Multicenter Study
Atypical Fast-Slow Atrioventricular Nodal Reentrant Tachycardia Incorporating a "Superior" Slow Pathway: A Distinct Supraventricular Tachyarrhythmia.
The existence of an atypical fast-slow (F/S) atrioventricular nodal reentrant tachycardia (AVNRT) including a superior (sup) pathway with slow conductive properties and an atrial exit near the His bundle has not been confirmed. ⋯ sup-F/S-AVNRT is a distinct supraventricular tachycardia, incorporating an SP located above the Koch triangle as the retrograde limb, that can be eliminated by radiofrequency ablation.

Randomized Controlled Trial Multicenter Study
Effects of Ranolazine on Angina and Quality of Life After Percutaneous Coronary Intervention With Incomplete Revascularization: Results From the Ranolazine for Incomplete Vessel Revascularization (RIVER-PCI) Trial.
Angina often persists or returns in populations following percutaneous coronary intervention (PCI). We hypothesized that ranolazine would be effective in reducing angina and improving quality of life (QOL) in incomplete revascularization (ICR) post-PCI patients. ⋯ URL: http://www.clinicaltrials.gov.
