Differential effect of adenosine on anterograde and retrograde fast pathway conduction in patients with atrioventricular nodal reentrant tachycardia.

abstract：BACKGROUND:Frequent premature ventricular complexes (PVCs) can cause a decline in left ventricular ejection fraction (LVEF). We investigated whether the site of origin and other PVC characteristics are associated with LVEF. METHODS:We retrospectively studied 70 consecutive patients (mean age 42 ± 17 years, 40 [57%] fe...
