Summary

This study looked at 140 adults who came to the emergency room with a fast heart rhythm called AVNRT. After a simple breathing and pushing technique (Valsalva maneuver) didn't work, patients received either adenosine or diltiazem through an IV. The goal was to see which drug more effectively and safely restored a normal heart rhythm.
