Long RP tachycardia

A 50 yr old pt with LLQ pain and found to have a renal stone. 

What are the probable rhythm diagnosis?

The probable ECG interpretations are:
  • Atrial tachycardia
  • Atypical AV nodal reentry tachycardia (AVNRT) - fast-slow or fast antegrade and slow retrograde pathway.
  • Paroxysmal junctional reciprocating tachycardia - AV conduction over the AV node and the ventriculo-atrial conduction over a slowly conducting accessory pathway.
