI)	P-level
BMI	1.10 (1.03–1.17)	Р = 0.008
LVH presence	3.67 (0.82–16.48)	Р = 0.09
Beta-blockers	0.33 (0.09–1.22)	Р = 0.10
AHI	1.02 (1.01–1.04)	Р = 0.006
Maximal duration of sleep apneas	1.03 (1.01–1.04)	Р = 0.001
Mean nocturnal oxygen saturation	0.93 (0.86–1.01)	Р = 0.099
Minimal nocturnal oxygen saturation	0.95 (0.91–0.99)	Р = 0.019
