The aim of the study was to evaluate the efficacy and safety of administered intravenously niferidil in doses 10, 20 and 30 mkg per kg in patients with persistent atrial fibrillation (AF) and flutter (AFL) for pharmacological cardioversion. The study

L-type Ca(2+) current (I(Ca,L)) has been shown to play a crucial role in initiation of early after depolarization (EAD) in cardiomyocytes. To study the possible role of EAD in spontaneous initiation of atrial fibrillation (AF), we tested the effects

To study the possible role of intracellular Ca2+ overload in initiation of cholinergic-dependent atrial fibrillation (AF), we tested the effects of ryanodine in canine models of AF. In anesthetized open-chest dogs (n=10) AF was induced by two methods

A perfusion with normal Tirode solution containing isoproterenol, acetylcholine and their combination into the sinus node artery of the anesthetized open-chest dogs was used to induce atrial fibrillation. The perfusion of isoproterenol, alone, was un

Systemic infusion of ryanodine did not prevent induction of atrial fibrillation (AF) during acetylcholine (Ach) perfusion in frogs. The AF, however, appeared later as of the dogs/Ach perfusion start and lasted for a shorter time as compared with the

Epicardial atrial mapping in open-chest dogs during different cholinergic influences has shown that, in acetylcholine administration and vagal stimulation, spatial distribution of atrial premature depolarisation (APDs) seems to be similar to prevalen

Patterns of atrial activation of ectopic pulse source during vagal stimulation were studied on atrial epicardial surface and atrial septum in mongrel dogs. Epicardial activation maps were drafted. The findings show that, irrespective of preferred dir

Epicardial mapping (254 unipolar electrodes) of the dog heart both atria was performed to determine spatial distribution of arrhythmic events. The mapping showed that the first atrial premature depolarisation (APD) emerged from ectopic foci, it showe

The voltage clamp experiments were carried out on single internally perfused rat myocardial cells. The effect of ethmozine (8 x 10(-5) g/ml) and lidocain (8 x 10(-6) g/ml) on the fast maximum inward sodium current (INa) was studied. The drugs were te

The emergence of ventricular tachycardia (VT), its temporal progress and response to high-frequency stimulation were studied in 10 dogs subjected to two-step occlusion of the left descending coronary artery (LDA). Within two hours after the LDA ligat
