| Summary: | Aim. To study the parameters of left atrium (LA) deformation for evaluation of left atrium deformation in diastolic dysfunction of the left ventricular (LV) and at least one known episode of paroxysmal AF or persisting AF with normal volumes of atriums.Material and methods. The controlled study is performed in 45 patients with diastolic dysfunction of the LV and at least one known episode of paroxysmal (PXAF) of persisting (PSAF) atrial fibrillation with normal chambers volumes, by studying of EchoCG parameters of maximum deformation and other parameters of the LA for definition of atrial functioning in the conditions of LV dysfunction.Results. By the data obtained in the study, in sinus rhythm patients and episodes of PXAF and PSAF, volumes of the LA and parameters of maximum deformity do differ from those in healthy individuals. Within these conditions LA works with more overload. Patients with PXAF and PSAF have, by 96 h EXG monitoring, more supraventricular extrasystoles.Conclusion. In AF patients the parameters of LA differ among the groups of patients with PSAF and PXAF and are more benign in PXAF. |
