Pregnancy in a Patient With Sick Sinus Syndrome and a Permanent Pacemaker

Sick sinus syndrome (SSS) is a disorder of the sinoatrial node characterised by impaired pacemaker function and abnormal impulse transmission, resulting in arrhythmias. Definitive treatment involves replacing the defective pacemaker with a synthetic one. With well-functioning pacemaker support, patients with SSS can achieve successful pregnancy outcomes. Here, we are reporting a case of a 29-year-old woman in her first pregnancy, who was diagnosed with SSS. Three years back, she was evaluated for this condition in view of her history of recurrent blackouts. She underwent permanent pacemaker implantation, which significantly improved her symptoms, and she was maintained on bisoprolol. Her pregnancy was managed jointly with the cardiology team, and her pacemaker function was closely monitored. Fetal growth was monitored using serial scans and was within normal limits. She went into spontaneous labor at 39 weeks of gestation, received epidural analgesia for pain relief, and had a successful vaginal delivery without any complications.
