Sleep apnea increases the risk of arrhythmias

The risk of ventricular arrhythmias increased in people with even mild sleep apnoea. This is the conclusion of the Norwegian cardiologists, evaluating the relationship of sleep apnoea and ventricular arrhythmias.

The findings obtained in the study are based on the observation of 486 patients, whose average age was 49 years and 55 percent of them were men. In 271 patients were identified sleep apnea, other patients were the comparison group. As a result of observations in the group with a diagnosis of sleep apnea was identified 12.2% of patients with ventricular arrhythmias compared with 4.7 percent in the comparison group. These changes were accompanied by hypoxia - lack of oxygen in the blood, which was determined by saturation of blood and was in a group with nocturnal apnea 82 percent at normal rate - not less than 94 percent.

In conclusion, the researchers noted that the risk of ventricular fibrillation increases at night apnea with age, complexes arrhythmia become wider.
