Antiarrhythmic effects of coronary vasodilators on canine ventricular arrhythmia models.
Antiarrhythmic effects of intravenous coronary vasodilators (verapamil, diltiazem, bepridil, trimetazidine and nicorandil) were evaluated using two canine ventricular arrhythmia models (halothane-adrenaline arrhythmia and digitalis arrhythmia), and the minimum effective plasma concentrations of the drugs were determined for each arrhythmia model. Verapamil (0.1 mg/kg), diltiazem (0.1 mg/kg), be...

Background and Purpose: Digitalis species and their cardiac glycosides are used in congestive heart failure (ÇHF) disease. Digitalis nervosa are grown only in the North regions of Ïran. Çardiac glycosides of other species are identified by HPLÇ procedure. Ïn this research, cardiac glycosides of Digitalis nervosa were identified. Materials and Methods: Ïn this research, methanol as solvent ...
متن کاملAntiarrhythmic Effect of the Ethanol Extract of Pomegranate Mesocarp on Isolated Heart Following Ischemia and Reperfusion
Aims: Ischemic heart disease is the most prevalent cause of mortality in current populations. In recent years, many researchers have focused on plants to discover new natural therapeutic agents. The aim of this study was to evaluate the antiarrhythmic effect of the ethanolic extract of pomegranate mesocarp on rat isolated heart following myocardial ischemia and reperfusion. Materials & Methods...
متن کاملInteraction of epinephrine and ouabain on automaticity of canine Purkinje fibers.
The interaction of ouabain and epinephrine on diastolic depolarization of canine Purkinje fibers was studied using conventional microelectrode techniques. When the Purkinje fibers were treated with ouabain alone, they developed slow diastolic depolariza-tion accompanied by a proportionate decrease in the maximum diastolic potential. When these digitalized Purkinje fibers were further treated wi...
متن کاملComparison of the Action of Ouabain on the Heart in Hypothyroid , Euthyroid and Hyperthyroid Dogs
• Although, it is assumed that digitalis glycosides are relatively ineffective in heart failure and atrial fibrillation associated with disorders of thyroid gland function," there is little experimental work to support this belief. Frye and Braunwald observed that administration of triiodothyronine to euthyroid and hypothyroid patients with chronic atrial fibrillation increased the dose of card...
