[PREVALENCE OF ATRIAL RHYTHM DISTURBANCES IN CARDIAC PATIENTS WITH COMORBIDITIES].

Atrial arrhythmias are the most common among all cardiac arrhythmias. The prevalence of atrial arrhythmias is increasing worldwide and has an impact on health indicators such as the loss of ability to work and mortality and increases the overall cardiovascular risk and/or heart disease occurence. This study indicates a high prevalence of atrial arthythmias in patients with ischemic heart disease and requires more detailed study in order to develop methods of preventing the onset of cardiac rhythm disorders.
