Heart Rate Variability in Awake Immobilized and Disadapted Rats under the Influence of Enalapril and Verapamil
Enalapril in immobilized rats led to the increase in a sympathetic activity whereas on the background of verapamil the increase in a parasympathetic activity were found. Experimental chronic heart failure (CHF) induced by oleothorax in rats is accompanied by activation of the vagal tone. Enalapril in rats with CHF was more effective than verapamil for heart rate variability normalization.
