[Electrophysiological effects of intravenous propafenone for treating atrial-ventricular nodal dual pathways reentrant tachycardia].
The acute electrophysiological effects of intravenous propafenone were studied through programmed electrical stimulation in 9 patients with atrio-ventricular nodal dual pathways reentrant tachycardia (AVNDP-RT). The results showed that propafenone prolonged significantly the effective refractory period of atrial ventricular nodal fast pathway (AVN-FP) in retrograde conduction and might further terminate the paroxysmal supraventricular tachycardia (PSVT). It is an effective drug for treating AVNDP-RT. Neither blood pressure dropping nor other side effects were observed.
