[Atrial Flutter: up-to-date Problem Evaluation with Clinical Positions].

The review provides current ideas about the etiology and prevalence of atrial flutter (AF), mechanism and substrate of arrhythmogenesis, and principles of clinical and electrophysiological classification of this arrhythmia. Methods for conservative and surgical treatments of AF, including their comparative aspect, are described in detail. The review presented recent data on efficacy and potential risks of different approaches to reversing the arrhythmia.

[Arterial hypertension as a risk factor of intra-atrial thrombosis in patients with atrial fibrillation of non-valvular etiology].

Unlabelled: The article considers the influence of arterial hypertension on the frequency of intra-atrial thrombosis in patients with atrial fibrillation (AF) of non-valvular etiology.

Materials And Methods: 38 patients were examined (26 men and 12 women) aged 35 to 75 years with documented AF. Paroxysmal AF was diagnosed in 10 patients (26.

[Primary generalized amyloidosis with restrictive cardiomyopathy and severe chronic cardiac insufficiency].

The paper reports a case of restrictive cardiomyopathy due to cardiac amyloidosis. Diagnosis of this condition encounters difficulty created by the absence of pathognomonic symptoms of the disease. Major manifestations of amyloid cardiomyopathy are refractive chronic cardiac insufficiency, absence of cardiomyalgia, marked deterioration of diastolic filling of both ventricles, systemic hypotension, and disturbed heart rhythms.

[Relationship of variability of blood pressure, cardiac sinus rhythm, and structural and functional characteristics of the left ventricular myocardium in elderly and senile patients with arterial hypertension].

The variability of blood pressure (BP), autonomic cardiac sinus rhythm regulation, and myocardial structural and functional characteristics of the left ventricle (LV) was comparatively analyzed in 201 patients aged 65-88 years who had uncomplicated systolic and diastolic and isolated systolic arterial hypertension (SDAH and ISAH, respectively). There was a greater variability of systolic and diastolic BP no matter what the type of arterial hypertension (AH) was. It was ascertained that ISAH was characterized by absolute parasympaticotonia and SDAH was marked by relative sympaticotonia with the involvement of central ergotropic and humoral-and-metabolic mechanisms.
