Calcium Channel Blocker or Adenosine for SVT

I had  a patient with perisstent Supraventricular tachycardia (SVT). My approach usually starts with REVERT, and if unsuccessful will continue with Adenosine. Adensoine with its rapid onset, and short half-life regardless of teribble expeince for patient is a great medication, but in this particular patient in 2 occasions was converting SVT to Sinus rhythm and after 30 minutes , patient return to SVT. Diltiazem was my next choice that converted patient to sinus rhythm without any bad experince for patient.
