[New data on etiology of heart conduction disturbances].

Aim: To make a clinicogenealogical analysis of different types of heart conduction disturbances in families of Krasnoyarsk city.

Materials And Methods: 104 probands with ECG-verified idiopathic forms of atrioventricular and intraventricular blocks of different severity and 331 their close relatives (kinship degree I and II) were examined using standard clinical investigations, ECG, echocardioscopy, electrophysical investigations in some cases and coronarography.

Results: All the observed 104 families were divided into 3 groups according to the type of heart conduction in proband.

[Combined use of left atrial transesophageal pacing and cordarone in atrial flutter].

Aim: To investigate the effectiveness of superfrequent transesophageal left atrial stimulation (TLAS) and its combination with cordarone in management of atrial flutter (AF).
