Key result
Selective radiofrequency ablation of the slow pathway successfully restored atrioventricular synchrony and eliminated symptomatic arrhythmia in a patient with sinus tachycardia.
Why the study?
Does selective radiofrequency ablation of the slow pathway eliminate symptomatic arrhythmia in a patient with sinus tachycardia and perpetuating slow pathway conduction?

Does selective radiofrequency ablation of the slow pathway eliminate symptomatic arrhythmia in a patient with sinus tachycardia and perpetuating slow pathway conduction?
Selective radiofrequency ablation of the slow pathway can successfully treat symptomatic sinus tachycardia with perpetuating slow pathway conduction by restoring AV synchrony.
May support slow pathway ablation in refractory sinus tachycardia; leaves open need for prospective trials.
We report a case of sinus tachycardia with perpetuating slow pathway (SP) conduction in a 42-year-old woman who developed severe symptoms as a result of atrioventricular (AV) desynchronization. The restoration of an AV synchrony, achieved with selective radiofrequency ablation of the SP, eliminated the symptomatic arrhythmia and may represent a reasonable therapeutic option despite the fact that the patient has no AV-node reentrant tachycardia. This case demonstrates the importance of AV timing.

Huang et al. (2010) conducted a case report in Symptomatic sinus tachycardia with perpetuating slow pathway conduction (n=1). Selective radiofrequency ablation of the slow pathway was evaluated on Elimination of symptomatic arrhythmia and restoration of atrioventricular synchrony. Selective radiofrequency ablation of the slow pathway successfully restored atrioventricular synchrony and eliminated symptomatic arrhythmia in a patient with sinus tachycardia.
