Selective slow pathway ablation does not alter enhancement of vagal tone on sinus and atrioventricular nodal function

Abstract

We studied the effects of edrophonium on sinus cycle length, atrioventricular (AV) nodal fast pathway refractoriness, and AV nodal Wenckebach cycle length in 21 patients with AV nodal reentrant tachycardia (AVNRT) who received edrophonium, and 8 patients who received phenylephrine before and after selective slow pathway ablation. Changes in sinus cycle length, fast pathway conduction, and refractoriness were not altered by radiofrequency ablation of the slow pathway, suggesting that parasympathetic denervation does not occur after slow pathway ablation of AVNRT.

Cardiovascular Diseases: Risk Factors

Cardiovascular disease is a significant health concern. Risk factors include hypertension, obesity, dyslipidemia and smoking. Women who are postmenopausal are at an increased risk of heart disease. Here is the latest research for risk factors of cardiovascular disease.
