Abstract:
:The magnitude and biological relevance in vivo of the beta-blocking properties, observed in vitro, of propafenone remains controversial. We studied the effects of propafenone on the heart rate response to graded stimulation of the right stellate ganglion in 13 anaesthetized, vagotomized cats. The decentralized ganglion was stimulated (3 ms, 10 to 15 V) for periods of 45 s at frequencies from 1 to 14 Hz. The effects of sympathetic stimulation on heart rate were evaluated by the relationship between stimulation frequency and changes in heart rate from control. The relationship was significantly displaced downward and to the right by propafenone (4 mg.kg-1, n = 7), indicating a blunted response to sympathetic stimulation. This effect was lost at the highest frequencies. The frequency range at which propafenone was effective is the same as that elicited in cardiac sympathetic nerves by acute myocardial ischaemia. With propranolol (0.5 mg.kg-1 n = 4), the effects on the heart rate response were similar but of greater magnitude. Another sodium channel blocker (flecainide, 4 mg.kg-1 n = 2) was administered, and no changes were observed in the heart rate response. Thus, propafenone has significant beta-blocking effects, which would be of clinical relevance during the reflex sympathetic activation consequent to myocardial ischaemia.
