Abstract
This case report discusses the diagnosis and management of a 25-year-old pregnant patient presenting with persistent tachycardia. The patient, with a past medical history of thyroiditis, polycystic ovarian syndrome, and obesity, was admitted due to palpitations and was diagnosed with atrial tachycardia. Despite medical management with metoprolol, adenosine, digoxin, and flecainide, the tachycardia persisted, necessitating discussion about cardiac ablation. The report emphasizes that atrial tachycardia poses a significant clinical challenge when refractory to medical therapy. It also highlights the condition's association with tachycardia-induced cardiomyopathy and the role of catheter ablation in its management. This case underscores the need for a high index of suspicion for atrial tachycardia in pregnant patients presenting with persistent tachycardia and the importance of appropriate referral for invasive management when medical therapy fails. The case also highlights that atrial tachycardia in pregnancy can be safely managed with ablation.
