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.
