WebFeb 5, 2024 · Atrioventricular nodal reentrant tachycardia (AVNRT) is a type of paroxysmal supraventricular tachycardia that results due to the presence of a reentry circuit within or adjacent to the AV node. The diagnosis of AVNRT requires visualization on an electrocardiogram (ECG). WebA total of 94.7% of AVNRT and 87% of AVRT could be diagnosed correctly considering both clinical and ECG criteria. Conclusion: Pounding sensation in the neck and presyncope along with ECG features like identifiable P wave after QRS complex, pseudo r′/s waves and limb lead ST-T changes very accurately differentiate AVNRT and AVRT. child with chest infection
