“…Changes in the autonomic tone have been described after fast- and slow-pathway ablation for AV node tachycardia [8–10, 16]. In contrast to previous studies, which have shown changes immediately or the next day after RFA [14, 16, 19, 21], we found the changes in autonomic tone of the heart during the late follow-up period.…”

“…In contrast to previous studies, which have shown changes immediately or the next day after RFA [14, 16, 19, 21], we found the changes in autonomic tone of the heart during the late follow-up period. Only two other studies have demonstrated changes in autonomic tone during a 6-month to 1-year follow-up period after accessory pathways and AV node slow-pathway RFA [8, 10]. …”

“…Alterations of heart rate (HR) and the presence of persistent, innapropriate sinus tachycardia, particularly after atrioventricular (AV) node slow-pathway ablation, have been reported for a variable percentage of patients [8–10]. It is suggested that disturbances of autonomic tone may be a contributing factor [9].…”

This study was designed to assess the changes in the conductive system, autonomic dysfunction, and global and regional function of the atria and ventricles in children late after slow-pathway radiofrequency ablation (RFA). The study enrolled 22 children, who has successfully undergone RFA 2 to 5 years previously (RFA group) and 20 healthy children (control group). Electrophysiologic study was performed for the RFA group. Holter monitoring and echocardiography were performed for all the children. At a late follow-up assessment, the RFA children were free of paroxysms, whereas 8 of the 22 children (36%) reported transient palpitations. Both mean and maximal heart rates (HR) were significantly increased, whereas indices of HR variability (% of succesive normal sinus RR intervals exceeding 50 ms [pNN50], root mean square of the succesive normal sinus RR interval difference [rMSSD], high-frequency component [HFC]) were significantly decreased in the RFA group compared with preablation and control data. Left atrial (LA) and right atrial (RA) volumes were significantly higher, and atria deformation indices were significantly lower in the RFA group. Correlations were found between the mean HR and the volumes of LA (r = 0.477; p < 0.001) and RA (r = 0.512; p < 0.001). A negative correlation between the maximal LA volume and the longitudinal strain rate (SR) during relaxation (r = –0.476; p = 0.03) and a positive correlation between the minimal LA volume and both longitudinal SR (r = 0.361; p = 0.03) and strain (ε) (r = 0.375; p = 0.024) during contraction were shown. These data suggest a possible link between atrial dysfunction and the hyperadrenergic state after RFA.

“…Most frequently IST develops after ablation of fast or slow pathway of atrioventricular (AV) node in patients with AV nodal reentrant tachycardia (AVNRT) or parahisian accessory pathways . So far, the mechanism of postablation IST is not well understood . Sinus tachycardia following catheter ablation is relatively common, with an incidence above 10%, but it is generally short‐lasting and usually does not require any treatment .…”

Sinus tachycardia is commonly encountered in clinical practice and when persistent, can result in significant symptoms and impaired quality of life, warranting further evaluation. On the other hand, a growing body of epidemiological and clinical evidence has shown that high resting heart rate (HR) within the accepted normal range is independently associated with increased risk of all-cause and cardiovascular mortality. However, higher HR as a risk factor for adverse cardiovascular outcomes is frequently underappreciated. In this review, we focus on two challenging problems that span the spectrum of abnormally fast sinus HR. The first section reviews inappropriate sinus tachycardia, a complex disorder characterized by rapid sinus HR without a clear underlying cause, with particular emphasis on current management options. The latter section discusses the prognostic significance of elevated resting HR and reviews clinical evidence aimed at modifying this simple, yet highly important risk factor.
