## TL;DR

This case report discusses an elderly patient with sick sinus syndrome who had a rare combination of tachycardia and bradycardia, successfully treated with ablation.

## Contribution

The novelty lies in presenting a rare case of orthodromic tachycardia associated with sick sinus syndrome successfully treated with ablation.

## Key findings

- A case of tachycardia-bradycardia syndrome with syncope was successfully treated with ablation of an accessory pathway.
- Post-ablation, the patient did not experience syncope recurrence.
- Orthodromic tachycardia combined with significant pauses is a rare presentation of sick sinus syndrome.

## Abstract

El síndrome taquicardia-bradicardia es la forma de presentación más frecuente del síndrome del nodo sinusal enfermo, y comúnmente se caracteriza por episodios de fibrilación auricular paroxística seguidos de pausas significativas, sobre todo en pacientes adultos mayores; otras taquiarritmias frecuentemente asociadas son la taquicardia auricular y el flutter auricular. La asociación entre una taquicardia ortodrómica y pausas significativas en estos pacientes es una presentación poco habitual. Presentamos el caso de un adulto mayor con síndrome taquicardia-bradicardia asociado a síncope, que presentaba episodios de taquicardia incesante por vía accesoria oculta y que luego de la ablación exitosa de la misma, no volvió a presentar síncope.
