Article Synopsis
- A study was conducted to assess how atrial and ventricular pacing affects left atrial (LA) function after dual-chamber pacemaker implantation in 121 subjects with sinus node disease or atrioventricular block.
- Participants were grouped based on their pacing settings, with variations in atrial and ventricular pacing loads analyzed during follow-up visits at one and three months.
- Findings showed that high atrial pacing significantly decreased LA function, particularly affecting reservoir and contractile strains, whereas re-establishing atrioventricular synchrony in other groups maintained LA function levels.
Long QT syndrome (LQTS) is majorly an autosomal dominantly inherited electrical dysfunction, but there are exceptions (Jervell and Lange-Nielsen syndrome is inherited in an autosomal recessive pattern). This disorder prolongs ventricular repolarization and increases the risk of ventricular arrhythmias, syncope, and even sudden cardiac death. The risk of fatal events is reduced during pregnancy, but dramatically increases during the 9 months after delivery, especially in patients with LQT2.

We aimed to assess the impact of atrial pacing burden on LA volumetric and functional parameters after implantation of a dual-chamber pacemaker. : The prospective study included 121 subjects with sinus node disease (SND) or atrioventricular block (AVB) that received a dual-chamber pacemaker.
