Characteristics of Right-Sided Accessory Pathways Associated With Right Cardiac Veins
Authors' conclusion
The RCV-AP is a rare form of right-sided APs characterized by atrial insertions distant from the annulus. ECG-speculated ventricular insertion sites conformed to the location of identified RCVs.
Study context
